Door Closure Mechanism

The door closure mechanism uses a spring to provide positive door closure from approximately

60 degrees. The door closure mechanism actuator arm has a spring attached to the rear and is supported by guide rollers on either side of the base channel. The roller circumferences and the actuator arm detents are matched for smooth operation. The arm is attached to the door with an

Allen head shoulder bolt.

The closure mechanism allows easy opening to approximately 90 degrees, where the arm has a detent to permit the door to remain open at 90 degrees with minimal tension. Once the door is opened beyond 90 degrees, the closure mechanism pulls the door open until the closure arm engages the door stop at approximately 130 degrees (factory setting, the door stop can be field set to 90 degrees). The reverse action occurs when the door is closed.

Note: The actuator arm is spring loaded with moderate spring tension.

1. Disconnect the spring from the pin and the actuator arm.

2. Remove the 3/16-in. Allen head bolt, bushing, and spacer from the door and actuator arm.

Water Valve and Water Tank

The water valve is mounted in the left side of the machine compartment.

A plastic water line is routed from under the unit, up the back of the cabinet, into the machine compartment, and to the water filter. A line then goes from the water filter to the water valve.

Two low-pressure plastic water lines supply water to the icemaker and door dispenser from the water valve. A plastic water line is routed from the water valve, out the back of the machine compartment, down the back of the cabinet through the bottom of the unit, and into the fresh food compartment where it is attached to the cold water tank. A line is routed from the cold water tank through the bottom of the unit into the freezer door to supply the water dispenser. The icemaker water line is routed from the water valve through the machine compartment to the icemaker. The icemaker fill tube is also plastic.

Evaporator Fan

The position of the fan blade in relation to the shroud is critical. Refer to evaporator fan adjustment graphic for specifications.

If the fan shorts, it may damage the main control board. If the resistor on the main control board is burnt, you must replace the fan and the board (see photo).

The evaporator fan utilizes a permanent magnet,

4-pole, DC motor that can operate at three different speeds: high, medium, and low (medium and low are the same speed, controlled by the main control board). The speed of the fan is controlled by the voltage output from the main control board. Voltage output from the control board to the fan is 12.6 VDC; however, in order to regulate the speed of the fan, the control board uses Pulse Width Modulation (PWM) during low-

speed and medium-speed operation. When operating in low and medium speeds, voltage is sent in pulses (much like a duty cycle) as opposed to an uninterrupted flow. This pulsing of 12.6 VDC produces effective voltage being received at the motor, which is the equivalent to a reduction in voltage. Fan speed will be selected and maintained by the control board regulating the length and frequency of the 12.6 VDC pulse.

One complete revolution of the motor is comprised of all 4 poles. To determine the rpm of the fan:

Measure the frequency being applied to the motor. Multiply this number by 15 (60 seconds divided by 4 poles). For example, a frequency measurement of 200 Hz multiplied by 15 would show a fan speed of

3000 rpm (15 x 200 = 3000). Temperature may cause some fan speed variation. Fan speed may vary

+/- 5%, depending on the temperature, with higher temperatures causing slightly higher speeds.

The evaporator fan motor uses a 4-wire connection, utilizing a common wire (white), feedback/rpm wire (blue), supply wire (red), and a signal wire (yellow).

White Wire (DC Common)

The white wire is the DC common wire used for testing. During repairs, DC polarity must be observed. Reversing the DC polarity will cause a shorted motor and/or board.

Red Wire (Supply)

Each motor uses an internal electronic controller to operate the motor. Supply voltage from the main control board remains at a constant

12 VDC.

Blue Wire (Feedback/RPM)

The blue wire feeds rpm (speed) information to the main control board, allowing the board to maintain consistent fan speeds. Loss of feedback from the blue wire will result in the fan accelerating to maximum speed. Measure the fan rpm using the frequency between the blue and white wires.

High speed - 195 to 200 Hz

Medium speed - 145 to 160 Hz

Note: Fan operates at the same speed in low and medium.

Low speed - 145 to 160 Hz (same as medium)

Yellow Wire (Signal)

The yellow wire is the input wire from the main control board. The main control board provides

8.1 VDC effective voltage for low speed, 8.1 VDC effective voltage for medium speed, and 12.6 VDC for high speed. The fan will operate in low speed only when the fresh food thermistor is satisfied.

Note: When testing these motors:

• You cannot test with an ohmmeter.

• DC common is not AC common.

• Verify 2 voltage potentials:

a. Red to white - power for internal controller.

b. Yellow to white - power for fan.

• Observe circuit polarity.

• Motors can be run for short periods using a

9-volt battery. Connect the white wire to the

negative (-) battery terminal only. Connect the

red and yellow wires to the positive (+) battery

terminal.

Evaporator Fan

Condenser Fan

The condenser fan utilizes a DC motor that operates at a single speed and is mounted in the machine compartment. When the fan is operating, air is pulled through the condenser, drawing air through the coils. The air is then exhausted past the compressor and out the front of the refrigerator on the right side.

Inlet air is available through the left front and left rear of the machine compartment.

If the fan shorts, it will damage the main control board. If the resistor on the main control board is burnt, you must replace the fan and the board (see photo page 15).

The condenser fan is mounted with screws to a fan shroud and mounting bracket in back of the condenser.

To Remove the Fan

1. Extend the chassis (see Machine

Compartment in the Cabinet chapter).

2. Pull the blade off the motor shaft.

3. Cut the wire tie securing the fan wiring to the fan bracket.

Caution: Fan connector can be separated into 3 segments (center, left side, and right side).

Disconnect the fan connector at the center only.

4. Disconnect the fan connector.

5. Feed wiring through the hole in the fan shroud.

6. Remove 2 screws, top section of fan bracket, and motor.

Defrost System

Adaptive Defrost

Adaptive Defrost can be described as a defrost system that adapts to a refrigerator’s surrounding environment and household usage.

Unlike conventional defrost systems that use electromechanical timers with a fixed defrost cycle time, Adaptive Defrost utilizes an intelligent, electronic control to determine when the defrost cycle is necessary. In order to accomplish the correct defrost cycle time, the main control board monitors the following refrigerator operations:

• Length of time the refrigerator doors were open since the last defrost cycle

• Length of time the compressor has run since the last defrost cycle

• Amount of time the defrost heaters were on in the last defrost cycle

Adaptive Defrost is divided into 4 separate cycles.

Those operations are:

• Cooling Operation

• Pre-Chill Operation

• Defrost Heater Operation

• Dwell Period

(See Pub. #31-9062 for more information on

Adaptive Defrost.)

Adaptive Defrost (Cooling Operation)

During the cooling operation, the main control board monitors door opening (fresh food door and freezer drawer) and compressor run times. The board counts the time the doors are open. It reduces the length of time between defrosts by

300 seconds (multiplication factor) for each second that each door is open (if both doors are open, it reduces it by twice the amount). The multiplication factor reduces compressor run time.

If the doors are not opened, the compressor will run up to 60 hours between defrosts. If the doors are opened frequently and/or for long periods of time, the compressor run time between defrosts will be reduced to as little as 8 hours.

Adaptive Defrost (Pre-Chill Operation)

When the main control board determines that defrost is necessary, it will force the refrigerator into a continuous cool mode (pre-chill). During prechill, the freezer temperature may be driven below the set point. However, the fresh food temperature will be regulated by the evaporator fan running at low speed. Pre-chill will last for 30 minutes. These models do have an 8-hour defrost holdoff.

Adaptive Defrost (Defrost Heater Operation)

After 30 minutes of pre-chill operation, the main control board turns off the compressor, condenser fan, and evaporator fan.

During defrost operation, the main control board monitors the evaporator temperature using evaporator thermistor inputs. Typically, the evaporator thermistor will sense a temperature of

38 °F within 16 minutes. When the thermistor senses 38 °F, the main control board will terminate defrost heater operation. Maximum defrost cycle

(heater on) time is 35 minutes (main control board time out).

The defrost system is protected by a defrost overtemperature thermodisc (bimetal switch). The thermostat opens when the evaporator temperature raises to 60 °F and closes when the evaporator temperature lowers to 45 °F.

Adaptive Defrost (Dwell Period)

After defrost heater operation has been terminated by the main control board, a 20-minute dwell period occurs. During this period, the compressor, condenser fan, and evaporator fan remain off. The remaining frost melting from the evaporator will continue to drip and drain so that, prior to the cooling operation, the evaporator will be totally clear of any moisture. The pan heater is on for the entire 20 minute dwell period.

Normal Operating Characteristics

• Evaporator fan running, without compressor or condenser fan.

• Liner Protection Mode, fan comes on when the doors are open for 3 minutes.

• Different sound levels can be heard when the fan changes speed; however, the fan should never be heard oscillating between speeds.

• Response time for drastic temperature change is 2 to 10 minutes. The main control board will only respond to 8 °F of temperature change per minute as determined by resistance of sensor.

Abnormal Operating Characteristics

(Incorrect Operation)

• Rapid fan speed changes, fan takes at least

1 minute to change speeds.

• Compressor running without the condenser fan. The compressor and condenser fan should always run at the same time.

Liner Protection Mode

The liner protection mode will activate if either of the doors has been open for 3 minutes. This mode will start the evaporator fan on high speed.

This mode is controlled by 2 timers. Timer #1 monitors door-open time. A 3-minute door-open count begins when the door is opened. If

3 minutes elapse before the door is closed, the liner protection mode will become active. Once the door is closed, timer #1 resets and liner protection mode goes into standby. In standby, normal fan and damper operations resume and timer #2 begins a 3-minute door-closed count.

If 3 minutes elapse without a door opening, liner protection mode will completely deactivate. If a door is opened within the timer #2 door-closed count, the remaining time in the door-closed count will be deducted from the timer #1 door-open count.

Defrost Heater

Caution: Use care to avoid scratching the finish on unit walls.

The defrost heater is a single calrod-type, radiant heater mounted on the evaporator.

To remove the defrost heater:

1. Remove the evaporator fan (see Evaporator

Fan procedure in the Airflow chapter).

2. Remove 8 screws and freezer ceiling panel.

3. Remove Styrofoam insulation from the bottom of the evaporator drain pan.

Evaporator Thermistor

The evaporator thermistor is mounted on the upper left side of the evaporator. The defrost cycle will terminate when the main control board detects 38 °F from the evaporator thermistor. The main control board must sense 38 °F in less than

35 minutes, or the defrost cycle will time out.

Average time to defrost is less than 16 minutes.

Defrost time should not exceed 35 minutes.

Defrost time does not include dwell period.

Defrost Overtemperature Thermodisc

The defrost overtemperature thermodisc (bimetal switch) is mounted on the evaporator and provides overtemperature protection during defrost. This thermostat will open at 60 °F and will close at 45 °F.

Note: The main control board will not know if the heater does not come on due to a broken heater, open defrost overtemperature thermodisc, or open wiring harness. The defrost heater is controlled by maximum time on the main control board or temperature at the evaporator thermistor.

Control System

Touch Panel and

Temperature Control Board

The temperature control assembly is located at the top front of the fresh food compartment and contains the touch panel and temperature control board.

The temperature control board receives switched

DC voltage from the main control board. Input consists of pins 2 to 3. Failure of input results in default to most recent setting. Pin 1 provides digital communication between the temperature control board and the main control board. Failure of communication results in erratic control.

To remove the temperature control assembly:

1. Remove the light cover.

2. Remove 4 Phillips screws and the light assembly.

Note: Temperature control assembly is mounted on 3 slotted fasteners. Fasteners do not need to be loosened or removed.

3. Cut the RTV around the edge of the temperature control assembly.

Note: Old RTV must be removed from the inside of the fresh food compartment and from the temperature control assembly. RTV 102 must be put in place when the temperature control panel is installed.

4. Disconnect the temperature control assembly wiring connector.

5. Slide the temperature control assembly back to release it from the slotted fasteners and lower the assembly.

6. Disconnect the wiring connector from the temperature control board.

7. Slide the touch panel out of the temperature control assembly.

8. Remove 2 screws and the temperature control board.

Climate Control Drawer

The Climate Control Drawer can chill or thaw items quickly. It can also store items at their optimum temperatures. This Climate Control Drawer contains the following components:

• Control Board

• Thermistor

• Dampers (2)

• Fan

• Heater

The main control board controls the dampers, fan, and heater based on input from the Climate Control

Drawer’s control board and the thermistor.

The Climate Control Drawer compartment is sealed to reduce the effect that the drawer temperature has on the rest of the refrigerator. When the drawer features are not being used, the temperature inside the drawer will be the same as the fresh food compartment.

Operation

During all modes of operation, the main control board will cycle the dampers, fan, and heater as necessary to maintain the desired temperature. Typical operation is as follows:

Select Temp

This feature maintains optimum temperatures for specific items.

The CITRUS setting will maintain a drawer temperature of 43 °F by circulating warmed air or cooled air as needed. The dampers will close and the heater will turn on if warmed air is required to maintain

43 °F. The dampers will open if cooled air is required.

The PRODUCE setting will maintain a drawer temperature of 34 °F by circulating warmed air or cooled air as needed. The dampers will close and the heater will turn on if warmed air is required to maintain

34 °F. The dampers will open if cooled air is required.

The MEAT setting will maintain a drawer temperature of 32 °F by circulating warmed air or cooled air as needed. The dampers will close and the heater will turn on if warmed air is required to maintain

32 °F. The dampers will open if cooled air is required.

The Climate Control drawer display will show the selected temperature for approximately 4 seconds after a Select Temp mode has been selected. After approximately 4 seconds, the actual temperature of the drawer will be displayed. Refer to the Temperature Table for drawer temperatures.

Express Chill

This feature cools items by opening the dampers and circulating air from the freezer compartment throughout the drawer. The fan will be on at all times during Express Chill.

The Climate Control Drawer display will show the number of minutes (or minutes remaining) for the

Express Chill mode selected on the control panel. The display will not show the temperature of the drawer. Refer to the Temperature Table for drawer temperatures.

Express Thaw

This feature thaws items by circulating warmed air throughout the drawer. Temperature is maintained in the drawer by cycling a small heater on and off as needed. The dampers will be closed during Express

Thaw. The fan will be on at all times during Express Thaw.

When the Express Thaw cycle is complete, the drawer will automatically adjust to 30 °F.

The Climate Control Drawer display will show the number of hours (or hours remaining) for the Express

Thaw mode selected on the control panel (.5 LBS = 4 HRS, 1.5 LBS = 8 HRS, 3 LBS = 12 HRS). The display will not show the temperature of the drawer. Refer to the Temperature Table for drawer temperatures.

– 34 –

Temperature Table

When using the Temperature Table, please note the following:

• FF and FZ compartments should be within 3 °F of the temperature set point when checking drawer temperature.

• All temperatures listed are as measured by the thermistor and displayed by the Climate Control

Drawer display.

• Actual drawer temperature will be displayed in Select Temp mode only. The Climate Control Drawer display will show the selected temperature for approximately 4 seconds after a Select Temp mode has been selected. After approximately 4 seconds, the actual temperature of the drawer will be displayed.

• The actual-temperature display is based on the temperature that the main control board sees from the thermistor. The selected-temperature (example: CITRUS – 43 °F) is based on the logic of the

Climate Control Drawer control board. If the actual temperature that is displayed is incorrect, the thermistor and main control board are suspect. If the temperature associated with the Select Temp mode is incorrect, the Climate Control Drawer control board is faulty.

Note 1 Climate Control Drawer may take up to 1 hour and 45 minutes to achieve temperature with no load in drawer (except metal tray) and minimal or no door openings.

When the Express Thaw cycle is complete, the drawer will automatically adjust to 30 °F.

Note 2 Temperature should lower to 25 °F or less within 15 minutes with no load in drawer (except metal tray) and minimal or no door openings. Temperature should lower to a temperature between 15 °F to 20 °F within 30 minutes with no load in drawer

(except metal tray) and minimal or no door openings. If refrigerator is defrosting, temperature in drawer may go below 15 °F.

Note 3 Climate Control Drawer may take up to 1 hour and 45 minutes to achieve temperature with no load in drawer (except metal tray) and minimal or no door openings.

Control Board and Display

The control board and display are located in the

Climate Control Drawer top panel (mullion). The control board and display are part of the mullion and cannot be replaced separately.

Input from the Climate Control Drawer’s control board and the thermistor is used by the main control board to control the dampers, fan, and heater.

Actual drawer temperature will be displayed in

Select Temp mode only. The Climate Control

Drawer display will show the selected temperature for approximately 4 seconds after a Select Temp mode has been selected. After approximately 4 seconds, the actual temperature of the drawer will be displayed.

The actual-temperature display is based on the temperature that the main control board sees from the thermistor. The selected temperature (example: CITRUS – 43 °F) is based on the logic of the Climate

Control Drawer control board. If the actual temperature that is displayed is incorrect, the thermistor and main control board are suspect. If the temperature associated with the Select Temp mode is incorrect, the Climate Control Drawer control board is faulty.

Caution: When assembling the top panel, use care to prevent pinched wires.

Troubleshooting

Use this diagnostic flowchart if the Climate Control Drawer control panel and display are not operating properly.

If the problem is drawer temperature and the control panel and display appear to be operating normally, check the thermistor, damper, fan, and heater first.

If the actual drawer temperature displayed is incorrect, suspect the thermistor and main control board.

8. Remove 5 screws and fan housing from fresh food compartment.

Note: When installing the diffuser onto the fan housing, the tabs must be on the bottom and the flat surface must be on top. Incorrect installation will prevent the drawer from cooling and warming properly.

Dampers

Caution: Do not manually move damper door. Manually moving damper door will damage damper.

The dampers are located between the fan housing and the center mullion. The fan housing must be removed from the fresh food compartment to replace the dampers.

Both dampers always operate at the same time. The upper damper can be viewed from the Climate

Control Drawer compartment. The lower damper can be viewed from the freezer compartment. Dampers will be closed during Express Thaw and will be open during Express Chill.

The main control board opens and closes the damper based on input from the Climate Control Drawer control board and the thermistor.

After selecting Express Thaw, 12 VDC are output from the main control board for approximately 4 seconds to close the damper. This voltage can be measured at the following points:

• Main control board J5-2 to J5-1 with positive (red) test meter lead on J5-2.

• 9-pin connector behind Climate Control Drawer.

Check from gray wire to yellow wire with positive

(red) test meter lead on gray wire.

After selecting Express Chill, 12 VDC are output from the main control board for approximately 4 seconds to open the damper. This voltage can be measured at the following points:

• Main control board J5-1 to J5-2 with positive (red) test meter lead on J5-1.

Door Switches

The fresh food and freezer door switches are located at the top of the fresh food and freezer compartments.

The fresh food door switch closes when the door is open, providing L1 to the fresh food compartment light transformer.

The freezer door switch is a dual-pole switch. It provides L1 to the main control board when the freezer door is closed. When the freezer door is open, the switch provides L1 to the freezer compartment light transformer.

Master Light Switch (Sabbath Switch)

The master light switch is located behind the grille panel, on the main control board cover. The switch will open the circuits between the door switches and the transformers, disabling both transformers and stopping voltage output to the interior lights.

Temperature Overload Device (TOD)

A temperature overload device is wired in series with both the fresh food and freezer compartment transformers. If the interior lights should reach excessive temperatures due to a door being open for an extended period, the corresponding TOD will open the circuit that supplies 120 VAC to the transformer.

The TOD will open at 150 °F and close at 90 °F.

The freezer TOD is located behind a metal cover on the back wall of the freezer compartment, at the base of the light tower. The fresh food TOD is located on the back wall of the fresh food compartment, at the base of the light tower.

Circuit Breakers

Two resettable circuit breakers are located on the front of the transformer tray. Should a circuit breaker trip (open), it will open the transformer circuit it is associated with (freezer compartment or fresh food compartment), disabling that transformer and stopping voltage output to the interior lights.

Transformers

Power is supplied to all interior lighting by 2 transformers. One transformer is used for each compartment. The transformers supply lowvoltage power to the lights by converting 120 VAC into 12 VAC.

The transformers are located in a tray under the center of the refrigerator. The tray is accessible from the front of the refrigerator. To access the transformers, lift up on the front of the tray and pull out.

Refrigeration System

The major components of the refrigeration system are a reciprocating-type compressor, condenser, condenser loop, dryer, and evaporator. These components, except for the condenser loop, are all replaceable separately.

Compressor

The compressor is a reciprocating type. Refer to the mini-manual for the BTU/hour rating and the compressor capacity test specification.

A copper process tube is provided for access to the low-pressure side of the refrigeration system.

Note: The woodpecker clip holds the capillary tube in thermal contact with the compressor discharge tube. If the capillary tube is not clipped to the discharge tube, a knocking noise may occur during compressor operation.

Evaporator

Refer to the compressor replacement instructions included with the replacement compressor.

Condenser

The condenser is located behind the grille panel at the top of the refrigerator and is made of copper tubing. The outlet of the condenser is connected to a copper jumper tube that is connected to the inlet of the condenser loop. In a normal home environment, there is no need for routine condenser cleaning. However, in environments that may be particularly dusty or greasy, the condenser should be cleaned periodically for efficient refrigeration operation. An ordinary appliance brush should be all that is needed.

Functionally, the condenser does the same job as previous models. Air is drawn through the condenser by the condenser fan from the front left and rear left of the machine compartment. Air exits only from the right side of the machine compartment.

Condenser Loop

The condenser loop, made of copper tubing, is foamed in place behind the breaker frame on the freezer compartment side. It is not accessible for replacement. The tubing is routed from the machine compartment, forwarded to the mullion, down to the freezer compartment, around the front perimeter of the freezer, and back into the machine compartment. The outlet of the condenser loop is connected to the dryer inlet.
