Safe Servicing Practices

SAFE SERVICING PRACTICES - ALL APPLIANCES

To avoid personal injury and/or property damage, it is important that

Safe Servicing

Practices be observed. The following are some limited examples of safe practices:

1.

DO NOT attempt a product repair if you have any doubts as to your ability to complete it in a safe and satisfactory manner.

2. Before servicing or moving an appliance:

• Remove the power cord from the electrical outlet, trip the circuit breaker to the

OFF position, or remove the fuse.

• Turn off the gas supply.

• Turn off the water supply.

3. Never interfere with the proper operation of any safety device.

4.

USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE.

SUBSTITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETY

STANDARDS SET FOR HOME APPLIANCES.

5.

GROUNDING: The standard color coding for safety ground wires is GREEN, or

GREEN with YELLOW STRIPES. Ground leads are not to be used as current carrying conductors. It is EXTREMELY important that the service technician reestablish all safety grounds prior to completion of service. Failure to do so will create a hazard.

6. Prior to returning the product to service, ensure that:

• All electrical connections are correct and secure

• All electrical leads are properly dressed and secured away from sharp edges, high-temperature components, and moving parts

• All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal parts and panels

• All safety grounds (both internal and external) are correctly and securely connected

• All panels are properly and securely reassembled

ATTENTION!!!

This service manual is intended for use by persons having electrical and mechnical training and a level of knowledge of these subjects generally considered acceptable in the appliance repair trade.

Important safety instructions

WARNING

Please read all safety instructions before using your new refrigerator.

General Safety

• Do not store or use gasoline, or other flammable liquids, near this or any other appliance. Read product labels for warnings regarding flammability and other hazards.

• Do not operate the refrigerator in the presence of explosive fumes.

• Avoid contact with any moving parts of the automatic ice maker.

• Remove all staples from the carton to avoid cut injuries. Staples can also damage finishes if they come in contact with other appliances or furniture.

Child Safety

Packing Materials:

• Packing cartons covered with rugs, bedspreads, plastic sheets or stretch wrap may become airtight chambers and can quickly cause suffocation.

• Destroy or recycle the product’s carton, plastic bags, and any other exterior wrapping material immediately after the refrigerator is unpacked. Children should never play with these items.

Child Entrapment And Suffocation:

• These problems are not limited to the past.

Whether junked, abandoned or temporarily stored (even for a few hours), unattended refrigerators and freezers are dangerous.

Please take the precautions listed below.

Proper Disposal Of

Refrigerators/Freezers

Before you throw away your old refrigerator/freezer:

• Remove the doors.

• Leave the shelves in place so children may not easily climb inside.

• Have refrigerant removed by a qualified service technician.

Electrical information

WARNING

You must follow these guidelines to ensure that your refrigerator’s safety mechanisms are operating correctly.

•

The refrigerator must be plugged into its own dedicated 115 Volt, 60 Hz., AC-

only electric outlet. The power cord of the appliance is equipped with a three-prong grounding plug for your protection against electrical shock hazards. It must be plugged directly into a properly grounded threeprong receptacle. The receptacle must be installed in accordance with local codes and ordinances. Consult a qualified electrician.

Do not use an extension cord or adapter plug.

• If the power cord is damaged, it should be replaced by the manufacturer, service technician or a qualified person to prevent any risk.

• Never unplug the refrigerator by pulling on the power cord. Always grip the plug firmly, and pull straight out from the receptacle to prevent damaging the power cord.

• Unplug the refrigerator before cleaning and before replacing a light bulb to avoid electrical shock.

• Performance may be affected if the voltage varies by 10% or more. Operating the refrigerator with insufficient power can damage the compressor. Such damage is not covered under your warranty.

• Do not plug the unit into an outlet controlled by a wall switch or pull cord to prevent the refrigerator from being turned off accidentally.

• Avoid connecting refrigerator to a

Ground Fault Interrupter (GFI) circuit.

IMPORTANT

To turn off power to your refrigerator, unplug the power cord from the wall outlet.


This Use & Care Guide provides general operating instructions for your model. Use the refrigerator only as instructed in this Use & Care Guide.

Before starting the refrigerator, follow these important first steps.

Location

• Choose a place that is near a grounded electrical outlet. Do Not use an extension cord or an adapter plug.

• If possible, place the refrigerator out of direct sunlight and away from the range, dishwasher or other heat sources.

• The refrigerator must be installed on a floor that is level and strong enough to support a fully loaded refrigerator.

• Consider water supply availability for models equipped with an automatic ice maker.

CAUTION

DO NOT install the refrigerator where the temperature will drop below 55°F (13°C) or rise above 110°F (43°C). The compressor will not be able to maintain proper temperatures inside the refrigerator.

DO NOT block the toe grille on the lower front of your refrigerator. Sufficient air circulation is essential for the proper operation of your refrigerator.

Door opening

NOTE

The refrigerator doors are designed to shut by themselves within a 20 degree opening.

Your refrigerator should be positioned to allow easy access to a counter when removing food. For best use of drawers and freezer baskets, the refrigerator should be in a position where both the refrigerator and freezer doors can be fully opened.

Guidelines for final positioning of your refrigerator:

• All four corners of the cabinet must rest firmly on the floor.

• The cabinet should be level at the front and rear.

• The sides should tilt ¼ inch (6 mm) from front to back (to ensure that doors close and seal properly).

• Doors should align with each other and be level.

All of these conditions can be met by raising or lowering the adjustable front rollers.

To level the cabinet using the front rollers:

1 Open both doors and remove the toe grille by gently pulling forward (see illustration).

Connecting The Water Supply

About your refrigerator’s water supply

The automatic ice & water dispenser on your refrigerator requires a permanent water supply to function correctly. During installation, you

(or a service professional) establish this water supply by connecting a copper tube from your household water system to a valve at the rear of the refrigerator.

You may have already followed the directions in the Installation Instructions to connect the water supply. This information is repeated here for future reference if you need to relocate your refrigerator.

CAUTION

To avoid property damage:

• Use copper tubing for the water supply line (plastic tubing is more likely to leak).

Manufacturer is not responsible for any damage if plastic tubing is used for supply line.

• Ensure water supply and installation comply with state and local laws and regulations.

• For proper dispenser operation, recommended water supply pressure should fall between 30 psi and 100 psi.

Excessive pressure may cause water filter to malfunction.

What you will need:

• Access to a cold water line with pressure of

30-100 psi. (System supplied with cold water only.)

• Copper tubing with ¼ inch (6.4mm) Outside

Diameter (OD). Length for this tubing is the distance from the rear of the refrigerator to your household water supply line plus seven feet (2.1 meters).

• A shut-off valve for the connection between your household water line and the refrigerator supply line.

Do not use a self-piercing shut-off valve.

• A compression nut and ferrule (sleeve) for the water supply connection at the rear of your refrigerator.

NOTE

A kit is available from your dealer that provides all materials for a water supply installation, including

25 feet of copper tubing and full instructions.

To connect the water supply to the rear of your refrigerator:

1 Ensure that the refrigerator is not plugged in.

2 Flush the supply line until water is clear by placing the end of the copper tube in a sink or bucket and opening the shut-off valve.

3 Unscrew the plastic cap from the water valve inlet at the rear of your refrigerator. Discard the cap.

4 Slide the brass compression nut, then the ferrule (sleeve) onto copper tube.

5 Push the copper tube into water valve inlet as far as it will go (¼ inch).

6 Slide the ferrule (sleeve) into valve and finger-tighten the compression nut onto valve.

Tighten another half turn with a wrench. Do not over-tighten.

7 Secure the copper tube to your refrigerator’s rear panel with a steel clamp and screw (see illustration).

8 Coil the excess copper tubing (about 2½ turns) behind your refrigerator as shown.

Arrange coiled tubing to avoid vibration or wear against other surfaces.

9 Open water supply shut-off valve and tighten any connections that leak.

glass shelves, which are designed to catch and hold accidental spills. These shelves slide out for easy access to food and faster cleaning.

Sliding shelves can be pulled forward as far as their built-in stops allow. Sliding shelves cannot be separated from their mounting brackets.

Drawers

Your refrigerator includes a variety of storage drawers. These drawers usually are located in fixed positions at the bottom of the fresh food compartment.

Crispers

Crisper drawers are designed for storing fruits, vegetables, and other fresh produce. Before storing items in a crisper:

• Wash items in clear water and remove excess water.

• Wrap any items that have strong odors or high moisture content.

NOTE

Leafy vegetables keep best when stored with the Humidity Control set on Higher Humidity, or in a drawer without a Humidity Control. This keeps incoming air to a minimum and maintains maximum moisture content.

Crisper humidity control

Crisper drawers include a sliding control for adjusting the humidity inside the crisper. This feature can extend the life of certain fresh vegetables that keep longer in high humidity.

Meat keeper

Some models are equipped with a meat keeper drawer for short-term storage of bulk meat items.

This drawer includes a sliding control for adjusting the temperature inside.

Any meat to be kept longer than two days should be frozen. If you store fruits or vegetables in this drawer, set it to a warmer temperature to prevent freezing.

Doors

Storage bins

The doors to your freezer and fresh food compartments use a system of modular storage bins. All of these bins are removable for easy cleaning. Some of them have fixed positions, while others can be adjusted to your needs.

Door bins are ideal for storing jars, bottles, cans, and large drink containers. They also enable quick selection of frequently used items.

To change the position of an adjustable door bin:

1 Before adjusting a bin, remove all food.

2 Grip the bin firmly with both hands and lift it upward.

3 Remove the bin.

4 Place the bin just above desired position.

5 Lower the bin onto supports until locked in place.

Special items rack

The innovative design of the special items rack allows you to store four bottles of wine or soft drink bottles.

16


Accessories

Tall bottle retainer

The tall bottle retainer keeps tall containers in the bin from falling forward when opening or closing the refrigerator door.

To install, snap the ends of the retainer over the edge of the retainer wall as shown in the illustration.

Can rack

The can rack allows you to efficiently and securely store up to six 12-ounce cans of beverage drink.

Extra shelf

The extra shelf attaches to the top of the ice dispenser container.

It allows storage of both round and rectangular cartons such as your favorite ice cream.

Pizza rack (some models)

This rack is attached to the freezer wall beside the ice dispenser container.

This convenient area allows for storage of pizza and other tall items placed vertically between the ice dispenser container and the freezer wall.

Can Rack

Dairy compartment

Use the dairy compartment, at the top of the fresh food compartment door, for short term storage of cheese, spreads, or butter. The dairy compartment, which includes a lift-up cover that may be locked and a dairy divider (some models), is designed to be warmer than the open storage area to accommodate these types of food.

17

Priming the water supply system

Your refrigerator’s water supply system includes several tubing lines, an advanced water filter, a distribution valve bank, and a reserve tank to ensure ample supply to the ice and water dispenser at all times. This system needs to be completely filled with water when first connected to an external supply line.

CAUTION

For proper dispenser operation, recommended water supply pressure should fall between 30 psi and 100 psi.

Excessive pressure may cause water filter to malfunction.

To prime the water supply system:

1 Begin filling the tank by pressing and holding a drinking glass against the water dispenser paddle.

2 Keep the glass in this position until water comes out of the dispenser.

It may take about 1½ minutes.

3 Continue dispensing water for about three minutes to flush the system and plumbing connections of any impurities (stopping to empty the glass as necessary).

Using the ice maker after installation

IMPORTANT

The ice maker is turned on at the factory so it can work as soon as you install your refrigerator. If you cannot connect a water supply, turn the ice maker’s On/Off switch to Off. Otherwise, the ice maker’s fill valve may be noisy when it attempts to operate without water.

Before making ice for the first time, be sure to prime the water supply system. Air in new plumbing lines can result in two or three empty ice maker cycles. Furthermore, if the system is not flushed, the first ice cubes may be discolored or have an odd flavor.

Turning the ice maker on and off

Ice production is controlled by the ice maker’s

On/

Off power switch. To gain access to the ice maker, pull the extra shelf out (some models). Press the switch to the “ O” position to turn it Off and press to the “ I” position to turn it On.

OR

OFF

ON

NOTE

The water dispenser has a built-in device that shuts off the water flow after three minutes of continuous use. To reset this shutoff device, simply release the dispenser paddle.

Ice maker operation & care

The ice maker, ice bin, and dispenser feeding mechanism are located in the top of the freezer compartment. After the refrigerator is installed properly and has cooled for several hours, the ice maker can produce ice within 24 hours. It can completely fill an ice bin in about two days.

The ice maker produces four to six pounds of ice every 24 hours depending on usage conditions. Ice is produced at a rate of eight cubes every 75 to 90 minutes.

NOTE

The ice maker also has a built-in wire signal arm, which automatically stops ice production when the ice bin is full. This signal arm should not be used to manually stop the ice maker.

18


Ice maker/dispenser tips

• Ice cubes stored too long may develop an odd flavor. Empty the ice container as explained below.

• Occasionally shake the ice container to keep ice separated.

• If your refrigerator is not connected to a water supply or the water supply is turned off, turn off the ice maker by pressing the On/Off switch.

• If you need a large quantity of ice at one time, it is best to get cubes directly from the ice container.

• The following sounds are normal when the ice maker is operating:

- Motor running

- Ice dropping into ice container

- Water valve opening or closing

- Ice loosening from tray

- Running water

• When dispensing ice, you will hear a snapping or clicking sound when the ice chute opens and closes.

• Turn off the ice maker when cleaning the freezer and during vacations.

- If you turn off the ice maker for a long period of time, you should also turn off the water supply valve.

4 Allow the ice bin to dry completely before replacing in the freezer.

5 Remove ice chips and clean the ice bin shelf and the freezer door chute.

6 Replace the ice bin. Press the ice maker’s

Off/On switch to resume ice production.

Remove and empty the ice storage bin if:

• An extended power failure (one hour or longer) causes ice cubes in the ice storage bin to melt and freeze together, jamming the dispenser mechanism.

• You do not use the ice dispenser frequently.

Ice cubes will freeze together in the bin, jamming the dispenser mechanism.

Remove the ice storage bin and shake to loosen the cubes or clean as explained above.

Never use an ice pick or similar sharp instrument to break up the ice. This could damage the ice storage bin and dispenser mechanism.

IMPORTANT

When removing or replacing the ice bin, DO NOT rotate the auger in the ice bin. If the auger is accidentally rotated, you must realign the auger by turning it in 90 degree turns until the ice bin fits into place with the drive mechanism.

If the auger

is not properly aligned when replacing the ice bin, the refrigerator will only dispense Crushed

Ice. The freezer door may also not close properly causing warm air to leak into the freezer.

CAUTION

Chemicals from a malfunctioning water softener can damage the ice maker. If the water supply to your refrigerator is softened, be sure the softener is maintained to work properly.

Cleaning the ice maker

Clean the ice maker and ice bin at regular intervals, particularly before you take a vacation or move.

To clean the ice maker:

1 Turn off ice production by pressing the ice maker’s Off/On switch.

2 Remove the ice bin by lifting up and out.

3 Empty and carefully clean the ice bin with mild detergent. Rinse with clear water. Do not use harsh or abrasive cleaners.

Locating the filters

Your refrigerator is equipped with separate water and air filtering systems. The water filter system filters all dispensed drinking water, as well as the water used to produce ice. The air filter removes odors and impurities from the refrigerator compartment.

Water filter

The water filter is located at the top right side of the fresh food compartment.

Air filter

The air filter is located at the top of the fresh food compartment next to the water filter.

Replacing the air filter

In general, you should change the air filter every six months (the filter status light on the Touch Panel prompts you to replace the filter after six months) to ensure optimal filtering of refrigerator odors. You may want to adjust this time period depending on the types and amounts of food you typically store in your refrigerator. To replace your

PureAdvantage

TM air filter:

1 Pull the air filter housing straight out.

2 Remove the old filter and discard it.

3 Unpackage the new filter and place it inside the housing.

4 Slide the housing back into position.

When the display changes from “ Replace” to

“ Good,” the status has been reset.

6 The

Filter Reset will turn itself off after a few seconds.

NOTE

The electronic touch panel, located at the freezer door, includes controls to monitor the status of your air filter. See the previous section for more information about these controls.

Replacing the water filter

In general, you should change the water filter every six months to ensure highest possible water quality.

The Filter Status light on the Touch Panel prompts you to replace the filter after a standard amount of water (400 gallons for

PureAdvantage

TM

) has flowed through the system.

If your refrigerator has not been used for a period of time (during moving for example), change the filter before reinstalling the refrigerator.

Ideas for storing foods

Fresh food storage

• Keep the fresh food compartment between 34° F and 40° F with an optimum temperature of 37° F.

• Avoid overcrowding the refrigerator shelves, which reduces air circulation and causes uneven cooling.

Fruits and vegetables

• Store fruits and vegetables in crisper drawers, where trapped moisture helps preserve food quality for longer time periods.

Meat

• Wrap raw meat and poultry securely so leakage and contamination of other foods or surfaces does not occur.

• Use the meat keeper drawer for short-term storage. Any meat to be kept longer than two days should be frozen.

Frozen food storage

• Keep the freezer compartment at 0° F or lower.

• A freezer operates most efficiently when it is at least ²⁄₃ full.

Packaging foods for freezing

• To minimize food dehydration and quality deterioration, use aluminum foil, freezer wrap, freezer bags or airtight containers.

Force as much air out of the packages as possible and seal them tightly. Trapped air can cause food to dry out, change color, and develop an off-flavor (freezer burn).

• Wrap fresh meats and poultry with suitable freezer wrap prior to freezing.

• Do not refreeze meat that has completely thawed.

Loading the freezer

• Avoid adding too much warm food to the freezer at one time. This overloads the freezer, slows the rate of freezing, and can raise the temperature of frozen foods.

• Leave a space between packages, so cold air can circulate freely, allowing food to freeze as quickly as possible.

• Avoid storing hard-to-freeze foods, such as ice cream and orange juice, on the freezer door shelves. These foods are best stored in the freezer interior where the temperature varies less.

Ideas for saving energy

Installation

• Locate the refrigerator in the coolest part of the room, out of direct sunlight, and away from heating ducts or registers. Do not place the refrigerator next to heat-producing appliances such as a range, oven, or dishwasher. If this is not possible, a section of cabinetry or an added layer of insulation between the two appliances will help the refrigerator operate more efficiently.

• Level the refrigerator so that the doors close tightly.

Food storage

• Avoid overcrowding the refrigerator or blocking cold air vents. Doing so causes the refrigerator to run longer and use more energy.

• Cover foods and wipe containers dry before placing them in the refrigerator. This cuts down on moisture build-up inside the unit.

• Organize the refrigerator to reduce door openings. Remove as many items as needed at one time and close the door as soon as possible.

22


Understanding the sounds you may hear

Your new, high-efficiency refrigerator may introduce unfamiliar sounds. These sounds normally indicate your refrigerator is operating correctly. Some surfaces on floors, walls, and kitchen cabinets may make these sounds more noticeable.

Following is a list of major components in your refrigerator and the sounds they can cause:

A Evaporator Refrigerant through the evaporator may create a boiling or gurgling sound.

B

Evaporator fan You may hear air being forced through the refrigerator by the evaporator fan.

C Defrost heater During defrost cycles, water dripping onto the defrost heater may cause a hissing or sizzling sound. After defrosting, a popping sound may occur.

D

Automatic ice maker When ice has been produced, you will hear ice cubes falling into the ice bin.

E

Electronic control & automatic defrost

control These parts can produce a snapping or clicking sound when turning the cooling system on and off.

F

Condenser fan You may hear air being forced through the condenser.

G Compressor Modern, high-efficiency compressors run much faster than in the past. The compressor may have a highpitched hum or pulsating sound.

H

Water valve Makes a buzzing sound each time it opens to fill the ice maker.

I Drain pan (not removable) You may hear water dripping into the drain pan during the defrost cycle.

J

Condenser May create minimal sounds from forced air.

K

Motorized damper May produce a light humming during operation.

L Ice dispensing paddle When dispensing ice, you will hear a snapping or clicking sound when the solenoid opens and closes the ice chute.

NOTE

Energy efficient foam in your refrigerator is not a sound insulator.

NOTE

During automatic defrost cycle, a red glow in the back wall vents of your freezer compartment is normal.


23

Protecting your investment

Keeping your refrigerator clean maintains appearance and prevents odor build-up. Wipe up any spills immediately and clean the freezer and fresh food compartments at least twice a year. When cleaning, take the following precautions:

• Never use metallic scouring pads, brushes, abrasive cleaners or strong alkaline solutions on any surface.

• Never use CHLORIDE to clean stainless steel.

• Do not wash any removable parts in a dishwasher.

• Always unplug the electrical power cord from the wall outlet before cleaning.

NOTE

If you set your temperature controls to turn off cooling, power to lights and other electrical components will continue until you unplug the power cord from the wall outlet.

• Remove adhesive labels by hand. Do not use razor blades or other sharp instruments which can scratch the appliance surface.

• Do not remove the serial plate.

CAUTION

• Pull the refrigerator straight out to move it. Shifting it from side to side may damage flooring.

Be careful not to move the refrigerator beyond the plumbing connections.

• Damp objects stick to cold metal surfaces. Do not touch refrigerated surfaces with wet or damp hands.

IMPORTANT

If you store or move your refrigerator in freezing temperatures, be sure to completely drain the water supply system. Failure to do so could result in water leaks when the refrigerator is put back into service.

Contact a service representative to perform this operation.

Refer to the guide on the next page for details on caring and cleaning specific areas of your refrigerator.

Section C - Electrical Components

Electrical Grounding

All refrigerators are equipped with a power supply cord incorporating a three-prong grounding plug and a ground wire which is attached to the refrigerator cabinet for protection against shock hazard. Each electrical component is either cabinet mounted or connected through a ground wire to the cabinet to complete the ground. Certain components, such as defrost timers, may be double insulated and do not require a ground wire.

Ensure the electrical wall receptacle is of the three prong type and is properly grounded in accordance with the National Electrical Code and/or local codes.

Compressor Electrical Components and Circuits on Models with Standard Compressor

The new series of very high efficiency compressor is equipped with all new electrical components consisting of a solid state PTC relay with a thermally operated overload protector, and a run capacitor.

Solid State Relay

The solid state relay has no moving parts. It consists of a PTC resistor mounted in a plastic case with appropriate terminals. PTC (Positive

Temperature Coefficient) simply denotes a resistor which increases in resistance as its temperature is increased. The self-heating PTC resistor used in the solid state relay has the unique characteristic of changing from low to very high resistance very abruptly, thus serving as an on-off switch. (See

Figure C1.)

The solid state relay plugs directly onto the compressor start and run terminals. Relay terminals

1, 2, and 5 are connected within the relay, as are terminals 3 and 6.

A run capacitor is connected to relay terminals 2 and

3, so it is connected in parallel with the PTC resistor.

One side of the 120 VAC power is connected to relay terminal 1. The other side of line is connected to the overload protector. (See figure C1.)

To Check/Replace Relay

1. Disconnect electrical supply to refrigerator.

2. Remove bale wire holding relay to compressor.

3. Remove relay assembly from compressor.

(See Figure C2.)

Figure C1

Figure C2

4. Use small, flat-bladed screwdriver to disconnect leads to relay assembly.

5. Use flat headed screwdriver to gently pry capacitor from relay assembly.

6. Use ohmmeter to check resistance between terminals 5 and 6. Resistance should be 3 to 12 ohms at normal room temperature. Shorted relay will read 0 ohms. Open relay will read very high or infinite resistance.

7. If ohm readings are out of range, replace relay.

8. Reverse this procedure to re-assemble.

NOTE

When replacing leads to the PTC relay, ensure locking tabs snap into terminal.

Overload Protector

The overload protector is completely thermally operated. It will open from excessive heat or current. Unlike prior overloads, the internal bimetal is not self-heating, and is not a part of the electrical circuit. The overload has a small built-in coil heater that is in series with the compressor start and run windings (See Figure

C1).


33

To Check/Replace The Overload

Protector



3. Remove relay assembly from compressor.

4. Use flat headed screwdriver to gently pry capacitor from relay assembly.

5. Use small, flat-bladed screwdriver to disconnect leads to relay assembly. (Note:

On some models you will have to remove bale wire and cover, to gain access to relay and overload protector.)

6. Use ohmmeter to check resistance between tab terminal and female pin terminal.

Overload protector should have less than 1 ohm of resistance at normal room temperature.

7. If ohm readings are out of range, install new

Starter/Overload Assembly.

NOTE

The Overload Protector is built into the

Starter Overload Assembly.

8. Reverse this procedure to re-assemble.

NOTE

When replacing leads to the PTC Relay, ensure the locking tabs snap back into the terminal.

Run Capacitor

The run capacitor has permanently attached terminals which are connected to relay terminals 2 and 3.

NOTE

Some models are not equipped with a Run capacitor.

To Check/Replace The Run Capacitor



2. Use small, flat-bladed screwdriver to disconnect leads to relay assembly.

3. Use flat-bladed screwdriver to gently pry capacitor from relay assembly.

4. Discharge capacitor by shorting across terminals with 500K (1 watt) resistor for one minute.

5. Use ohmmeter set on the

“Ohms times

1000” scale (if available), to check resistance across capacitor wire terminals.

• The needle should jump towards zero ohms and quickly move back to infinity.

• If the needle does not move, the capacitor is open.

• If the needle reads a constant value at or near zero ohms, the capacitor is shorted out.

• If the needle jumps toward zero and then moves back to constant high resistance (not infinity), the capacitor has a high resistance leak.

6. If ohm readings are out of range, replace capacitor.

7. Reverse procedures to re-assemble.

Compressor Start Circuit

When the compressor circuit is first energized, the solid state relay has low resistance (3-12 ohms), and both the run and start windings are energized to start the compressor. The run capacitor is being bypassed by the relay, and it has a minor function during compressor starting (See Figure C3).

Figure C3

34


Compressor Run Circuit

When the self-heating solid state relay has reached sufficient temperature, it will abruptly change from low resistance (3-12 ohms) to very high resistance

(10-20K ohms) and, in effect, switches off the start windings.

The relay no longer shunts the run capacitor.

The run capacitor is now in series with the start windings. The only purpose of the run capacitor is to improve compressor operating efficiency, which it does by correcting the power factor of the compressor motor (See Figure C4).

Figure C4

Compressor Operating

Characteristics

• When the compressor electrical circuit is energized, the start winding current causes the relay to heat and switch off the start winding circuit.

NOTE

The relay will switch off the start winding circuit even though the compressor has not started

(as when attempting to re-start after momentary power interruption).

• The overload protector is designed and calibrated to open the compressor electrical circuit with locked rotor run winding current on.

• With an open relay, the compressor will not start since there is little or no current to the start windings. The overload protector will open due to high locked rotor run winding current.

• With a shorted relay or capacitor, the compressor will start, and the overload protector will open.

• With an open or weak capacitor, the compressor will start and run. The compressor, however, will be operating at reduced efficiency of energy usage.

Compressor Electrical Check

If the compressor will not run, make a voltage check across the power lead terminals on the PTC

Relay. (See Figure C4.)

The voltmeter should show line voltage if the thermostat knob is in normal operating position and not in the OFF position. If this check does not show a live circuit, the control thermostat and defrost timer wiring should be checked for loose and/or broken connections.

A control thermostat check can be made by using a piece of wire as a temporary bridge across two thermostat terminals. If the compressor starts and runs with the bridge, the control thermostat is at fault and should be replaced.

If the voltage check shows power supply at the

PTC Relay terminals, use a test cord to check the compressor.

If the compressor does not start and run with the test cord, check the line voltage to see if there is more than 10% variation from the rated voltage. If voltage is correct and the compressor will not start and run, replace the compressor.

If the compressor starts and runs with the test cord, replace the PTC Relay.

The Power Input Electronic

Control (Inverter)

The solid state power input electronic control contains:

1. Low voltage power supply.

2. EMI Filter and Voltage Suppressor Circuit.

3. AC-DC Converter

4. Three-phase Inverter Bridge

5. Serial communication.

6. Microcontroller or DSP Controller Protection.

7. Voltage Sensor

115 Volts directly from the service cord. It receives a 2 to 5 volt DC signal from the main control board located under the refrigerator in the left front opening behind the bottom grill.

To Check/Replace the Inverter

1. Use your Multimeter or a good volt meter set on 300 volt AC to test the voltage going into the inverter from the product service cord. Do not disconnect the molex connector. Slide the probes from your meter along side the wires until you connect with the terminal itself. You should read 115 Volt AC + or - 10%. If less check service cord and supply voltage.

2. Set your meter to DC on a scale as close to

10 Volt as available. Do not disconnect the molex connector. Slide the probes from your meter along side the wires until you connect with the terminal itself. You should read between 2 and 5 Volt DC. If voltage is outside the 2 to 5 Volt DC range replace the main control board.

Inverter

The Inverter replaces the Solid State Relay, the

Overload Protector and the Run Capacitor. The

Inverter has 115 Volt AC current to it all the time the refrigerator is connected to line voltage. It picks up

Defrost Thermostat

The defrost thermostat is a temperature sensing device. Wired in series with the defrost timer and the evaporator defrost heater, it senses the rise in evaporator temperature during a defrost cycle and cycles the defrost heater off after all frost is melted.

It is calibrated to permit a defrost cycle only when the temperature is below a preset temperature. The contacts in the defrost thermostat are set to open at 47°F and close at 25°F.

To Test The Defrost Thermostat

1. Measure resistance across two thermostat leads at connector plug. At room temperature, resistance should be infinity.

Contacts are open.

2. Place a couple ice cubes on sides of thermostat. After a few seconds, thermostat should reset.

3. Measure resistance again. This time, reading should be 0. Contacts have closed.

4. If resistence readings is not “0”, replace defrost thermostat. Contacts are probably burnt.

To Remove The Defrost Thermostat



3. Remove ice container and rail assembly. The multiconnector at back of rail assembly must be disconnected before rail assembly will come free.

4. Loosen 2 screws holding ice maker to right side of compartment, just enough to lift ice maker free. The multiconnector must be disconnected before ice maker will come free from compartment.

5. Remove two rail assembly supports. (two screws on each one).

6. Remove four screws from evaporator cover.

7. Remove five screws on evaporator air duct cover.

8. Cut the two leads coming from thermost close to the base. You must leave enough wire coming from connector to allow for splicing tin new thermostat.

Control Removal and

Installation

CAUTION

Before servicing any part of the control system the product must be unplugged, the fuse pulled or circuit baker turned off the prevent damage to the the product the control system or personal injury to the servicer.

To service the control board you must remove the frame around the dispenser housing by pulling straight out at the top corner and working your way around the frame pulling it out of the grove in the door.

With the control removed you can remove the power supply board from the back of the control by removing the 4 screws and disconnecting the wiring harness connector for the powers board to the control.

NOTE

When handling and or replacing a control board it is important the a technician have a wrist ground strap on and connected to the cabinet or another grounding position to prevent static electricity from damaging the board.

Push the new control board down into place using caution not to damage the board on the retainer.

With the board snapped all the way down in place reinstall the control box in the top of the food compartment in reverse order from the removal instructions.

To service the power board (main power supply), open the food and freezer door. Remove the kick plate from the bottom of the cabinet. Looking through the opening at the bottom of the cabinet, on the left side you can see the plastic box containing the power board.

Then remove the screws two screws at the top of the control. Now you can lift up on the control assembly while you tip it out at the top. This will allow you to remove the control assembly from the door

With the control out you can disconnect the molex plugs form the dispenser housing to the control assembly. This will allow for complete removal of the control.

One screw in the middle of the front of the box holds the control box. Remove the screw and slide the control box forward. The back of the control box sits on a rail. Now the control box can be pulled out from the front of the refrigerator.


57

This will give you access to the wiring connectors so you can disconnect the power board and pull the control box out from the front of the refrigerator.

With the cover removed, you can reach down the right side of the damper control from the top and feel a release tab. Push out on the tab and tip the damper out from the top.

The new power board will come installed in the plastic box. This will prevent shipping damage and help with the installation.

Start the control box into the opening and reconnect the wiring using caution to make sure the wires are all the way plugged in. Now you can push the control box back in place and reinstall the screw. There is a 3 amp fuse mounted on the control board that is used to protect the board from voltage surges.

With the damper tipped out release the tab in the center of the electrical connector and unplug the wire harness from the damper.

Now the damper can be removed from the product.

To replace the damper remove the cover lifting up the light shield and removing the screw in the back section of the cover holding it to the back of the food compartment liner.

NOTE

Stepper motors require alternating polarities of

DC current to operate. This is accomplished with a circuit on the main board. Applying straight 12 V

DC to the damper motor will not make the motor run and it could damage the motor windings. Only test the damper motor through the refrigerator control system.

58


To reinstall the damper, make sure the damper door is closed all the way. Then follow the removal instructions in reverse order. Ue caution to make sure you get the wiring connector pushed all the way in. Make sure the seal on the damper connect with the liner and the cover seal so there are no air leaks when the damper door is closed.

To test, set the control system into service test mode 2 (evaporator fan motor test) and allow the fan to run on high speed. Pass a feather or small ribbon around all sides of the damper cover and look for movement indicating an air leak. If a air leak is present, you will need to remove and recheck the seals and reinstall the damper.

The food compartment temperature sensor is located next to the right hand shelf support bracket in about the middle of the back wall.

Snap the new sensor into the bracket, plug it into the connector, then push the bracket straight back into the holes in the liner.

The freezer compartment temperature sensor is located inside the housing that supports the ice bucket. The auger motor and solenoid are mounted into the back compartment of the housing.

CLIP

HOLDING

SENSOR

The cover over the temperature sensor can be removed by pulling stright out. This allow excess to the sensor snapped into the bracket on the back wall. Pull the sensor out of the bracket and unpluge it from the connector coming out of the back of the liner.

To replace the senser, remove the ice bucket, then remove the two screws at the bottom of the housing that hold the housing assembly to the the rails attached to the liner. With the screws removed lift the housing up about 1/2 inch and pull forward.

Holding the housing assembly in one hand, reach over the assembley and unplug the wiring harness from the connector coming out of the back of the liner. Turn the assembly around. The sensor is in the top corner, next to the cube ice seloniod.


59

Remove the sensor from under the clip, disconnect from the connector plug and replace. Reassemble in reverse order.

NOTE

To test the thermistors, check the temperature in the location of the thermistor. Use the chart on page C28 to test the thermistor for proper resistance at the temperature you are making your test at .

Food Compartment Light Switch

The food compartment light switch is installed in the top hinge cover. To remove the screws holding the hinge cover in place and lift the cover up. You can now remove the wires from the old switch and remove the switch form the cover. Reinstall in reverse order.

Freezer Compartment Light Switch

The freezer compartment light switch is installed in the top hinge cover. To remove the screws holding the hinge cover in place and lift the cover up. You can now remove the wires from the old switch and remove the switch form the cover. Reinstall in reverse order.

NOTE

This light switch is only controlling the freezer lighting. The dispenser switch is located in the freezer compartment on the left side and is controlled by the inner door panel on the freezer door contacting the actuator on the switch.

Section D - Air Circulation

Automatic Defrost Models

Principals Of Automatic Defrost

Operation

Automatic defrost refrigerators operate on the principle that moisture or frost transfers or migrates to the coldest surfaces (evaporator) in the freezer compartment. For example, a small amount of water spilled in the freezer compartment will freeze immediately. However, this ice in time will evaporate and transfer to the colder surfaces of the freezer evaporator coil.

Air Circulation Patterns

Automatic defrost models have a single evaporator in the freezer compartment, and have forced air cooling in the freezer and refrigerator compartments.

The “fin and tube” aluminum type evaporator is located behind the lower back wall of the freezer compartment. A circulating fan (suction type) pulls air from the freezer compartment through the grill in the bottom of the freezer and from the refrigerator compartment through a duct located in the separating wall in the bottom rear left hand corner of the cabinet interior. The air is than drawn up through the fin and tubes of the evaporator surface. The cold air is forced into a fan cover and discharged into the top of the freezer and out the air discharge under the ice maker. Figure D1. The air circulating fan operates any time the thermistors sense the temperature of the food compartment or the freezer compartment are above the upper control limit and send the information to the lower control board. If the food compartment is calling for cooling the automatic damper in the top of the food compartment will open and allow cold air to enter the food compartment. If the food compartment calls for cooling but the fan is not running, the fan will start is soon as the damper is open and will continue to run as long as the food compartment and/or the freezer compartment call for cooling.

The air circulating fan a 12 V DC fan motor operates any time the food compartment or the freezer compartment call for cooling. During the defrost period, the compressor and circulating fan do not operate. The power board located under the freezer behind the grill opens the electrical circuit to the fan motor and compressor for the defrost cycle.

The lower control board also closes the damper door that is controlled by a 12 V DC stepper motor and keeps the damper door closed during the complete defrost cycle.

NOTICE

Instructions given here are furnished as a guide.

Persons attempting to use these instructions to make repairs to the sealed refrigeration system should have a working knowledge of refrigeration and previous training on sealed system repair, and an EPA certification for servicing refrigeration systems.

IMPORTANT NOTICE

Effective July 1, 1992, the United States clean air act governs the disposal of refrigerants such as R-134a. Therefore, when discharging or purging the sealed system use an epa approved refrigerant recovery system as outlined in the final rule on the protection of stratospheric ozone and refrigerant recycling, which was published in the

Federal Register May 14, 1993.

NOTE

Frigidaire does not permit the use of recovered refrigerant in the servicing of our products for in-warranty and out-of-warranty repairs or for products covered by service contracts. Therefore, only new refrigerant or refrigerant that has been reclaimed back to new specifications by a refrigerant manufacturer is to be used.

Definitions

Recovery:

To remove refrigerant in any condition from a system and store it in an external container without necessarily testing or processing it in any way.

Recycling:

To clean refrigerant for reuse by oil separation and single or multiple passes through devices, such as replaceable core filter-driers, which reduce moisture, acidity and particulate matter.

This term usually applies to procedures implemented at the field job site or at a local service shop.

Reclaim:

To reprocess refrigerant to new product specifications by means which may include distillation. Will require chemical analysis of the refrigerant to determine that appropriate product specifications are met.

Safety Warnings

Compressor Testing

Whenever testing a compressor, extreme caution should be used to prevent damaging the terminals.

A compressor with a damaged terminal or a grounded winding can expel a terminal from its insulated housing when the compressor is energized. If this happens, a mixture of refrigerant and oil will be released that could be ignited by an external heat source (open flame, heater, etc.). Also, if there is air in the system when this happens, a spark at the compressor shell could ignite the refrigerant and oil mixture.

Charging Sealed Systems

Overcharging a refrigeration system with refrigerant can be dangerous. If the overcharge is sufficient to immerse the major parts of the motor and compressor in liquid refrigerant, a situation has been created which, when followed by a sequence of circumstances can lead to the compressor shell seam separating.

A hydraulic block occurs, preventing the compressor from starting. This condition is known as locked rotor. Electric current continues to flow through the compressor motor windings which become, in effect, electric resistance heaters.

The heat produced begins to vaporize the excess refrigerant liquid causing a rapid increase in system pressure. If the compressor protective devices fail, the pressure within the system may rise to extremes far in excess of the design limits.

Under these conditions, the weld seam around the compressor shell can separate with explosive force, spewing oil and refrigerant vapor which could ignite.

To eliminate this exceedingly rare but potential hazard, never add refrigerant to a sealed system. If refrigerant is required, evacuate the existing charge and recharge with the correct measured amount of the refrigerant specified for the system.

Soldering

WARNING

Wear approved safety glasses when working with or on any pressurized system or equipment. have an approved dry type fire extinguisher handy when using any type of gas operated torch.

1. All joints to be soldered must have proper fit. Clearance between tubes to be soldered should be from .001” to .006”. It is not practical to actually measure this; however, you do not want a dry fit or loose fit. Tubing joints should overlap about the distance of their diameter except for restrictor tubes, which should be inserted 1.25”.

2. Clean all joint areas with fine steel wool or preferably an abrasive cloth, such as grit cloth No. 23 or Scotch-Brite.

3. Apply a thin film of liquid flux recommended for silver soldering to surfaces to be joined and to surfaces immediately adjacent to joint.

4. Align tubing so no stress is on joint. Do not move tubing while solder is solidifying or leaks will result.

CAUTION

During application of heat, use wet cloths to prevent heat from conducting to areas other than the soldered joint. Use a sheet of metal or torch guard pad as a heat deflector to keep flame away from inflammable materials and painted surfaces.

5. Use a torch of adequate capacity so joint can be quickly heated with a minimum of heat travel to other points. Use a good grade of silver solder.

6. Solder connections. If tubing is properly cleaned and fluxed, solder will flow readily.

Use only enough solder to make a good bond.

7. Allow joint to cool, then wash exterior with water to remove flux.

Basic Components

The basic components of a refrigerator are a compressor, condenser, evaporator, heat exchanger (capillary tube and suction line), drier and perimeter hot tube.

Perimeter Hot Tube

To reduce the possibility of condensation forming on the exterior of the cabinet in high humidity areas, a perimeter hot tube (refrigerant tube) has been installed in the unit. The perimeter tube extends up the left side, across the top of the freezer and down the center mullion and into the filter drier. When the compressor operates, warm refrigerant flows through the primary condenser, then into the primary hot tube, warming the cabinet front exterior.

The perimeter hot tube is not replaceable. In the unlikely event of a leak in the hot tube, a kit is available to bypass the hot tube in the sealed system. A electrical heater wire must be installed within the tubing. Refer to the appropriate parts list of the model being serviced for the correct kit part number.

Refrigerant Cycle

The refrigerant cycle is a continuous cycle that occurs whenever the compressor is in operation.

Liquid refrigerant is evaporated in the evaporator by the heat that enters the cabinet through the insulated walls and by the heat from product load and door openings. The refrigerant vapor is then drawn from the evaporator, through the suction line to the compressor. Compression raises the pressure and temperature of the vapor in the compressor and the vapor is then forced through the discharge valve into the discharge line and into the condenser. Air passing over the condenser surface removes heat from the high pressure vapor which then condenses to a liquid. The liquid refrigerant then flows from the condenser to the evaporator through the small diameter liquid line

(capillary tube). Before it enters the evaporator, the liquid refrigerant is sub-cooled in the heat exchanger by the low temperature suction vapor in the suction line.

Low/High Side Leak or

Undercharge

A loss of refrigerant can result in any of the following:

1. Excessive or continuous compressor operation.

2. Above normal freezer and /or food compartment temperature.

3. A partially frosted evaporator (depending on


65

amount of refrigerant loss).

4. Low suction pressure (vacuum).

5. Low wattage.

The condenser will be “warm to cool”, depending on the amount of refrigerant lost.

When refrigerant is added, the frost pattern will improve, the suction and discharge pressures will rise, the condenser will become hot and the wattage will increase.

In the case of a low side refrigerant leak resulting in complete loss of refrigerant, the compressor will run but will not refrigerate. Suction pressure will drop below atmospheric pressure and air and moisture will be drawn into the system saturating the filter drier.

If there is reason to believe the system has operated for a considerable length of time with no refrigerant and the leak occurred in the low side of the system, excessive amounts of moisture may have entered the system. In such cases the two stage service Dryer Filter part number 5303918288 and vacuum procedure listed under Refrigerant

Leaks on page E 15 need to be followed to prevent repetitive service.

If a slight undercharge of refrigerant is indicated and no leak can be found after a thorough leak test, the charge can be corrected without changing the compressor.

If a high side leak is located and some refrigerant remains in the system it is not necessary to change the compressor.

Testing for Refrigerant Leaks

If the system is diagnosed as short of refrigerant and the system has not been recently opened, there is probably a leak in the system. Adding refrigerant without first locating and repairing the leak or replacing the component will not permanently correct the difficulty. The leak must be found. Sufficient refrigerant may have escaped to make it impossible to leak test effectively.

In such cases, add a ¼” line piercing valve to the compressor process tube. Add sufficient refrigerant vapor to increase the pressure to 40 to

50 lb. per sq. in. Check the low side for leaks. Run the compressor 2 or 3 minutes and check the high side for leaks. Recover refrigerant using an EPA approved recovery system.

NOTE

.

The line piercing valve (clamp-on type) should be used for test purposes only. It must be removed from system after it has served its purpose.

Checking for Internal (Hot

Tube) Leaks

Before checking for internal leaks, check all accessible system components and joints for leaks.

If an internal hot tube leak is suspected, it must be confirmed. Use the following procedure:

1. Recover refrigerant by using EPA approved recovery system.

2. After system refrigerant is completely recovered, disconnect drier from hot tube.

Pinch off and solder end of hot tube closed.

3. Cut line from condenser to hot tube and solder a ¼”charging hose fitting to open end of hot tube or put compression fitting on tube.

4. Connect pressure gauge and access valve to hot tube and pressurize to 250 psig using dry nitrogen or carbon dioxide.

WARNING

Never pressurize with oxygen. never open a high pressure tank unless it is equipped with a pressure regulator. never put high pressure on dome of compressor – it could explode. make sure gauge, HOSES, AND ALL fittings are in good condition and do not leak.

5. Leave pressure on hot tube for 24 hours. Any drop in pressure is indication of leak.

If dry nitrogen or carbon dioxide is not available, follow steps 1 through 3 above, then steps 4 and 5 below:

4. Connect gauges to charging hose fittings.

Pull vacuum on hot tube.

5. Leave vacuum on each side of system for 24 hours. Any loss of vacuum indicates leak.

66


Compressor Replacement

CAUTION

NEVER install a new compressor without first checking for possible system contamination.

To check for contamination, obtain oil sample from old compressor.

• If the oil has burned odor, but no color change or residue — follow instructions in section “Installing A New Compressor”.

• If oil has a burned odor and a sugar or gritty feel as well as showing signs of contamination (dark color) — follow instructions in next section, To Flush The

System. Remove as much of contamination as possible from system before installing new compressor and filter-drier.

To Flush The System

NOTE

It is recommended that system be flushed with dry Nitrogen. However, if refrigerant is used to flush the system you must look at the serial plate to see what type of refrigerant is used in the system. This is the only refrigerant that can be used to flush the system and it must be recovered.

CAUTION

Use extreme care when using Dry

Nitrogen to flush systems. Pressure in nitrogen cylinder could be as high as 2000 psi. Nitrogen cylinder must be equipped with approved pressure regulator and pressure relief valve.

Ensure that your hoses have adequate ratings for pressure involved and that all of your equipment is in good condition.

The end of the flushing hose on this tank regulator must be equipped with a hand shut-off valve (Robinair No. 40380). Close hand shut-off valve and adjust nitrogen regulator to correct pressure before proceeding with flushing procedure.

To Use Dry Nitrogen To Flush The System:

1. Remove compressor and filter-drier. Connect process coupling to outlet tube of condenser.

2. Fasten cloth over other end of coil to prevent old oil from spraying over room.

3. Connect hand shut-off valve on flushing hose to process coupling.

4. Slowly open hand shut-off valve and allow nitrogen to flow through condenser until discharge is clear.

CAUTION

DO NOT exceed 300 PSIG.

5. Disconnect cap tube from evaporator. Flush evaporator in same manner as condenser.

CAUTION


6. Flush cap tube. This is only possible if you have proper service valve adaptor.

CAUTION


7. Reassemble system.

To Use Refrigerant To Flush The System:

CAUTION

Refrigerant used for flushing must be recovered into a recovery system. Meter amount of refrigerant used for flushing with your charging cylinder. DO NOT OVERFILL

THESYSTEM.

1. Disconnect the suction and discharge lines from the compressor and remove the filterdrier. Connect process coupling to outlet and inlet tube of condenser.

2. Connect hose to outlet process coupling and charging cylinder. Connect another hose to inlet coupling and recovery system.

3. Open charging cylinder and allow refrigerant to flow through condenser until discharge into bag is clear.


67

NOTE

To flush evaporator and heat exchanger you must remove evaporator from inside product to disconnect cap tube.

4. Disconnect capillary tube from evaporator.

Flush evaporator in same manner as condenser.

5. Flush cap tube. This is only possible if you have proper service valve adaptor.

6. Reassemble system.

Installing a New Compressor

NOTE

Entirely new compressors have been developed for use with R-134a and Ester oil refrigeration systems. Both compressor and electric motor have been modified. Old compressors intended for R-12 refrigerant must not be used for new systems charged with R-134a.

Replacement of compressor and installation of filter-drier must be done in a continuous sequence so system is exposed to atmosphere no longer than necessary.

All replacement compressors are shipped with rubber plugs in the suction, discharge and process tubes and contain the correct oil charge and a holding charge of inert gas. Compressors have a low-side process tube attached to the compressor shell. A high-side process tube is attached to the filter-drier.

WARNING

Do not operate reciprocating compressor when charging liquid refrigerant into system through its process tube.

CAUTION

DO NOT use compressor if you do not hear this sound.

If the compressor checks OK, reinstall the plug.

Do not remove any of the plugs again until the compressor is in position and you are ready to braze the lines.

CAUTION

On R-134a systems, compressor must NOT be left open to atmosphere for more than 10 minutes to prevent moisture contamination of oil.

A new compressor which is cold (e.g. after having been kept in a cold service van) should be left to warm to the surrounding temperature before the plugs on the compressor connections are removed.

This will help prevent condensation from forming in the oil and the compressor. Also, avoid opening the system when any of the components or lines are cold.

NOTE

Release holding charge (release slowly to avoid oil discharge) on new compressor to ensure there is no leak in seam or tubing. Reinstall rubber plug.


2. Remove compressor access panel.


4. Remove condenser fan mounting screws.

5. Unplug fan motor harness located in back of fan motor.

6. Remove fan motor and fan blade.

7. Remove leads from compressor motor terminals.

8. Remove mounting clips and washers.

Replacement compressors for refrigerator may have an oil cooler even if the original compressor did not. If the product is not equipped for an oil cooler, leave the plastic caps in place and install the compressor connecting only to the suction and discharge lines of the new compressor.

Before installing the replacement compressor remove the discharge plug and check for the pop sound of the inert gas leaving the compressor.

68


Figure E1

9. After refrigerant is completely recovered, cut suction and discharge lines as close to compressor as possible. Leave only enough tubing to pinch off and seal defective compressor. Plug or tape any open system tubing to avoid entrance of moisture and air into system. Remove inoperable compressor and transfer mounting parts to new compressor.

10. Install new compressor in exact same manner as original compressor.

11. Reform both suction and discharge lines to align with new compressor. If they are too short, use additional lengths of tubing. Joints should overlap 0.5” to provide sufficient area for good solder joint. Clean and mark area where tubing should be cut . Cut tubing with tubing cutter. Work as quickly as possible to avoid letting moisture and air into system.

NOTE

If low-side process tube is too short, silver solder four inch piece of tubing onto process tube at this time.

12. Solder all connections according to soldering procedure.

13. Remove original filter-drier.

CAUTION

DO NOT unbraze old filter-drier from system.

This will vaporize and drive moisture from desiccant back into system. The old filter-drier should be cut out of system.

14. Install new filter-drier at condenser outlet.

15. Evacuate and charge system using recommended procedure described under

Evacuating and Recharging.

16. Reconnect compressor terminal leads in accordance with refrigerator wiring diagram.

17. Reassemble unit.


69

Evaporator Replacement

CAUTION

Always use the TORCH GUARD heat shield part number 5304418872, behind evaporator before attempting to solder. The excessive heat from soldering will warp the plastic liner.

The evaporator is located in the lower section of the freezer and is secured to the drain pan by a bracket at the top. Styrofoam blocks are located on each side, directly across from each other to ensure proper air flow through the evaporator.

The heat exchanger on this style of refrigerator is in the insulation between the food liner and the cabinet back. You will not be able to remove the heat exchanger with the evaporator. Because of this, all line welds will be made inside the freezer.

The evaporator kit contains a heat shield to protect the liner from damage when brazing.

13. Install new filter-drier at condenser outlet.

14. Evacuate and charge the system using recommended procedure described under



Filter-Drier Installation

Any time the sealed system is opened and the refrigerant charge is removed, the liquid line filterdrier must be replaced and the system thoroughly evacuated before recharging.

CAUTION

DO NOT unbraze the old filter-drier from the system. This will vaporize and drive moisture from the desiccant back into the system. The old filter-drier should be cut out of the system.

CAUTION

Use only a 15 gram XH9 liquid line filter-drier

(part number 5303305677) when servicing refrigerator and freezer systems. This filterdrier is compatible with either R-12 or R-134a refrigerant.

1. Disconnect unit from source of power.

2. Recover refrigerant by using an EPA approved recovery system.

3. Using a 3 cornered file, score a groove around capillary tube as close to old filterdrier as possible. Break capillary tube along score mark from filter-drier.

4. Cut condenser outlet tube at filter-drier.

Discard filter-drier.

5. Thoroughly clean condenser outlet tube and capillary tube.

6. Place inlet connection of filter-drier over condenser tube approximately ¼” and solder.

7. Insert capillary tube input end into filter-drier outlet. Do not allow tube to bottom against screen. Solder carefully so that solder does not plug capillary tube.

8. Install process tube adaptor to filter-drier.

9. Evacuate and charge system using the recommended procedure described under



Evacuating and Recharging

CAUTION

Check the serial plate for the correct refrigerant type. It is extremely important to verify the type of refrigerant in the system before starting any sealed system repairs.

With the possible exception of the vacuum pump, all service equipment that comes in contact with R-134a during evacuation and recharging must be dedicated. Accordingly,

R-134a will require a dedicated charging cylinder, manifold gauge set, process tube adaptors, and hoses. Any residual mineral oil on other tools (tubing cutter, etc.) must be thoroughly cleaned off before using on R-134a/Ester oil systems. It will be necessary to check with the manufacturer of your vacuum pump for refrigerant and oil compatibility issues.

If you use a vacuum pump with mineral oil to evacuate an R-134a system, it is

ABSOLUTELY ESSENTIAL to have a shut-off valve between the pump and your manifold gauge set as shown on page Figure E2. The hand valve must be closed during all times when the vacuum pump is not operating. This will prevent the migration of mineral oil vapor into the R134a/Ester oil system. If the vacuum pump should stop during evacuation for any reason, the hand pump shut-off valve must be closed immediately.

Insure that your refrigeration hoses are specified for use with R-134a refrigerant.

Research has shown that compounds in standard refrigeration hoses may enter sealed systems and ultimately restrict the cap tube in an R-134a system.

Installing Evacuation and Recharging

Equipment


2. If compressor was replaced, install correct sized process tube adaptor on process tube.

If compressor was not replaced, cut process tube with tubing cutter leaving as much tube as possible and install correct size process tube adaptor.

3. Install correct sized process tube adaptor on high-side process tube.

4. Attach refrigeration service gauge manifold to system in following order:

• Low-side (compound gauge) hose to suction side process tube adaptor.

• High-side (pressure gauge) hose to high-side process tube adaptor.

• Center port manifold hose before hand shutoff valve to charging cylinder.

• Center port manifold hose after hand shut-off valve to vacuum pump.

Evacuating System

WARNING

R-134a systems are particularly susceptible to moisture contamination which can only be prevented by evacuating the system for a minimum of 30 minutes to attain a minimum

29.9 inch (500 micron or lower) vacuum.

To achieve the required levels of evacuation, a properly maintained two stage vacuum pump in good condition is required. It is absolutely essential to maintain your vacuum pump according to the manufacturer’s instructions including required oil changes at the recommended intervals.

Vacuum pump oil should always be changed after evacuating a contaminated system.

Vacuum pump performance should be checked periodically with a micron gauge.

1. Make certain that charging cylinder valve, hand shut-off valve, and manifold gauge valves are closed.

2. Start vacuum pump.

3. Open hand shut-off valve and slowly open both manifold valves, turning counterclockwise, for two full rotations.

CAUTION

If high vacuum equipment is used, just crack both manifold valves for a few minutes and then open slowly for the two full turns counterclockwise. This will prevent the compressor oil from foaming and being drawn into the vacuum pump.

4. Operate the vacuum pump for a minimum of 30 minutes to a minimum of 29.9” (500 micron) vacuum.

NOTE

On products with Low side leaks you must heat the crankcase area of the compressor though out the 30 minutes you are running your vacuum pump to pull a vacuum on the system. Every 4 to 5 minutes while you are running your vacuum pump and heating the crankcase area shake the compressor. By heating the crankcase you are heating the oil in the compressor. This will drive the moisture out of the oil. By shaking the compressor this will allow the moisture to come to the top of the oil faster so the vacuum pump can remove the moisture from the system.

76


5. Close hand shut-off valve to vacuum pump.

Watch compound gauge for several minutes.

If reading rises, there is a leak in the system, go to step 6. If no leak is indicated, stop vacuum pump. System is now ready for charging.

6. If a leak is indicated, stop vacuum pump and introduce a small charge of refrigerant into system by cracking valve on bottom of charging cylinder until system is pressurized to 40 or 50 lbs psig.

7. Leak test low-side. Close compound gauge.

Run compressor for a few minutes and leak test high-side. When leak is found, recapture refrigerant using EPA approved recovery system Repair and go back to step 1.

Charging The System

CAUTION

Check the serial plate for the correct refrigerant type. It is extremely important to verify the type of refrigerant in the system before starting any sealed system repairs.

After charging the system with liquid be certain to wait at least 5 minutes before starting the compressor to give the refrigerant a chance to disperse throughout the system.

Otherwise the compressor could be damaged by attempting to pump excessive quantities of liquid.

Preparing The Charging Cylinder:

1. Make certain that hand shut-off valve to vacuum pump is closed.

2. Close high-side manifold gauge valve.

3. Set charging cylinder scale to pressure indicated on cylinder pressure gauge.

4. Observe refrigerant level in sight glass.

Subtract amount to be charged into system and note shut off point.

5. Open charging cylinder valve slowly and allow proper charge to enter system.

6. As soon as refrigerant in sight glass has gone down to predetermined level, close charging cylinder valve.

WARNING

Disconnect the charging cylinder heater at this time to prevent the cylinder pressure from exceeding its maximum limits.

7. Allow system to sit for five minutes.

8. Turn on refrigerator compressor. Run compressor for a few minutes and monitor system pressures.

9. When satisfied that the unit is operating correctly, clamp the high-side process tube with the pinch-off tool while the unit is still running.

10. Slowly open the high-side manifold gauge valve to allow the compressor to remove any refrigerant trapped in the high-side hose and the process fitting.

11. Close both of the manifold gauge valves. If the high-side gauge reading rises, the pinchoff must be corrected before proceeding.

12. Remove the high-side process tube adaptor and solder the process tube closed.

13. Clamp the low-side process tube with the pinch-off tool while the unit is running.

Remove the low-side process tube adaptor and solder the process tube closed.

14. Check the process tubes for refrigerant leaks.

NOTE

Process valves are not to be left on the tubing in any application, except the valve on EMA Service drier part # 5303918288.

Final Leak Test

1. With the refrigerator turned OFF leak test all low-side system components.

2. Turn the unit ON and run until the condenser is warm. Leak test the high-side system components.

Section E - R-134a Service Information

NOTICE

Instructions given here are furnished as a guide.

Persons attempting to use these instructions to make repairs to the sealed refrigeration system should have a working knowledge of refrigeration and previous training on sealed system repair.

Verify Refrigerant Type In The

System

CAUTION

R-134a and R-12 are completely incompatible.

Before starting any sealed system repair, it is extremely important to check serial plate of product to verify the type of refrigerant in the system.

Dedicated Equipment

R-134a must not be mixed with other types of refrigerants. R-134a must be recovered in dedicated and properly identified recovery bags and tanks.

It will be necessary to check with the manufacturer of your recovery equipment to determine

R-134a compatibility. Some recovery equipment manufacturers have changeover instructions for switching between refrigerant types. Protect yourself and your equipment by following all manufacturer guidelines.

Also, ensure that your refrigeration hoses are specified for use with R-134a refrigerant.

Research has shown that compounds in standard refrigeration hoses may enter sealed systems and ultimately restrict the cap tube in an R-134a system.

R-134a Refrigeration Systems

The sealed refrigeration system will consist of the same basic components being utilized in the R-12 systems.

There is a 10% to 15% discharge pressure increase using R-134a, with a 5% to 10% decrease in suction pressure when compared to the same product with an R-12 system operating at 90°F

(32°C) ambient temperature conditions. Lower suction pressures result from the lower density of

R-134a refrigerant which effects refrigerant flow rate. R-134a systems commonly operate in a 1”-2” vacuum on the suction side.

Products using R-134a refrigerant will generally have a longer capillary tube to maintain a similar flow rate and some models will have a larger condenser to reduce the discharge pressures and lower start-up sound transmission.

Miscibility of R-134a and

Ester Oil

A special synthetic oil known as Ester oil is used as a lubricant in refrigeration systems operating on R-134a. Ester oils are produced from alcohols and fatty acids and are available in several different variants. Ester oils have a pleasant aroma reminiscent of fruit.

Ester oils generally include various types of additives for improving certain properties such as viscosity, temperature sensitivity, etc. These additives are often aggressive, and skin contact with Ester oils should therefore be avoided.

One of the most important requirements made on a refrigerant system is that the oil mix with the refrigerant. Since mineral oil and ordinary synthetic oil DO NOT mix with R-134a, Ester oil is used for lubrication. Ester oil dissolves in R-134a.

Ester oil is broken down by chlorine and cannot be used with R-12 (R-12 contains chlorine) or any other compound containing chlorine. Therefore,

R-134a refrigeration systems have virtually no tolerance for chlorine molecules from CFC refrigerants (R-134a is an HFC and contains no chlorine).

CAUTION

During R-134a service, it is extremely important to avoid using equipment that may contain residual amounts of mineral oil, CFC’s or HCFC’s which could enter and contaminate the sealed system.

For example, hoses that were used for a refrigeration system operating on R-12 may contain small quantities of mineral oil which can block the capillary tube in a system operating on R-134a. As little as one milligram may be sufficient to cause a blockage. In addition, sealed system components that have been used with CFC systems must not be used with R-134a systems. These components may contain residual amounts of refrigerant and oil which could damage an R-134a system.


79

At the earliest stage of development work on

R-134a, tests were carried out on a different type of synthetic oil known as Poly-Alkaline Glycol (PAG).

This oil is also used in certain air conditioning systems for cars. PAG and Ester oil DO NOT mix with one another. Service equipment used for

R-134a / Ester oil must not come into contact with

PAG.

Water In The Refrigeration

System

Even in very small quantities, water in any refrigeration system can cause the following problems:

• Ice plugs in capillary tubes.

• Copper plating in compressor.

• Reactions with organic materials in systems.

• Corrosion of metals.

R-134a and Ester oil will aggravate the problem of water in the refrigeration system. Ester oil may react with water vapor and is hydroscopic (it will absorb water if it comes in contact with humid air).

Water is also more soluble in R-134a than R-12.

To minimize the water content whenever service work is performed, the refrigeration system should always be thoroughly evacuated through process tube adaptors on both the high and low sides of the system. Evacuation must be for a minimum of 30 minutes to at least a 29.9 inch (500 micron) vacuum.

To achieve the required 29.9 inch (500 micron) vacuum, a properly maintained two-stage vacuum pump in good condition is required. A two stage pump can reach a deeper vacuum than a single stage because the exhaust from the first pumping stage is discharged into the second pumping stage.

This means the second stage begins pumping at a lower pressure so a lower ultimate vacuum can be achieved (See 2-Stage Vacuum Pump, Figure E3).

Vacuum Pump Maintenance

It is absolutely essential to maintain your vacuum pump according to the manufacturer’s instructions including required oil changes at the recommended intervals. Vacuum pump oil should always be changed after evacuating a contaminated system.

Vacuum pump performance should be checked periodically with a micron gauge.

Vacuum pump suppliers may or may not recommend changing the vacuum pump oil to the same type that’s in the system being evacuated.

Some manufacturers may recommend a vacuum pump that’s dedicated to R-134a systems.

Robinair has stated that their current and discontinued vacuum pump models, using mineral oil currently specified for use in their vacuum pumps, can be used to evacuate R-134a/Ester oil systems. Robinair also states that it is acceptable to alternate between evacuating R-12/mineral oil and R-134a/Ester oil systems without adversely effecting the vacuum pump’s performance.

For other brands of vacuum pumps, check with the manufacturer for restrictions and guidelines when using with R-134a.

80


CAUTION

If you use a vacuum pump with mineral oil to evacuate an R-134a system, it is ABSOLUTELY

ESSENTIAL to have a shut-off valve between pump and your manifold gauge set as shown in Figure E2. The hand valve must be closed during all times when vacuum pump is not operating. This will prevent migration of mineral oil vapor into R134a/Ester oil system. If vacuum pump should stop during evacuation for any reason, the hand pump shut-off valve must be closed immediately.

Refrigerant Leaks

A system with R-134a and Ester oil will become saturated with moisture much faster than a system with R-12 and mineral oil. If your leak was in the low side of the refrigeration system when the compressor is running the pressure in the low side will go into a vacuum. As additional refrigerant leaks out the system will go deeper into a vacuum.

The system running in this vacuum will allow air and moisture to be pulled into the sealed system.

The moisture pulled in can then be mixed in to the

Ester oil in the compressor.

If the product has had a low side leak you will need to install the two stage service dryer filter part number 5303918288. You must heat the crankcase area of the compressor using a heat gun on the high heat setting though out the 30 minutes you are running your vacuum pump to pull a vacuum on the system. Every 4 to 5 minutes while you are running your vacuum pump and heating the crankcase area shake the compressor. By heating the crankcase you are heating the oil in the compressor. This will drive the moisture out of the oil. By shaking the compressor this will allow the moisture to come to the top of the oil faster so the vacuum pump can remove the moisture from the system.

Electrolux Home products does not approve the use of the Sweep Charge for sealed system

repair. This method of servicing sealed systems we know is often used to repair products in the field. The Sweep Charge does not adequately remove the moisture from the oil in the compressor .

In a R-134a system you will need to replaced the compressor if the product has had a low side leak and you are servicing with the Sweep Charge procedure.

R-134a refrigerant molecules are smaller than

R-12 molecules. This means that R-134a will pass more minor leaks and the rate of flow will be greater than for R-12. Therefore, it is now more important than ever to follow good brazing practices. Use a good grade of silver solder. 45% silver solder is recommended.

Leak Detection

R-134a system leaks can be pinpointed by means of an electronic leak detector or by bubble solution.

Electronic leak detectors for R-134a service are currently available from several manufacturers. The least expensive models are non-selective detectors that will detect any type of emission or vapor present, regardless of its chemical composition. Some nonselective detectors designed for use with R-12 may have a much lower sensitivity when used with

R-134a. However, newly designed detectors with good R-134a sensitivity are now available. Be sure to consult with the manufacturer before selecting or using a non-selective detector with R-134a.

Halogen-specific detectors use a specialized sensor that allows detection of compounds containing chlorine, fluorine, bromine, and iodine without being activiated by other species. The major advantage of this type of detector is a reduction in the number of “nuisance alarms”. Halogen-specific detectors are generally more expensive than non-selective detectors but feature higher sensitivity.

R-134a Health & Safety Information

Inhalation Toxicity

HFC-134a poses no acute or chronic hazard when it is handled in accordance with DuPont recommendations and when exposures are maintained at or below the DuPont Acceptable

Exposure Limit (AEL) of 1,000 ppm (8 and 12 hour

Time-Weighted Average or TWA).

An AEL is an airborne exposure limit established by DuPont scientists that specifies time-weighted average (TWA) airborne concentrations to which nearly all workers may be repeatedly exposed without adverse effects. The AEL for HFC-134a has the same value as the Threshold Limit Values

(TLVs) established for CFC-12 and HCFC-22. TLVs are established by the American Conference of

Governmental and Industrial Hygienists (ACGIH).

However, inhaling high concentrations of HFC-

134a vapor may cause temporary central nervous system depression with narcosis, lethargy and anesthetic effects. Other effects that may occur include dizziness, a feeling of intoxication and a loss of coordination. Continued breathing of high concentrations of HFC-134a vapors may produce cardiac irregularities (cardiac sensitization), unconsciousness, and with gross overexposure, death. Intentional misuse or deliberate inhalation of

HFC-134a may cause death without warning. This practice is

extremely dangerous.

If you experience any of the initial symptoms, move to fresh air and seek medical attention.

Cardiac Sensitization

If vapors are inhaled at a concentration of 75,000 ppm, which is well above the AEL, the heart may become sensitized to adrenaline, leading to cardiac irregularities and, possibly, to cardiac arrest. The likelihood of these cardiac problems increases if you are under physical or emotional stress.

Medical attention must be given immediately if exposed to high concentrations of HFC-134a.

DO NOT treat with adrenaline (epinephrine) or similar drugs. These drugs may increase the risk of cardiac arrhythmias and cardiac arrest. If the person is having difficulty breathing, administer oxygen. If breathing has stopped, give artificial respiration.

Spills or Leaks

If a large release of vapor occurs, such as from a large spill or leak, the vapors may concentrate near the floor or low spots and displace the oxygen available for breathing, causing suffocation.

Evacuate everyone until the area has been ventilated. Use blowers or fans to circulate the air at floor level. DO NOT reenter the affected area unless you are equipped with a selfcontained breathing apparatus or unless an area monitor indicates that the concentration of

HFC-134a vapors in the area is below the AEL.

Always use self-contained breathing apparatus or an air-line mask when entering tanks or other areas where vapors might exist. Use the buddy system and a lifeline. Refer to the Material Safety Data

Sheet (MSDS) for HFC-134a for more information.

HFC-134a vapors have a slightly sweet odor that can be difficult to detect. Therefore, frequent leak checks and the installation of permanent area monitors may be necessary in enclosed spaces.

Refer to ASHRAE Standards 15 and 34 for refrigeration machinery rooms.

To ensure safety when working with HFC-134a in enclosed areas:

1. Route relief and purge vent piping (if present) outdoors, away from air intakes.

2. Make certain area is well ventilated, using auxiliary ventilation, if necessary, to move vapors.

3. Make sure area is clear of vapors prior to beginning work.

4. Install air monitoring equipment to detect leaks.

Skin and Eye Contact

At room temperature, HFC-134a vapors have little or no effect on the skin or eyes. However, in liquid form, HFC-134a can freeze skin or eyes on contact, causing frostbite. Following contact, soak the exposed area in lukewarm water, not cold or hot. If medical treatment cannot begin immediately, apply a light coat of a nonmedicated ointment, such as petroleum jelly. If the exposed area is in a location where the presence of the ointment would be awkward, such as on the eye, apply a light bandage. In all cases of frostbite, seek medical attention as soon as possible.

R-134a Health & Safety Information

83

Always wear protective clothing when there is a risk of exposure to liquid HFC-134a. Where splashing is possible,

always wear eye protection and a face shield.

Combustibility of HFC-134a

HFC-134a is nonflammable at ambient temperatures and atmospheric pressure. However, tests have shown HFC-134a to be combustible at pressures as low as 5.5 psig (139.3 kPa absolute) at 177°C (350°F) when mixed with air at concentrations generally greater than 60% volume air. At lower temperatures, higher pressures are required for combustibility. (HCFC-22 is also combustible at pressures above atmospheric in the presence of high air concentrations). Test results and calculations have shown:

• At ambient temperature, all concentrations of HFC-134a in air are nonflammable at pressures below 15 psig (205 kPa absolute).

• Combustible mixtures of air and HFC-

134a will not form when liquid HFC-134a is pumped into closed vessel if initial air pressure in vessel is limited to one atmosphere absolute and final pressure is limited to 300 psig (2,170 kPa absolute).

If initial air pressure is greater than one atmosphere, combustible mixtures may form as tank is filled.

Based on above information, the following operating practices are recommended:

Leak Testing

• Equipment should

NEVER be leak tested with a pressurized mixture of HFC-134a and air. HFC-134a may be safely pressured with dry nitrogen.

Bulk Delivery and Storage

• Tanks should normally be evacuated at start of filling, and should never be filled while under positive air pressure.

• Tank pressure should never be allowed to exceed 300 psig (2,170 kPa) when filling with

HFC-134a. Relief devices on either tanks or HFC-134a supply system usually prevent this.

• Tank pressures should be monitored routinely.

• Air lines should never be connected to storage tanks.

Filling and Charging Operations

• Before evacuating cylinders or refrigeration equipment, any remaining refrigerant should be removed by recovery system.

• Vacuum pump discharge lines should be free of restrictions that could increase discharge pressures above 15 psig (205 kPa) and result in formation of combustible mixtures.

• Cylinders or refrigeration equipment should normally be evacuated at start of filling,and should never be filled while under positive air pressure.

• Final pressures should not exceed 300 psig

(2,170 kPa).

• Filled cylinders should periodically be analyzed for air (nonabsorbable gas or NAG).

Refrigerant Recovery Systems

Efficient recovery of refrigerant from equipment or containers requires evacuation at the end of the recovery cycle. Suction lines to a recovery compressor should be periodically checked for leaks to prevent compressing air into the recovery cylinder during evacuation. In addition, the recovery cylinder pressure should be monitored, and evacuation stopped in the event of a rapid pressure rise indicating the presence of noncondensable air. The recovery cylinder contents should then be analyzed for NAG, and the recovery system leak checked if air is present. DO NOT continue to evacuate a refrigeration system that has a major leak.

Thermal Decomposition

HFC-134a vapors will decompose when exposed to high temperatures from flames or electric resistance heaters. Decomposition may produce toxic and irritating compounds, such as hydrogen fluoride. The pungent odors released will irritate the nose and throat and generally force people to evacuate the area. Therefore, it is important to prevent decomposition by avoiding exposure to high temperatures.

84

Section F - Ice Maker

Rear Mounted Ice Maker

The automatic ice maker is mounted in the freezer compartment. It is attached to a bracket extending up from the back of the auger motor cover.

The Ice Maker is designed to produce ice automatically. The length of time between harvest cycles will vary, depending on load conditions, door openings, ambient temperature and freezer temperature and water temperature. These factors must be taken into consideration when checking the ice production rate.

With a temperature of -2°F to +5°F in the freezer, the rate of harvest will be 40 to 96 cubes per 24 hour period.

The ice maker is wired across the line and will harvest ice in the refrigeration or defrost cycles.

The water valve and solenoid assembly are both mounted in the compressor compartment.

A tube extends from the water valve up the rear wall of the refrigerator to a water inlet spout that directs the water into the fill trough. The water fill spout will twist lock into a housing in the back of the refrigerator and direct water flow into the ice maker from the side of the mold.

Front Cover (Figure F4)

A decorative front cover, made of molded plastic, encloses the operating mechanism of the ice maker, protecting it from moisture. It is essential that the cover be in place on an operating ice maker to protect against possible contact with the mechanism by the user. (See Figure F1)

ice maker Components

Ice Mold (Figure F5)

The ice mold is die-cast aluminum with the ice maker thermostat bonded to its front surface. The mold has a semi-circular interior partitioned into equal size compartments. Water enters at the side of the mold, through a fill trough. A film of silicon grease on the top edge of the mold prevents siphoning of water by capillary action.

Mold Heater (Figure F6)

A mold heater, rated at 112 watts at 115volts, ? ohms ± 10% it is covered with an aluminum sheath and embedded in the grooved section on the underside of the Ice Mold. When the mold heater is energized, the ice contact surface within the mold is heated enough to allow harvest of the ice pieces.

The mold heater is wired in series with the Ice

Maker thermostat, which acts as a safety device.

The heater is staked in place, and is replaced as part of the ice maker Mold.

A thermal mastic sealer is placed between the heater and the mold to ensure good thermal contact.

Ice Stripper (Figure F5)

A Ice Stripper is attached to the mold to prevent ice pieces from falling back into the mold. It also serves as a decorative side cover.

Ice Ejector (Figure F5)

The Ejector blades are molded from delrin, and extend from a central shaft, which turns in nylon bearings at the front and rear. Each blade sweeps an ice section out of the mold. The drive end of the Ice ejector is “D” shaped. Food Grade Silicone grease is used to lubricate the bearing surfaces.

Water Valve Assembly

The water valves are solenoid operated and when energized, releases water from the water tank in the foood compartment into the Ice Mold. The amount of water released is directly proportional to the length of time the water valve Switch is energized. A flow washer, inside the water valve, maintains a constant rate of water flow over a supply line with pressure ranging from 20 to 100 psig. It will not compensate for pressures below

20 psig, or greater than 100 psig. A No. 80-mesh screen, placed ahead of the flow washer, filters out foreign materials.


85

The solenoid coil draws 10 to 20 watts of power.

The coil is wired in series with the mold heater, across the supply voltage.

Thermostat (Figure F6)

The thermostat is a single-pole, single throw

(SPST), bimetallic, disk-type, thermal switch. It automatically starts the harvest cycle when the ice is frozen. The thermostat closes at a temperature of 9°F ± 2°. Wired in series with the mold heater, the thermostat acts as a safety device against overheating in the event of mechanical failure.

A thermal mastic bond is provided where the thermostat is mounted against the mold. A gasket prevents water from leaking into the support housing.

Sensing Arm & Linkage (Figure F5 &

F6)

The sensing arm is cam-driven and operates a switch that controls the quantity of ice produced. In the harvest Cycle, the arm is raised and lowered during each of the two revolutions of the timing cam. If the sensing arm comes to rest on top of ice in the storage compartment during either revolution, the switch will remain open and stop the ice maker at the end of that revolution. When sufficient ice is removed from the storage container, the sensing arm lowers and ice production resumes. To manually stop the ice maker turn the switch located on the housing at the left end of the icemaker to off. Operation is resumed when the switch is turned back to on.

Timing Switches (See Figure F2)

The three timing switches used are single- pole, double throw (SPDT). They are identical except for function, and can be used interchangeably.

1. Hold Switch - assures completion of a revolution once the ice maker operation has started.

2.

Water Fill Switch - opens the water valve during the fill cycle. It is the only adjustable component in the ice maker.

3. Shut-Off Switch - stops ice maker operation when the storage container is full of Ice. The switch is opened after the sensing arm is raised to its most upright position. The switch is mounted to the top right wall of the ice maker support. (Not shown in Figure F6)

Thermal Cut-Out (TCO)

The thermal cut-out is a one-time limit fuse used as a safety device. It is located under the mounting plate, in the head of the ice maker, between the thermostat and wire connector.

If the thermal cut-out opens, the cause of failure must be determined and corrected prior to replacing the TCO. Normals causes of the TCO failing are a bad thermostat or a shorted coil on the water valve.

Timing Cam & Coupler

Three separate cams are combined in one molded

Delrin part:

1. Inner cam operates shut-off switch lever arm.

2. Center cam operates hold switch.

3. Outer cam operates water fill switch.

One cam end is attached to a large timing gear.

The other cam end is coupled to the ejector.

Timing Gear (Figure F1)

This large molded plastic gear is driven by the motor and, in turn, rotates the cam and ejector.

A “D” shaped hole in the gear fits over the timing cam hub. Spacer tabs on the backside of the gear prevent the gear from binding on the mounting plate.

Motor (Figure F2)

A low wattage, stall-type motor drives the timing gear. This gear turns the timing cam and ejector blades approximately one revolution every three minute (1/3 RPM).

86


On/Off Switch (Figure F5 & 6)

A single-pole, single-throw switch is mounted on the right side of the housing at the front of the ice maker. This switch is used to turn the ice maker off.

Unlike the switch on the bail arm the on/off switch will stop the ice maker as soon as it is pushed, and it will not allow the ice maker to complete the revolution.

Wiring

A four-prong plug connects the ice maker wiring to the cabinet wiring harness. (See Figure F3.) The ice maker assembly is wired across the line and will harvest in either the refrigeration or defrost cycles.

A wiring diagram is located inside the front cover of the ice maker.

Installing Water Supply Line to Ice Maker

Supply line installation must comply with all applicable plumbing codes. Refer to the

Ice Maker

Installation Instructions in appendix A.

The ¼” tubing, and any other plumbing materials required, should be obtained locally.

The ice maker should be connected to a frequently used cold water line to ensure a fresh water supply.

NOTE

A vertical cold water line should be selected for the water supply. If a vertical line is not available, a horizontal line may be used, providing the connection is on the side or top of the pipe, but

not on the bottom. Scale and foreign material in the pipe could cause stoppage of water flow if the connection is on the bottom.

Be sure to leak test all connections after the water supply has been turned on.

Test Cycling Ice Maker

(See Ice

Maker Testing Procedures.

It may be necessary, on occasion, to test-cycle an ice maker to check its operation. This can be done on the repair bench or while mounted in the refrigerator.

If the ice maker is in an operating refrigerator, take precautions against the formation of condensate by allowing the cold, metal components to warm up before removing the front cover. This can be expedited by cycling the assembly with the cover in place and the water supply valve closed.

To manually cycle the ice maker, push the on off switch to the on position then push in harder against the spring loaded second set of contacts in the switch and hold in until the hold switch circuit to the motor is completed. When the motor starts, all components except the ice maker thermostat should perform normally. Once the ice maker completes its cycle, if additional testing is necessary you can you can push in on the switch again to start the icemaker into another cycle.

Water Valve Switch – Water

Fill Volume

The amount of water fill is directly proportional to the length of time terminals “C-NC” of the water fill switch are closed. Closing occurs when the switch plunger drops into a cavity formed in the cam.

Different water valves have different flow rates. For this reason, anytime a water valve is replaced, the water fill must be checked and the fill switch must be adjusted if needed.

The correct water fill volume is 80 to 100 cc. To measure the fill volume, test-cycle the Ice Maker and collect the water. Measure in a container calibrated in cubic centimeters (CC) the fill time is 5.0 seconds.

The fill volume is adjusted by increasing or decreasing the length of time the water fill switch remains closed.

To adjust the water fill switch, first determine how much water is needed. The adjusting screw is calibrated so that one complete revolution changes the water fill about 18 cubic centimeters. Turning the screw clockwise decreases the fill, while turning counterclockwise increases the fill.


87

EXAMPLE: An ice maker is test-cycled and the water fill sample is 93 cubic centimeters.

Subtracting 80 cc from 93, the adjustment needed is 13 cc. Since one turn of the adjusting screw changes the fill 18 cc, ¾ of a turn clockwise would reduce the fill about 13 cc, the desired amount.

(This example is for manual models only.)

The Ice Dispenser Container slides into the

Rail Assembly mounted directly below the Ice

Maker. Ice is ejected from the container by an Ice

Auger connected to the Solenoid Assembly, and dispensed at the bottom front of the container where it enters through a Gate on the Crusher

Housing. The Gate is opened and closed by a

Control Rod that fits in the Actuator of the Solenoid

Assembly. The ice is then directed into an ice chute mounted on the interior of the freezer door.

The Ice Container must be properly placed on the rail assembly to assure proper dispensing. The container should be slid on top of the rails on the

Rail Assembly up against the Motor Cover, with the

Rotation Stop and Ice Auger protruding through the holes in the back of the Ice Container.

105

Then remove the screws two screws at the top of the control. Now you can lift up on the control assembly while you tip it out at the top. This will allow you to remove the control assembly from the door.

DISPENSER OPERATION

The dispenser has a user interface section in the control in the door. The auger motor, water valve and cube ice are all controlled on the lower control board. There are two connections on the back of the control one is a 115 V AC connection to supply power to operate the door opening solenoid. The other is a 12 VDC connection from the lower control board to operated the relay that controls the door solenoid. (See Figure 7)

115 VAC Black & Blue

12 VDC Brown & Blue

Figure 7

Control Board for Relay

When the actuator is pressed a low voltage signal

(12VDC) is sent to the user interface on the upper control by way of the actuator switch located on the housing just behind the door solenoid relay.

( See Figure 8 ) The upper board will send a communication to the lower board based on the customers selection of Water, cube ice or crushed ice. If water is selected the communication will open a tri-ack on the lower board for the water valve. If ice is selected it will do the same thing for the auger motor and /or cube ice solenoid.

Remove screws

The lower control board will also send a 12 VDC signal to the relay board and the coil of the relay which will pull the contact set closed. This will send the 115 V AC to the solenoid for 30 mill -a-seconds to open the ice door.

This will open the contact on the ice door switch and allow the ice door linkage to lock holding the door open door open after the 30 millaseconds has passed and the relay opens opening the 115 VAC signal to the door solenoid. (See Figure 9)

Door Switch

Switch Actuator

When the glass is pulled away from the actuator the Actuator switch will open the signal to the lower control board. The lower control board will send a 12 VDC signal to the relay board for 10 milla-seconds to unlock the door linkage allowing the ice door spring to close the ice door. (See Figure

11) This will close the contacts on the ice door switch telling the lower control board the door is closed. If the switch contacts do not close the lower control board will send a 12 VDC signal to the relay board for 10 mill-a-seconds again to unlock the door linkage allowing the ice door spring to close the ice door. The lower control board will continue to do this until the ice door is closed.

Section H - Water System

Water Systems

Water for the ice maker and water dispenser is controlled by a dual coil valve and a single coil valve joined together as one. It’s mounted just to the right of the condenser on the cabinet. Plastic tubing connects the water valve/valves to the ice maker fill tube, the water dispenser, and water filter

(on models so equipped).

Water Valve

Counter Depth models have 1 dual coil valve and 1 single coil valve (see figure H1). The green coil on a dual coil valve is for the ice maker and the yellow coil is for the water dispenser. The beige coil on the single coil valve is energized for both water for the ice maker and dispenser. Plastic tubing connects the primary water valve to the filter, water tank, and to the secondary valve. water to flow through, replace the valve. It is not necessary to replace the whole valve assembly if one coil is bad. The two valves can be separated by inserting a screwdriver at point A in Figure H1.

PureSouce Water Filters

For models with a Front Filter (see Figure H2) . The water filter must be changed at a minimum of twice a year. But, under certain water conditions, such as large concentrations of calcium, alkali, or other particulate matter in the water, a filter may require changing more frequently. A good way to judge whether the filter needs to be replaced is when the water flow to the dispenser starts slowing down and there has been no change to the water pressure to the product. Operating water pressure should be a minumum of 20-100 psi.

Figure H1

A

On models with a single coil valve for a primary, you have 2 diodes in the wiring harness connecting the coil of the single coil valve to the 2 coils of the dual coil valve. The diodes are used to prevent current leakage from opening both coils on the dual coil valve every time the single coil valve is energized.

If a diode is shorted, when the single coil valve opens, current leakage through the shorted diode will cause both coils on the secondary valve to open and you’ll have water going into the ice maker and coming out the door at the same time. If the the diode fails in the open position, the coil on your secondary valve will open, but the coil on the primary valve will not. As a result, you will not get water to the ice maker or dispenser. Both doides can be checked with an ohmmeter to see if they are opened or shorted.

The coils on all water valves can be checked with an ohmmeter to see if the coils are opened or shorted. If the coil checks bad, replace the coil.

If the coils check good and water pressure is between 20-120 psi, and the valve will not allow

Figure H2

NOTE

The condition of the water filter also has a large affect on the operation of the ice maker. When the filter slows down flow to the door, it is also slowing down flow the ice maker. This can reduce the number of ice cubes made per cycle as well as producing small cubes that can jam the ice maker by getting caught between the ejector and the stripper.


121

Water Tanks

Counter Depth refrigerators will have a roll tube tank assembly as shown in Figure H4.

The water line from the primary water valve (single coil valve) goes behind the trim, located on the right side of the inside food compartment liner, to the water filter. From the water filter, the line goes to the water tank, then to the secondary water valve (two coil valve). The two coil valve dispenses water to the ice maker and to the dispenser in the door. By filling the ice maker for the water tank, you will get chilled water to the ice maker helping to increase ice production.

See Figure H5 for water system flow diagrams.

To Test The Water Fill System

The wiring harness has two diodes in the line between the fill switch on the ice maker and the green coil of the secondary water valve, as well as between the water switch or relay on the freezer door and the secondary valve. The diodes are part of the wiring harness. (See wiring diagram, Figure

G10).

If the diodes fail open, the primary valve will not open for ice and/or water depending on what diode is open. The open diode will not affect the coil on the secondary valve. The secondary valve will open but if the primary valve does not open, you will not supply water to the secondary valve.

Resistance Check

To test the diodes you can use an ohm meter with at least a 10K ohm or higher scale. Take a reading across the diode, then reverse your leads and take another reading. The diode should check 10 times higher in one direction than the other.

Voltage Check

You can also use a volt meter to check the circuit.

Connect a volt meter to the valve coil of the primary valve, and connect a second volt meter to the green coil of the secondary valve. If the problem is with the ice maker, or the yellow coil of the secondary valve if the problem is with the water dispenser.

Digital Meter

If you are using a good meter you will read between

0-10 volts with a open diode on the primary valve, and over 90 volts at the secondary.

Voltage Drop From Heater

In checking the voltage on a ice maker fill, you must keep in mind that the coils of the water valves are in series with the heater on the ice maker.

The resistance of the heater will cause a drop in voltage. Example: If you have 110-120 volts at the outlet with the product running, then 92-101 volts will be present at the green coil of the secondary valve.

Valve Coil

The production valves use a 20 watt coil to open the valve. This should open the valve down to about 90 volts at the green coil of the secondary valve. If the voltage is lower than 90 but above 80, you can install a 50 watt service coil (Part Number

5304401081). Keep in mind, you must replace the coil on the primary and the green coil on the secondary valve to resolve the problem.

Voltage Readings are Different Between

Primary and Secondary Valve Coils

If you are getting 10 volts or less at the primary valve, but you are getting 85-100 at the secondary, you have a bad diode. If you are getting 48-58 volts at the primary valve and 90 or higher at the secondary, this is normal. With the current flowing to the primary valve coil through the diode, you are getting 30 cycle instead of 60 cycle current at the coil of the primary valve. Because of this, your meter will only read about 1/2 the voltage that is going to the coil.

No Water at Door

If the ice maker is operating but you cannot get water out the door, the test and operation of the diode is the same as for the ice maker, except for the voltage readings. On the water side, you should read the same voltage at the coil of the secondary valve as you have at the outlet. On the primary valve, the voltage should read 60-70 vac.

If the voltage is low at the primary but good at the secondary, you have a bad diode. If the voltage is low at both the primary and secondary, you have a bad connection or a bad switch in the door dispenser.

Diode Kit

If you have a problem with the diodes,order the diode kit (part number 5303918287. See Figure

H8.) The diodes are part of the wiring harness for the machine compartment.

Checking Water

If you do your voltage checks and find you have the correct voltage at the coils and the valve is not letting water through, replace the valve. To see which valve is bad, disconnect the water line from the filter to the inlet of the secondary valve. Place the line in a bucket.

Ice Maker Valve

Run the ice maker through a fill cycle and see if water will pass through the valve (Green Coil) and the filter into a bucket. If it does, replace the secondary valve. If it does not, remove the primary valve, disconnect the outlet line from the primary valve and run the ice maker through a fill cycle. If there is still no water, replace the primary valve. If water is coming through, replace the water filter.


123

Chilled Water Valve

There are a number of connections in the wiring of a refrigerator. On the ice maker, the wiring runs see if water will pass through the valve

(Yellow

Coil) and the filter into a bucket. If it does, replace the secondary valve. If it does not, remove the primary valve, disconnect the outlet line from the primary valve, then place a glass against the actuator and push. If there is still no water, replace through the plug by the condenser fan motor up to the ice maker, back down to the same plug and into the diode harness. On the water dispenser, motor to the plug at the bottom of the freezer door, up to the dispenser, and back down through the same plugs to the diode harness. A bad connection replace the water filter.
