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

Important Service Information:
Submission of Warranty Claims Time Frame
Effective March 1st, 2004, all warranty claims must be submitted no later than 60 days after completion of service.
Claims not submitted within this time frame will be rejected. If you have any questions please contact the Service
Assistance Center at 866-646-6810.
Elux Express Shipment Program
Each Parts Distributor location (branch) can order up to ten different part numbers (line items) per day through the
ELUX EXPRESS part shipment program. These parts will be shipped 2nd day Air direct to the Parts Distributor
location. The parts will arrive within 2 business days with no shipping charges to the Parts Distributor. In effect,
Electrolux Home Products has suspended all freight charges on EMERGENCY 2nd day orders. However, if the
Parts Distributor has to ship the part from their location once they receive it, there may be added freight charges
and possibly additional day(s) delay in getting the part. But the Parts Distributor does not have to wait until he has
a stock order to provide you the part to satisfy our mutual customer.
Failed Parts Return Program
EHP needs your help. In order to substantially improve the quality of our finished goods, EHP must analyze
component part failures within the warranty period. This effort requires closer connectivity between our service
community and the supply base. Therefore, we are asking service technicians to help us by returning specific parts
that fail in the field to the appropriate factory for testing. You can easily identify which parts need to be returned to
EHP. The replacement parts will come with a prepaid FedEx shipping label that will allow you to ship the old, failed
part back to EHP. It is very important that these parts are returned with a copy of the service invoice included and/
or the questionnaire sent with the replacement is filled out. Be sure to use the pre-paid FedEx shipping label
provided by EHP because not all parts are returned to the same location. Thank you for your help in this very
important project to improve product quality.

Refrigeration Information:
PROBLEM:
Freezing food in food compartment on Standard Side by side Refrigerators.
CAUSE:
There are a number of problems that can result in freezing of food in the food compartment (or having
warm food compartment temperatures).
SOLUTION:
The freezer temperature should be in the -1 to +3F range (factory mid range setting) and the food
compartment should be +36 to +38 F (factory mid range setting). When checking the refrigerator
use the information below as a guide to insure you cover all the possible causes of food freezing in
the food compartment or the water filter freezing.
Step 1:
Check both the freezer and the food
compartment temperatures . (At the midrange setting the freezer should be between
-1 and +3 F. The food compartment should
be +36 to +38 F.)
If the freezer is -10 F or
colder, set at mid point.
If the freezer is + 8 F or
warmer, set at mid point
Check the wattage
on the compressor.
If the wattage is normal
check the evaporator to
see that the evaporator
is not partly blocked.
If the evaporator is
blocked check the
defrost system.
Also check for air
leaks and check
the door closers.
You have a bad freezer control and the air entering
the food compartment is so cold it is starting to
freeze food on the top shelf by the damper before
the damper has a chance to close. This should
not cause the food to freeze in the rest of the
compartment. May freeze the rear filter on models equipped with rear filters.
If the wattage is low or
high you have a problem
with the sealed system
such as a restriction,
low refrigerant charge or
inefficient compressor.
Use data sheet provided
with product for correct
wattage information.
If the food is freezing throughout the
complete food compartment, you have
an additional problem beside the
freezer control and will need to follow
the instruction for checking the food
compartment control system.
If the evaporator is clear check the evaporator fan motor to see that it is running at
normal speed. If it is running slow you have
a bad fan motor or a bad ADC control.
If the evaporator fan motor checks
OK you have a bad freezer cold
control.
NOTE: Keep in mind the food compartment cold control closes the damper door at +15 F and reopens the door at
+35 F at the mid range setting. The temperature of the air coming through the damper must be +15 F at the mid
range to close the damper. If the air temperature is +18 F the damper will not close and the food in the food
compartment will freeze.
8
Step 2:
If the freezer temperature is good but food compartment is too
cold, you will need to check the food compartment cold control and
the damper control assembly.
Using an inspection mirror, look in
the air outlet grill at the back of the
control housing in the food compartment. See if the damper door is open
or closed. It should be wide open or
completely closed.
If the damper door is all the way open
or closed and you do not find any
obstructions holding the door, follow
instructions in Step 3.
If you find the door
part way closed.
If the door is straight up and
down but part way closed,
check for obstructions.
If the cap tube from the
freezer control is catching
on the door and not allowing
it to close, remove control
housing and reposition
freezer control cap tube in
proper location.
The damper control is
broken, or the door is
catching the foam block,
replace the control.
If you find the
damper door at an
angle, the door
hinge pin is out of
place. Replace the
damper.
If you find ice holding the
damper door open, check for air
leaks allowing excess moisture
to enter the product.
Check to see that
the door closers are
closing the doors
Caution the customer to make
sure the food packages are
not keeping the doors from
closing all the way.
Check the door seals
for good contact, the cabinet
and the door alignment with
the cabinet. Make all necessary adjustments.
Check to see that the door seal is tight in the channel of the
inner door panel. If the seal can be pulled out of the channel
easily, remove the seal and run a bead of silicone sealer in
the channel and reinstall the gasket. Also check the
opening in the bottom of the food compartment that the
water lines enter for proper sealing of the opening.
NOTE: If there is ice in the damper door holding the damper door open, ther e is an excess amount of moisture entering
the product and it is not all condensing on the evaporator coil. When the circulating air still contains a large amount
of moisture as it turns to go through the damper, it will slow down and this will allow the moisture to condense on
the damper door. The moisture will then run down and freeze on the bottom of the housing. If the cause of the ice
forming on the bottom of the damper housing is a result of heavy use in a humid environment, there is a heater available
to install on the bottom of the damper housing. The heater is part number 5303918267.
9
Step 3:
If the damper has no ice or obstructions
keeping it from operating, you will need to test
the food compartment control, damper motor
and ADC on models with ADC II.
On refrigerators built after serial number LA123 or models that
have had a updated control box installed you can operate the
damper from the food compartment cold control.
On refrigerators built before
serial number LA123 drop the
front of the control panel
housing by removing the front
and one side screw. This will
allow the control panel to drop
down and hang on the one
rear screw and wiring harness.
Turn the food compartment cold control all the way counterclockwise until it stops. This should turn on the damper
motor and close the damper door. Turn the control back up
to a cold setting and the door should open.
If damper motor will open
and close the damper,
replace the food compartment cold control.
If damper motor will not run,
drop the control box and check
the food compartment control to
see that the contacts are
opening and closing.
If the contacts are operating, replace the
damper.
NOTE: To check the control contacts use the
information on page 14. Page 14 will also point
out if the product has a ADC I or ADC II. (If
product has a ADC II see Note below.)
If the damper door is open, you can
jump between the number 2 contact
(Black Wire) on the food compartment
control and the number 3 contact
(Pink Wire) and this should close the
damper door. See page 14 for control
information.
If damper motor will open
and close the damper,
replace the food compartment cold control.
If the contacts are not
operating, replace the
food compartment cold
control.
If the damper door is closed, you can jump
between the number 2 contact (Black Wire) on
the food compartment control and the number
1 contact (Purple Wire) and this should open
the damper door.
See page 14 for control information.
If damper motor will
not run, replace the
damper assembly.
If damper motor will open
and close the damper,
replace the food compartment cold control.
If damper motor will
not run, replace the
damper assembly.
NOTE: If you are testing a product with a ADC II follow the instructions on page 14 through 18 to test the food
compartment control damper and ADC.
10
Items to look for when replacing the control box assembly:
When the control box assembly is
removed make sure that the white
plastic capillary tube cover is removed
along with the capillary tube.
The capillary tube should lay in the foam
block groove as shown. The white plastic
capillary tube cover should be within 1/4” of
the foam block as shown.
Make sure that the capillary tube is not
kinked and that it goes through the
small hole in the damper opening of
the fresh food liner.
11
Items to look for when replacing the control box assembly (cont):
When the control box is
installed properly the housing
will be touching the food
compartment liner
When the control box assembly
is reinstalled make sure the screw
in the back of the control box is all
the way in and tight
Make sure the cam switches are
connected correctly and the wiring harness
is not placed under the switches in a position
that will allow them to get into the cam
12
Damper Heater Kit P/N 5303918267 for the 2001 Side by Side Refrigerators:
This kit will allow the installation of a 1.0 Watt heater on the bottom of the air damper assembly to control frost or
ice from collecting on the bottom of the housing stopping the door from closing when the control is satisfied.
1. Remove the control housing from the food compartment.
2. Remove the damper assembly from the control housing and separate the two foam blocks covering the housing.
CAUTION: Use caution when separating the block so not to break the foam.
3. Remove the film from heater ( See Figure 1 ) and attach to inlet side of housing on bottom. ( See Figure 2 )
FIGURE 2
FIGURE 1
4. Slide inlet side of foam block over housing and heater. ( See Figure 3 ) Now slide outlet side of foam block over
the housing. ( See Figure 4 )
FIGURE 4
FIGURE 3
5. Re-Install damper in control housing. Cut the Blue wire going to the damper motor ( See Figure 5 ) and
using the connector and heat shrink in kit splice one side of the heater to the neutral wire. ( Blue Wire )
6. Cut the Red wire going from the defrost control or timer to the compressor ( See Figure 5 ) and using
the connector and heat shrink in kit, splice one side of the heater to the line wire. ( Red Wire )

Cold Control and ADC Changes on Standard 23 and 26 Cu. Ft. Side by Side Refrigerators:
A change in the food compartment cold control on side by side refrigerators from the GE to a Robertshaw took place
in January of 2003. The new Robertshaw control is in use in the control box kit part number 5303918283 and is used
in production of refrigerators built after serial number LA301. The controls can be identified by the marking on the
control and the color of the body of the control. The GE will have the GE Logo on the end of the control and it has
a white body on the contact set part of the control. The Robertshaw will have the name Robertshaw on the end of
the control and it has a gray body on the contact set part of the control. The electrical connection will be different
between the two controls, on the GE control the number 1 contact has a purple wire with a white tracer, number 2
has a black and number 3 has a pink wire connected to it. (See Figure 3) On the new Robertshaw control the number
1 contact is pink, the number 2 is still black and the number 3 is purple with a white tracer. (See Figure 4) As you
can see the pink and purple with the white tracer are reversed between the two controls. The new wiring diagrams
will show both controls. The confusion in the field is servicers installing the 5303918283 kit are connecting the
Robertshaw control up to the information on the product wiring diagram that is for the original GE control. This is also
the case when servicers are installing the food compartment cold control. This will cause the damper to stay closed
when the food compartment is calling for cooling, but the damper door will open when the control is turned to the off
position.

Summary of Changes to the Control Box on Standard 23 and 26 Cu. Ft. Side by Side Refrigerators:
The new damper and ADC went into production the end of July 2003 on 23 foot and second week of August 2003 on
the 26 foot side by side refrigerators. (See Figure 1 below.) The ADC II is smaller and mounts in its own frame in
the same location as the ADC I. (See Figure 2below.) The new damper is mounted in the same location. (See Figure
3 below.) The part number of the new damper is 240521107 and the part number for the ADC II is 241508001. The
food compartment cold control will change from a 3 terminal to a 2 terminal control. NOTE: There will be a few control
boxes that will still have the 3 terminal control but the number 1 contact is not used. (See Figure 4 next page.) The
control box is mounted the same way as in the past but there will be a difference in the way the control system is
tested. The damper motor is now controlled through the ADC II.

The replacement of the cold controls and damper are the same on both control boxes. The ADC II is mounted inside
a box. To replace, use a small screwdriver and release the tabs in the front of the control box. (See Figure 5.) This
will allow you to remove the cover and get to the board. (See Figure 6.) Now lift the ADC out of the housing and
disconnect the plug. (See Figure 7.)

How the ADC II functions:
NOTE: All voltage testing is 115 Volt AC.
The food compartment cold control sends 115 V to the ADC when the control calls for cooling in the food compartment
and the control contacts close. When the cold control sends 115 V in on the number 9 contact, the ADC will send
115 V out the purple white wire on number 3 contact to open the damper door. When the food compartment control
cut out point is reached the contact will open. This will remove the 115 V signal from the number 9 contact. The ADC
will now remove the 115 V from the purple white wire and send the voltage to the pink wire on number 8 contact and
the damper door will close. The freezer control is supplying the 115 V to the common contact of the relay on the ADC
by way of the orange wire on number 4 contact. The compressor is connected to the normally closed contact on the
relay by way of the red wire on number 6 contact of the ADC. The defrost heater is connected to the normally open
contact of the relay by way of the brown wire on the number 2 contact of the ADC. The food compartment light switch
is connected to the ADC by way of yellow black wire on the number 7 contact.
You can start the refrigerator into or bring the refrigerator out of a defrost cycle by pushing the food compartment light
switch 5 times in 6 seconds. The evaporator fan motor operates off the ADC by way of the red white wire on the number
11 contact. The evaporator fan will run when the food or the freezer compartment controls call for cooling. There is
a wire connected to the ADC from the defrost limit switch by way of the blue black wire on number 12 contact. A signal
change when the defrost thermostat opens tells the ADC to turn off the defrost heater and allow a 6 minute delay,
then turn the compressor and condenser fan back on and start the evaporator fan after one additional minute. 115V
to the ADC’s power supply can be tested by placing one lead of a volt meter into the light blue neutral wire on number
10 contact and the other lead to the black wire on the number 1 contact. With the lead from your voltage meter still
in the light blue wire you can check the voltage output of each of the wires as explained above. If you get the correct
voltage readings the ADC is good. Use the pin/plug diagram shown in Figure 8 for test points and correct wire color
code. This diagram can also be found on the cover of the ADC but can be hard to read.

How to tell the difference between damper assembly 240521103 used to build kit 5304428265 as well as the
control box kit 5303918282 and the 5303918283 kits built before October 2003:
The new damper part number 240521107 went into production in June 2003 on 23 and 26 foot side by sides. The
damper kit 5303918283 was converted to the new damper in September production and became available in October.
The changes made to the damper door and the pivot point for the door allow for extra clearance. The round pins are
not prone to freezing in place. The changes in the design made it possible to remove the damper heater part number
5303918276 from the damper used in the 5303918283 kit. However, the heater is still available as a service kit from
service parts.

PROBLEM:
Icemaker bale arm is dropping all the way down after a harvest cycle as a result the shut off switch
is remaining open and the ice maker stops producing ice. A very slight tap on the arm will allow it
to drop the rest of the way down and the icemaker will start to operate.
CAUSE:
The bale arm spring is not strong enough to overcome freezing grease or a wire nut not positioned
correctly or a bind on the face plate of the ice maker. (See Figure 1) Ice is forming inside the housing
or on the on/off switch. The lever arm is sticking and adding additional pressure on the bail arm.
SOLUTION:
In October of 2003 the supplier of the ice maker changed to a low-temperature grease that will not
absorb water to eliminate the grease becoming water soaked and freezing. Additional quality checks
were put in place to insure the wiring is in the correct location and a new tool was made to improve
the alignment of the housing and the face plate. To repair the ice makers in the field you can order
bail arm spring p/n 3206348 which is a stronger spring. When replacing the spring remove all the
lubricant and replace with low temperature food grade lubricant p/n 5304435999. ( See Figure 2 )
Check the arm lever to see that the screw is tight but not so tight to cause the arm to bind. This screw
is a shoulder type and if it is loose check to see that the lever arm is on the shoulder not not pinched
between the shoulder and the housing.(See Figures 3) Before you reinstall the steel plate add a
screw to the open screw hole or fill the hole with sealer. ( See Figure 4 ) When reinstalling the front
face plate after the spring is replaced check to see that wire nut is in the correct location. (See Figure
5). After the steel face plate is installed loosen the screws slightly if you feel a binding on the bail
arm as you lift it up and down by hand. (See Figure 6)

PROBLEM:
Ice cubes falling over the side or back of the ice bucket on side by side refrigerators with the ice maker
mounted across the back of the freezer.
CAUSE:
Deflector missing or out of place on ice maker and on some models from the ice bucket.
SOLUTION:
On side by side refrigerators with the ice maker mounted across the back there is a deflector part
number 241583301 mounted on the stripper of the ice maker. (See Figures 1and 2 ) This deflector
has two reasons for being installed correctly. First it directs additional air at the bottom of the ice
maker to increase production. Second it stops ice from falling over the back of the bucket. It is
important that it is in place and the bucket is all the way back against the stop.

PROBLEM:
Ice and frost forming on the solenoid and auger motor on side by side refrigerators.
CAUSE:
Air leaking into the refrigerator and/or heavy usage is producing a lot of additional moisture inside
the refrigerator.
SOLUTION:
For air leaking into the refrigerator see Service Bulletin January 2004, page 7 for sealing the water
line opening in the bottom of the food compartment. This will help control a lot of moisture infiltration
into the cabinet. It should be checked on all products and sealed if necessary. In addition to sealing
the air leaks, if you can add additional air flow through the housing where the auger and solenoid
are mounted, this will help keep the moisture from condensing and building up on the auger and
solenoid. You can add the additional ventilation by drilling 6-3/8 inch holes in the bottom of the
housing. (See Figure 1) Also drill 15 - 3/8 holes in the back of the plastic cover over the housing.
(See Figure 2) The cover can not be removed and disposed of. It is a UL requirement that this cover
is installed to prevent a person from putting their hands into the wiring when reaching behind the
housing to clean the product.The foam block over the solenoid needs to be sealed tight against the
steel housing top to bottom. This may require that the wires to the solenoid be rerouted to allow the
block to sit correctly. (See Figure 3 ) If you can not get the block to sit correctly in place the block
can be removed when the ventilation holes are opened in the housing. It is better to remove the block
than have a block that will not seal against the steel housing. Replacement rear covers are available
with holes already drilled. For 23 cu. ft. units, order p/n 241577301. For 26 cu. ft. units, order p/n
241577302.

PROBLEM:
Heavy frost build up on evaporator but defrost system is working. Ice is building on cube ice solenoid
and/or auger motor as well as damper.
CAUSE:
Air is leaking into the product
SOLUTION:
In addition to checking for a good seal between the door gasket and the cabinet, also check for a
good fit of the door gasket into the door channel. Another place to look that is missed by a lot of
servicers is the seal on the opening in the cabinet at the point the water lines enter. This opening
is in the bottom right corner of the food compartment behind the light shield. The opening must be
sealed all the way around. It would be a recommended service practice to have a servicer check the
opening on any product you are servicing to make sure it is sealed.
WATER LINE OPENING
MAKE SURE OPENING
IS SEALED COMPLETELY
PROBLEM:
Repeated leaking of front water filter.
CAUSE:
High water pressure.
SOLUTION:
We have found from testing that water pressure in the 90 PSI and higher range have caused repeated
leaking of front water filters. The filter and base can be replaced and adjusted properly, then in 4 to
6 months the filter starts to leak again. There is now an in-line regulator that can be installed in the
inlet side of the water filter. (See Figure 1) The part number for the regulator is 241556001. The
regulator will hold the pressure on the filter and water system at 60 to 65 PSI with up to 150 PSI line
pressure.
To install:
1.
2.
3.
4.
Remove the cover from the water lines going to the front filter.
Remove the inlet water line (Brown line on right hand side)
Push the water pressure regulator into the filter base inlet.
Reinstall the water line and cover.

NOTE: On current production, the “o” rings have changed to a larger size, the ends of the filter are
slightly longer, the back of the filter housing is not heat welded to the main housing, and the screw and
the screw holes are removed from the back of the housing.

PROBLEM:
Front water filter will not eject when button is pressed to release filter
CAUSE:
It was found in test by the vendor and the factory that the spring clip in the base that holds the filter
in place had a burr on one of the four fingers.
SOLUTION:
The release lever would release three of the fingers, but the 4th (upper left hand) would catch on the
filter and not let go unless you push in on the filter and the button at the same time. The spring clip
is symmetrical, so it could be put in with the burr at the top left (worst position from a functional stand
point) or right bottom (best position). There is now a 100% Line check in place to make sure the
filter will release. In the field the spring clip can be removed and turned over and reinstalled or the
filter base replaced to take care of the problem.

PROBLEM:
Top mount refrigerator installed in a garage and the food in the freezer is defrosting when the
temperature in the garage goes below 55 F.
CAUSE:
On top mount refrigerators the compressor and evaporator fan are cycled from the food compartment
temperature. When the ambient room temperature gets colder than 55 F the cold control waits for
the food compartment to warm enough to close its contacts. This long off time allows the freezer
temperature to get high enough that food can start to defrost.
SOLUTION:
There is a kit for refrigerators installed in applications where the temperature can go as low as 34
F and still maintain good freezer temperatures. The kit part number is 5303918301 and contains a
heater that mounts in the control box. An instruction sheet is included to illustrate the heater
installation.
NOTE: This is not a warranty repair. Claims filed with this part number will be rejected.

PROBLEM:
Use of hard start kits.
CAUSE:
We have found a number of hard start kits installed on refrigerators returned from the field. We have
also found reference to hard start kits being installed on products when looking at service reports
in Service Bench.
SOLUTION:
Electrolux will not pay for a hard start kit on a warranty claim. The reason for this is Electrolux Home
Products does not want hard start kits permanently attached to compressors on products we have
manufactured. The original starter package used to start the compressor has a overload set to the
compressor manufacturer’s specification for the maximum amount of current the compressor can
safely pull. The overload is approved by UL for use with that compressor. The overload also is very
close to the body of the compressor and can monitor the temperature of the compressor case. It
will shut off the compressor if the case temperature exceeds a safe level. The product is built this
way to protect both the compressor and the customer's property from damage.
There are problems with hard start kits that do not fall into the original manufacturer’s specifications.
Number one, the overload range on the hard start kit is in most cases well over the acceptable range
set by the compressor manufacturer and UL. Number two, the hard start kit does not monitor the
compressor case temperature of the compressor and therefore can not shut off the compressor if
it is getting too hot. Number three, the hard start kit does get hot and this greatly limits where the
kit can be installed without causing damage to the wiring or waterlines in the product. This is why
Electrolux does not recommend the use of a hard start kit other than a temporary means of operating
the product until the correct parts can be installed. This means you could install a hard start kit
temporarily to keep the product operating in the event you do not have the correct replacement starter
or compressor on hand to properly repair the product.
Before you install a hard start kit on a inoperative compressor you should connect the compressor
on a test cord and check the current draw with a watt meter or amperage tester. If the current draw
is within the specifications on the service data sheet provided with the product, and the system is
operating OK on the test cord, the starter needs to be replaced. If you do not have the correct starter
you could use a hard start kit to keep the product operating until you can return with the correct part.
Use caution when installing the hard start kit to see that it is not close to the wiring or waterlines
in the machine compartment and that it is far enough away from the customer's floor so it will not
cause any discoloration to flooring or carpet. If the current draw is just a little over the rating on the
service data sheet, the hard start kit may keep the compressor operating for a short period of time
until you can install a new compressor. Because the overload on the hard start kit is raised higher
than the original OEM part it may be able to operate the compressor for a short period of time. It
is not a permanent cure, if a compressor is starting to go bad it needs to be replaced. If the starter
is bad it needs to be replaced with the correct part for the compressor in the product.

VCC or Variable Speed Compressors:
The new series of very high efficiency compressors is equipped with all new electrical components consisting of a
power input electronic control.
Power Input Electronic Control (Inverter):
The solid state power input electronic control consists of the following:
Low voltage power supply
EMI Filter and Voltage Suppressor Circuit
AC-DC Converter
Three-phase Inverter Bridge
Serial communication
Microcontroller or DSP Controller Protection
Voltage Sensor
The Inverter replaces the Solid State Relay, the Overload Protector, and the Run Capacitor. The Inverter
has 115 VAC current to it all the time the refrigerator
is connected to the line voltage. It picks up the voltage 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 toe grill.
Inverter
Compressor
To Check/Replace the Inverter:
1. Use a Multimeter or a good Voltmeter set on 300 VAC to test the voltage going into the Inverter from the
service cord. Do not disconnect the Molex connector. Slide your probes from your meter in along side the
wires until you connect with the terminal itself. You should read 115 VAC +/- 10%. If the reading is less
than that, check the power cord and supply voltage.
2. Set your meter to DC on a scale as close to 10 volts as is available. Do not disconnect the Molex
connector. Slide your probes from your meter in along side the wires until you connect with the terminal
itself. You should read between 2 to 5 VDC. If the reading is not within range of that, replace the main
control board.
3. If the voltage checks good, remove the Inverter from the compressor by removing one screw at the bottom
of the Inverter that goes through the bracket that is welded to the compressor. Pull the inverter away from
the compressor. Use a small flat bladed screwdriver to remove plug from compressor terminals. Using an
ohmmeter, check the resistance between compressor terminals (see Testing Compressor). If the compressor checks good, replace the Inverter.

Troubleshooting the Electronic Tumble Action Washer and Dryer:
Washer Fault Codes:
Display shows: F 01
Indicates:
An internal fault in the control.
Correction:
Touch the STOP/CANCEL pad. If the display continues to display F 01 or if the code returns when
the washer is restarted, replace the control.
Display shows: F 02
Indicates:
A water temperature problem.
Correction:
First check to see if the incoming water hoses are connected properly. If so, disconnect both wires
from the water temperature sensor and measure the resistance of the sensor. If the reading is less
than 3K or more than 163K, replace the sensor. If the reading is between 3K and 163K, reconnect
the wires to the sensor and unplug the small four pin plug from the control board. Measure the
resistance between pins 3 and 4 in the plug. If the reading is the same as the sensor reading,
replace the control board. If the meter reading is not the same as that at the sensor, the wiring
between the control board and sensor is defective.
37
Display shows: F 03
Indicates:
Water level problem caused by either no incoming water or the drain pump is not working.
Correction:
Touch the STOP/CANCEL pad to clear the F 03. Check the drum for water. If the drum has a
normal fill of water, touch the Drain/Spin pad and press the start pad. If the water does not pump
out, remove the front access panel and measure the voltage drop across terminals of the drain
pump. If the meter reads 120 VAC, the drain pump is defective or the drain hose is plugged. If the
meter reads zero, disconnect power, remove the large four pin plug (JX) and the eight pin plug (J11)
from the back of the control. Measure the resistance between pin 3 in the four pin plug and pin 3
of the eight pin plug. If the meter reads open, the wires between the control board and the drain
pump are defective. If the meter reads around 15 Ohms, the control board should be replaced.
If the drum does not have water in it, start the washer in the Normal Cycle and select Warm Wash.
If the washer does not fill, make sure the faucets are turned on, unplug one of plugs from the water
valve and measure the voltage drop across the terminals in the plug. If the meter reads 120VAC,
the water valve is defective. If the meter reads zero, measure for voltage from each terminal in the
plug to neutral. If the meter reads zero from each terminal, the pressure switch or the wiring to the
pressure switch is defective. If the meter reads 120VAC from one terminal, the control board or the
wiring from the valve to the control board is defective.
If the washer is over filling, check the pressure switch or the tube to the pressure switch.
Display shows: F 04
Indicates:
The washer is not advancing through it increments.
Correction:
Touch STOP/CANCEL pad to clear the F 04. Select and start the washer in the Heavy Duty wash
cycle with the Heavy Soil/Stain Option deactivated. If the tub does not start turning while filling or
within 30 seconds after the fill is completed, troubleshoot for a motor will not run problem. If the
motor is running and the tub is filled, let the washer run for at least 6 minutes. Measure the voltage
between pin one of the 8 pin connector (J11) and pin 7 of the 7 pin connector (J6). The voltage
should be below 50 VAC when the timer advance is off and line voltage when the timer advance is
on. If the meter reading does not switch between these two readings, the motor speed control is
defective. If the meter reading switches between these two readings, the electronic control board
is defective.
Display shows: F 05
Indicates:
A problem with the key pad.
Correction:
Disconnect the keypad ribbon from the control and reconnect the ribbon. Try all keypad switches
to see they all function correctly. If they do not, then try cleaning the end of the ribbon with a soft
cotton cloth. Reinstall the ribbon and program the washer to operate. If the code reoccurs, replace
the touch pad.
Display shows: ddo
Indicates:
Drawer reed switch is not closed.
Correction:
Make sure the drawer is closed. If the drawer is closed, check that the magnet in the drawer is in
the correct position. If the magnet is in the correct position, check the reed switch.
Display shows: dr
Indicates:
Door switch is not closed.
Correction:
Check that the door is closed and the door catch is not broken. If so, replace the door lock
assembly.

PROBLEM:
The display shows error code F 04 on electronic control tumble action washer which indicates the
washer is not advancing through its increments.
CAUSE:
Faulty electronic control board or motor speed control board.
SOLUTION:
Touch the STOP/CANCEL pad to clear the F 04. Select and start the washer in the Heavy Duty
wash cycle with the Heavy Soil/Stain option deactivated. If the tub does not start turning while
filling or within 30 seconds after the fill is completed, troubleshoot for a motor will not run problem.
If the motor is running and the tub is filled, let the washer run for at least 6 minutes. Measure the
voltage between pin one of the 8 pin connector (J11) and pin 7 of the 7 pin connector (J6). The
voltage should be below 50 VAC when the timer advance is off and line voltage when the timer
advance is on. If the meter reading switches between these two readings, the electronic control
board is defective. If the meter reading does not switch between these two readings, the motor
speed control is defective. The replacement motor speed control MUST be a Generation 2 style
(134149200, 134306000 or a later sub). If the Generation 1 style (131887601 or 131887601GE)
motor speed control board is installed, certain cycles and spin speed may not function correctly.
41
PROBLEM:
Cycle Not Advancing or Timer Stalling Symptoms Update on Tumble Action Washers
CAUSE:
The root cause of washer stalling in cycle (timer not advancing) on horizontal axis washers is
electrical noise generated primarily by the timer contacts opening and closing which can interfere
with proper operation of the speed control board. At times, depending on ambient environmental
conditions, this electrical noise can cause the motor controller board to receive corrupt signals
and remain on “stand by condition” resulting in the cycle not advancing. By manually advancing
the timer to the next step in the cycle or by turning the washer’s power off and on, the electrical
noise is discharged and the washer will perform until electrical noise may happen to interfere once
again.
SOLUTION:
To resolve this issue, three jumpers have been added to the current motor controller board to
reduce electrical noise levels around the microprocessor. Testing has proven this change to the
board significantly reduces occurrence of control lock-up. The motor controller board assembly
with external jumpers is Part Number 134306000, identified by an information label with the number 134058400 Rev C or 134258700 on it. The label may be yellow, orange, red, white, green, etc.
134306000 will replace the following part numbers:
131770700
131887601
134149200
If the SCU 134306000 has been replaced and the timer continues to stall, replace with SCU
131887601GE.
PROBLEM:
Small amount of water spills out on floor when the tumble action washer door is opened after cycle
is completed.
CAUSE:
Water left in the bellows (boot) after the cycle.
SOLUTION:
Order bellows (boot) kit, 5303937187. This kit will contain a new bellows with a drain back feature
(Figure 1), a spring clamp (Figure 2), three tube spacers and a set of instructions. The new style
bellows attaches to the front panel by means of a spring clamp instead of adhesive. (Replaces
5303937140.) See the kit instructions on the following pages.

PROCEDURE FOR REPLACING THE DOOR BOOT (BELLOWS) KIT P/N 5303937187
This tutorial will show you how to do the job, what pitfalls to avoid, and will include some great tips. Some boots are
glued to the front panel and some are attached with a wire spring clamp. Directions for removing and replacing each
type are as follows:
1) If the machine has a Dryer stacked on top, or is positioned in such a way that it would be too much bother to
move, you will be better off leaving it where it is. However, if it is possible, it would be easier to do this job if the
machine could be leaned back against a wall (protect the wall against being defaced though). By leaning it
back, the tubs will hang back from the front panel and you will have increased space to work. If leaning it back
is not possible, then use a 6 or 8 inch block of wood to wedge between the front panel and the tub to hold the
tub back out of the way.
2) If the boot is attached to the lip around the perimeter of the opening on the front panel with glue, use a razor
blade (Figure1) to carefully slice the glued spots on the boot away from the front panel. If the boot is attached
to the lip around the perimeter of the opening with a wire spring clamp, insert a small screwdriver between the
spring and the boot at the six o’clock position (Figure 2). Gently pulling down and out on the spring, continue
to work the wire clamp off the boot (Figure 3).
Figure 2
Figure 1
Figure 3
Figure 4
3) Once the boot is loose from the front panel, push it into the opening of the tub and out of the way (Figure 4). At
this point, if the machine is not leaning back, take your block of wood and while pushing back on the tub
through the opening, wedge the block between the front panel and the tub about ten inches to the bottom - right
of the opening. This will afford you more space to work with the boot.
43
4) You will now notice that the boot is still attached to the duct that is located just inside the front panel at the
upper left corner from the opening. This is where the water, soap, bleach and fabric softener enter the tub. To
remove (and later on, reattach) the clamp holding this in place on the end of the duct you will have to make
yourself a tool from a three inch piece of 3/8 inch soft copper tubing
5) In Figure 5, you will see that the end of the tube is flattened somewhat so that it can be slipped over the twisted
ends of the clamp as shown in Figure 6. Twist the tube counterclockwise to slip the clamp and set both the tool
and the wire clamp aside. Pull the boot free from the duct.
Figure 5
Figure 6
6) Using both hands, grab onto the boot at the top of the opening to the tub and pull downward and toward you with
slow steady pressure. As the boot is pulled free from the outer lip of the tub (at the top), the coiled spring that
holds the boot from the groove behind the lip around the opening to the front shell will become visible. You can
either continue pulling on the boot until it comes off or you can hook the spring (with a piece of coat hanger
fashioned into a hook) and pull it off and then pull the boot off separately.
7) Once the boot is off, examine the lip that extends around the entire perimeter of the front opening of the front
half of the tub (the front half and the rear half are so named because when bolted together, forms the outer tub
that surrounds the inner tub). The boot has a lip that will have to be folded into the groove behind the lip on the
front tub shell. To start this, examine the new boot and locate the groove in front of the lip that corresponds to
the similar lip and tab on the tub shell. It will make this job a lot easier if you can obtain some liquid dishwashing
soap from the consumer, and sparingly lubricate this groove on the boot to make it easier to slip onto the lip of
the tub shell (See Figure 7). No soap is preferable to too much soap. Have a cloth handy to wipe the soap from
your fingers.
Figure 8
Figure 7
44
8) Once the groove in the boot is lubed with soap, locate the arrow as shown in Figure 8 that is located on the top
of the boot (located to the right of the extrusion that slips over the duct). This arrow must point up when the
boot is installed.
9) With the boot in one hand and the other hand spreading the lip and groove (on the boot near the arrow), force
the lip into the groove behind the lip at the top of the opening on the tub shell (Figure 9).
Figure 9
Figure 10
10) With one hand holding the boot so it does not slip off, use the other hand to continue spreading the lip and
groove of the boot further to the right. In this way you continue this action 360 degrees around until the boot is
mounted onto the front tub shell (Figure10). Don’t give up, rest one hand at a time if needed. Whatever you do,
do not remove both hands until the boot is on (unless you want it to fall off and then you get to start over with
it).
11) Now is the time to put the spring back on. Included in the BOOT KIT is a set of three spacers (an example of
which is shown in Figure 11 below). These spacers are to be used to hold the spring in place in the groove on
the outside perimeter of the boot. As it will take both hands to stretch this spring into place, these spacers will
prevent the spring from popping out when you let go of it to use both hands to stretch it further around the boot.
Begin by pushing the spring down into the groove just forward from where the boot contacts the front tub shell
at about the 12 o’clock position. While holding the spring in place with one hand, use the other to tightly wedge
the spacer above it, between the spring (in its groove) and the weight ring above it as shown in Figure 12.
Figure 11
Figure 12
45
12) Working your way to the right, push the spring down into the groove. When you have placed the spring about
90 degrees around the opening from the first spacer, the spring will begin to get tight. Push in another spacer
at that point (making sure to keep checking the first spacer, if it pops out - the spring will pop out).
13) Continue working your way around (while checking both spacers, you don’t want them to slip out) until you
reach 180 degrees from the first spacer. Install the third spacer.
14) The spring will be extremely tight now as shown in Figure 13. Once you have gone more than half way around,
the spring will be easier to roll into the rest of the groove (so long as all three spacers are holding tight). When
you have the spring in place, make sure to remove the three spacers before proceeding to step # 15.
15) Replace the boot extrusion back onto the duct and pull it up over the ridge on the duct near the top of the
opening (Figure 14). Reinstall the clamp in such a way that the clamp sits between the ridges on the extrusion
and above the ridge on the duct. Snap the clamp closed with the copper tubing tool that you used previously.
Figure 13
Figure 14
16) Before attaching the new boot to the front panel, clean the surface where the boot will fit against the front panel.
17) Remount the boot onto the front panel as shown in Figure 15, making sure that the boot is not wrinkled. If large
wrinkles exist, this may pool water in the boot and dribble onto the floor when the door is opened. If this is the
case, pull it loose from the front panel and remount it slightly more clockwise or counter clockwise as needed.
18) Insert the wire spring clamp from the kit into the groove at the top of the boot (Figure 16). Work the clamp into
the groove all the way around the boot making sure the clamp is oriented to the 6 o’clock position. Close the
door to assure proper sealing of the boot to the door. Run the washer to check for leaks.

Top Load & Laundry Center Washers:
New for 2004:
Beginning January 1, 2004, the DOE (Department of Energy) has mandated that all clothes washers meet a
maximum energy usage rating. One of the components used in obtaining this rating is a 70/30 water valve. What
this means is when the water valve is energized in the warm wash temperature setting, the incoming mixture of
water will be 70% cold and 30% hot. This valve will not affect water temperatures on models with an ATC (Automatic
Temperature Control). ATC models have a new control board with non-compliant water temperature settings. On
some models, if a warm rinse is selected, the washer will fill with cold water during rinse, followed by a warm spray
rinse during spin.
On all super capacity model washers (3.0 ft³ wash basket), the pressure switch has been changed to lower the
water level.
Previous models:
High Water Level Setting
13.5 – 15.2 inches
Low Water Level Setting
5.5 – 7.8 inches
New models:
High Water Level Setting
10.8 – 13.0 inches
Low Water Level Setting
4.3 – 6.6 inches

the threads already cut into the plastic door panel before tightening screw.
Check latch cam (hook) making sure it is all the way into the hole in the strike. See Figure 2.
In some cases the door seal may need to be replaced to improve closure.

PROBLEM:
New door latch does not close the same as the original.
CAUSE:
The new Light Touch latch does not have the same opening and closing force as the original. This
is to make it easier for the customer to open and close the dishwasher door.
SOLUTION:
The new latch mounts the same as the original but does not have the square tab on the backside.
It does wire the same however. When installing this new latch the door seal may also need
replacing because of the difference in closing force. See pictures of both latches below. Notice
the new latch has the door switches mounted closer together without the cam spring between
them.

PROBLEM:
Timer stalling in cycle on manual timer models.
CAUSE:
Incoming water temperature.
SOLUTION:
We receive a number of calls for timers stalling or just not completing the cycle. Talking with
servicers on the phone, a number of timers have been changed just to have the customer call back
to say it is still not working. To assist in finding the cause for this problem, here is a procedure you
can follow that can help find the cause for this complaint.
Before you make the trip to the customer’s home it would be a good idea to call them by phone to
have them start the dishwasher for you so it can be getting hot while you are on the way to the
house. It will not be necessary to have the dishwasher loaded with dishes or detergent on this
call. The dishwasher needs to run for about 25 minutes, this will aid you in checking this problem.
When you first arrive, determine from the customer what cycle and options were set at the time of
failure. You will also need to know what position the timer had stalled, as well as for how long the
timer stayed at that location. Next check the water temperature at the sink. This way you will
know how hot the water was when the customer started the dishwasher for you.
With this information it is time to check the dishwasher. First to be checked is the heater and
safety thermostat; both of these are located and checked from underneath. They are on the
bottom, left side of the tub. Check the heater for continuity. You should get a resistance reading
on the heater. The safety thermostat should just read closed. Next reset the controls and
reposition the timer to just before the location the customer found the timer when it had stalled.
After setting the timer and the option switch make sure power is going to the heater to heat the
water. Once this all has been done check the temperature of the water in the tub. The timer
should advance on into the stall. You now need to wait until the temperature rises in the tub to
close the control thermostat. The control thermostat is located under the tub to the right side
behind the junction box.
Shown below is a chart that lists the different control thermostats currently used on dishwashers.
This chart shows the temperature settings of the different thermostats as well as the temperature
of the water in the tub.

Water is heated in the dishwasher by falling back onto the heater as it is being sprayed inside the
tub. The temperature of the water will raise about one degree every four minutes. As the water falls
back onto the heater, then onto the tub the thermostat senses this change in temperature. If you
can watch the water temperature without opening the door you can follow this temperature rise.
Once the water temperature has reached the proper temperature the control thermostat should
close to advance the timer. If the thermostat does not close, take a jumper wire and carefully short
across the control thermostat to see if the timer then advances. If the timer only advances after
shorting across the control thermostat replace this thermostat. If you need to replace the control
thermostat add thermomastic to the head of new part before installing into tub. This will give a
better contact between the thermostat and the tub. When mounting the new thermostat into the
tub make sure it is good and tight in the mounting hole.
If the timer does not advance after the thermostat is shorted out, check the wires from the thermostat to the selector switch, then on to the timer to make sure all connections are good and tight.
The control thermostat only controls the timer motor in the delay cycle, a loose connection can
keep the timer from advancing.

PROBLEM:
Not cleaning the dishes.
CAUSE:
Clean dishes depend on water temperature, amount of detergent used, proper loading of the
racks, and condition of the water (hardness).
SOLUTION:
To find the cause for the dishwasher not cleaning dishes check these items: loading of the racks,
the amount of detergent, temperature of the water, and water hardness. This is a brief over view of
each of these items to give a better understand how these work to clean the dishes.
When loading the racks care must be taken to insure the water can reach the total surface of the
items for the food to be removed. The user’s instructions picture the best way of loading each rack
for proper cleaning. If plates and/or bowls are loaded touching each other, this will prevent water
from reaching all parts of the items in question. Two items touching can also be the cause of other
complaints as well. Each item needs to be placed in the rack so water can be sprayed onto and
run off freely. This will help ensure a clean load. The upper rack loading is more important
because tall glasses and bottles with small openings require a more direct spray from the rotating
spray arm. These items need to be loaded for the spray arm to pass directly underneath them,
where water can be sprayed inside and all the way up to the top of the item to insure it is cleaned
properly. Flatware loaded into the silverware basket needs to be loaded loosely for good cleaning
as well. Do not let the flatware nest together. The more open the items are, the better the cleaning
process.
The detergent used in a dishwasher is specially formulated to emulsify the greases and oils that
bond food soil to the dishes. This detergent is dissolved by hot water, and then sprayed around in
the tub. While cleaning, hot water used to aid the detergent is also working against it. Minerals in
the water can bond with the food which will prevent it from being removed properly. To prevent this
there are additives in the detergent to make the water wetter. This just means that minerals in the
water are being held in suspension so the food can be rinsed off cleanly. Dishwashing detergents
should not suds. This can cause water spots and streaking of the glassware. Finally, care must
be taken that the detergent does not damage the finish of the dishes along with being environmentally friendly. The customer may need to try different brands of detergents to find the one that
works best for them. The proper amount of detergent is important for cleaning and the product
manufacturer will give you guidelines on determining this amount. This is based on how hard the
water is in the customer’s home. When a new dishwasher is installed it is always best to have the
customer start off by actually measuring the detergent. Dishwashers today are using much less
water. Starting off with actually measuring the detergent will give them a better idea as to the
proper amount needed for cleaning.
The importance of hot water to cleaning dishes is essential for cleaning dishes. Hot water must
first dissolve the detergent, then spray the mixture around in the tub to soften and loosen the food
and then rinse the food from the dishes. Water temperature needed to dissolve detergents can
very, but never less then 107° F. To insure this temperature is reached, the incoming water on the
first fill needs to be no lower than 120°F. It is common knowledge that water entering the tub on
the first fill will lose temperature. If this temperature is at or above 120°F at the kitchen sink faucet
it should still be hot enough at the dishwasher to dissolve the detergent for the pre wash. With the
smaller amounts of water being used today to conserve energy this makes water temperature
more difficult to maintain. Consumers may have to change the methods they have used in past for
starting a load of dishes. It becomes necessary to start a wash load by running tap water to purge
cool water from the hot water line before a cycle is started. This will ensure that proper water
temperature can be maintained to the end of the cycle. Using less water per fill, coupled with
water heaters that cannot be adjusted and customers desiring to keep water temperatures below
115°F leads to a problem of not cleaning the dishes. What is a technician to do? The only
alternative is to advise the customer of the cause for their problem, advise them of what needs to
be done, then allow them to make the decision as to how they wish to correct the water temperature problem.
51
SOLUTION (cont):
Water conditions as well as water temperatures can and do change from season to season and
time to time. For this reason water hardness can and may be a factor in wash ability complaints
at different times of the year. This is one condition that may get over looked while determining the
solution to the customer’s complaint.
Some information used in writing this was found in articles listed on the internet site of The Soap
and Detergent Association (www.cleaning101.com).
PROBLEM:
Dishes not dry when cycle ends.
CAUSE:
Several factors involved.
SOLUTION:
For dishes to come out dry requires more than heat from the heater in the bottom of the tub. This
has always been the truth. The reality of this has become more evident today with the need to
conserve energy and resources. A dishwasher that is not drying can be a very complex problem
to solve for the technicians in the field. This article is intended to help find a solution to this
complaint.
What does it take to dry a load of dishes? This list of five items, if worked properly, will result in a
dry load of clean dishes. The importance of each and how they work together follows.

Heat from the heater
Hot water used in cleaning the dishes
Proper loading of the racks and baskets
Rinse aid
Air flow
1. Heat from the Heater
In the past, the heater in the tub has been the primary component for drying in the dishwasher, but
its role has been lessened somewhat by other items today. The heater is first used in dishwashers to maintain and increase water temperature for the main wash and rinses. The heater is first
activated prior to the main wash and will be activated in each fill after. As the water is heated the
dishes will get hotter as well. Once the cycle reaches the dry phase the dishes should be at least
120°F for them to dry. In the dry phase the tub environment will be one of high humidity and steam.
The first few minutes of the dry phase the timer allows the steam to escape with out the heater
being energized. As this phase continues the heater is turned on in a pulsing pattern to force the
steam from the tub. This change of environment allows for the evaporation of the water from the
hot dishes. The dishes start to dry.
2. Hot water used in cleaning the dishes
Hot water is a very important resource used in a dishwasher. Hot water is used to first dissolve the
detergent, then to activate the chemicals in the detergent which are intended to soften and loosen
the food soil found on the dishes. After this has been accomplished the hot water then is used to
rinse this food soil from the dishes. While in the process of cleaning, this same hot water will be
increasing the temperature of both the dishes and the inside of the tub. Earlier model dishwashers
using a high pressure wash system used larger amounts of water in the tub on each fill. The large
volume of water did get the tub and dishes hot quite quickly. Products today are using much
smaller amounts of water to conserve energy and resources, for this reason the incoming water
must be hotter today than in the past. It is important that the incoming water is 120°F each time
the tub is filled. With smaller amounts of water the temperature of this water will decrease very
rapidly, this will affect the performance of the detergent as well as the drying.
52
3. Proper loading of the racks and baskets
Rack and basket loading are as important to cleaning and drying a load of dishes as good hot
water and detergent are. If the racks are not loaded properly food soil cannot be removed from the
dish surfaces. One thing to keep in mind when it comes to loading the racks is, if the water can’t
get to it, it will not come off. Then when you think about drying, if the water can’t leave it, it won’t
dry. The racks and basket must be loaded so the water will sheet off the dishes. If the items are
too close together water will bridge between them and form a pool of water. If water pools it will not
be in contact with the hot surface of the dishes and will not evaporate as it should. The flatware in
the silverware basket can nest together. In this case water actually bonds the pieces together.
Nesting will keep the items from drying but will also keep them from cleaning as well.
4. Rinse aid
Rinse aid in the past was something that was not necessary. However, this is not the case today.
Rinse aid is used to break the surface tension of water so it will spread out over the surface of
dishes in a thin film. This thin sheeting action reduces water spots, keeps streaks from forming
and evaporates the water much faster which improves the drying performance.
Rinse aid is now a necessity due to the lower energy usage of current designed dishwashers.
Previous models relied on high wattage heaters and larger amounts of water to get the dishes hot
enough to dry. This method cannot be used today because of the need to conserve energy and
resources. Drying today uses an evaporation method with the hot dishes. With smaller amounts of
water during the wash and rinse cycles, rinse aids effectively thin the water and allow the hot
dishes to dry themselves.
5. Air flow
Last is air flow. This is both in and out of the tub in the dry phase. The inside of the tub of a
dishwasher will become a very humid environment. For the dishes to come out dry at the end of
the cycle, as much humidity as possible must be removed. This is where the vent and venting
system comes into play. All dishwashers have a vent of some kind for removing the moisture from
the air in the tub. If the vent is to the outside of the tub, there has to be a way to get air in so steam
can be expelled. On most products air is brought into the tub through the bottom of the door. Air
is pulled into the tub, as the steam is released from the top of the door. As the humidity in the tub
is reduced, the water on the hot dishes starts to evaporate. The heater is cycled on basically to
increase the temperature of the incoming air and force the steam out at a faster rate.

Precision Direct Feed Dishwasher:
Wash Distribution System
The wash system consists of a wash pump and motor assembly to provide water under pressure to three spray
arms to loosen and remove food. Water sprayed from these arms will alternate starting first with the bottom arm
then changing to both the center and upper spray arms simultaneously. Water passes through a filter and soil
director to remove food particles so that only clean water is sprayed onto the dishes for cleaning.
The remaining parts in the wash system are the sump assembly which acts as a reservoir for clean water and the
delivery tube to supply water to the upper two spray arms. See Figure 1.
Alternating Wash System
The alternating wash system used in this dishwasher will only spray from the lower arm or the upper set of arms at
a time.
Alternating the spray is achieved with a check ball moving between two holes in the sump. One hole is located in
the rear of the sump for the upper two spray arms; the second is located out the top of the volute cover for the lower
arm. The check ball rests at the end of a ramp molded into the sump partially blocking the rear hole. As water
under pressure enters the volute cover, the check ball is held tightly into the rear hole restricting water flow from this
opening. See Figure 2.
Water is now forced to leave the remaining hole from the top of the cover into the lower spray arm. See Figure 3. The
force of the water entering and leaving the arm causes it to turn. The ball covering the rear hole allows a small
amount of water to enter into the delivery tube. The delivery tube fills with water at a rate of approximately four
inches a minute. This water is used for changing the spray from the lower arm to the upper two spray arms.
Figure 2
Figure 1
Figure 3
54
All wash and rinse cycles start using the lower wash arm. Changing spray from bottom to upper spray arms is
accomplished with the wash pump stopping for not more then .6 of a second. This pause removes water pressure
from the rear of the check ball, allowing the water that has accumulated in the delivery tube to reenter the sump
moving the check ball away from the hole and up the ramp. See Figure 4.
The pump is restarted, water pressure now is against the back of the check ball holding the ball into the top hole.
Water exits out the rear hole into the delivery tube and sends water to the upper spray arms. See Figure 5. Water
is divided in the delivery tube with 80% going to the center spray arm and 20% to the upper arm. Spray will continue
from the upper arms for approximately 90 seconds then the pump will pause for 3 seconds. This allows time for the
delivery tube to completely drain and the check ball to fall back to the bottom of the ramp. The cycle restarts with
water being sprayed from the bottom again.
Delivery Tube

Wash Motors
The direct feed model dishwashers offer two different wash pumps: a single speed wet rotor style motor and a
variable speed DC motor. The style of motor used on a specific model will depend on the features offered. All direct
feed model dishwashers use a separate drain pump for draining the unit.
Single Speed Wet Rotor Motor
This wash pump operates on 120VAC current and has 3 functional parts: a 1/12th hp drive motor, impeller and
macerator blade. This will circulate water at a rate of 12 gallons per minute. This wash pump and motor assembly,
is replaced as a complete assembly. See Figure 6.
Variable Speed Wash Motor
Models with the variable speed motor improves washing for select cycles and loads. The speed of the motor will be
determined by the electronic control based on the cycle selected. The control will monitor motor speed with input
from a Hall Effect sensor that is mounted to the rear of the wash motor. Input voltage for operating the motor will be
120VAC with the motor changing this to VDC with a built-in rectifier. See Figure 7.
Figure 6
Figure 7
55
Spray Arms
The lower spray arm is designed using three extentions that spray water into the lower rack. Each arm also has a
leg on the under side for cleaning the sump filter This spray arm is turned by water pressure in a clockwise direction
at a rate of approximately 40 rpm. All wash and rinse cycles start with water sprayed from the lower arm. See
Figure 8.
The center spray arm is mounted on a short delivery tube to the under side of the upper rack (see Figure 9). The
rotation of this arm will be clockwise at a rate of 20 rpm. The short delivery tube to which the spray arm is mounted
joins up to the rear of the tub with a bellows this allows the upper rack free movement in and out. This end will also
allow the rack to be adjusted up and down on models with an adjustable upper rack. As water enters this delivery
tube, water pressure expands the bellows forming a seal to the rear tub wall.
The upper spray arm located in the top of the tub turns in a counter clockwise direction, and sprays simultaneously
with the center spray arm. This spray arm is threaded to the end of the delivery tube. It is removed by turning the
locking nut counter clockwise. This arm comes as an assembly consisting of an arm and locking nut. The spray
arm will turn at about 40 rpm. See Figure 10.
Figure 10
Figure 8
Figure 9
Stainless Steel Filter
A stainless steel filter covers the entire sump area (see Figure 11). The filter is designed to remove all food particals
from the water so only cleaned water can re-enter the sump. This filter has a fine mesh polyester center basket and
a soil diverter for directing soil trapped by the filter to the rear section of the sump. The spray arm support is used
to hold the filter tightly in place.
Heater
A heater is mounted in the bottom of the tub to increase water temperature during wash and to also assist in drying
the dishes (see Figure 12). The wattage draw of the heater can vary depending on the job it has to perform. When
heating water, the draw can be 900 watts. This wattage will drop to approximately 700 watts in the dry cycle. This
design of the heater provides energy efficiency. Mounted next to the heater on the under side of the tub is a safety
thermostat. This thermostat will open if the temperature in the tub reaches 200°F.
Figure 12
Figure 11
56
Fill System
The fill system of this dishwasher consists of the water fill valve and a safety float switch (see Figure 13). Power
from the control is applied to the water fill valve through the float switch. The water valve is an electrically operated
valve with a flow washer that regulates the amount of water based on the water pressure applied to the valve inlet.
Water pressure needs to be between 20 and 120 psi for the dishwasher to have the proper amount of water for
operation. The float switch will shut off power to the valve if the tub over fills with water. Water enters the tub through
an air gap mounted to the left side of the tub. See Figure 14.
Water valve
Float Switch
Figure 14
Figure 13
Drain Pump
The only function of the drain pump is to remove water from the dishwasher. It is driven by a 1/25th hp drive motor.
It consists of 3 functional parts: pump cover, impeller/armature, and stator. The replacement pump comes as an
assembly. However, the pump cover can be removed for cleaning. The drain pump is mounted directly to the front
of the sump. See Figure 15.
Drying/Venting System
The vent for the dishwasher is on the upper left side of the inner door panel (see Figure 16). Steam and heat exit the
tub during the dry cycle from this vent through a duct between the inner door panel and the outside of the console.
Mounted in this duct is a baffle which is opened and closed by a wax motor. This baffle is normally open. Once a
cycle is started, power is applied to the wax motor actuator by the control. This causes the actuator to close the
baffle and it will remain closed until the dry portion of the cycle is reached. In the dry cycle, power is removed from
the actuator causing the baffle to open. Steam is now released from the tub. This door will remain open after the
cycle is completed until a new cycle is started. The vent duct is mounted with three screws and a self adhesive
gasket. See Figure 17.
Figure 15

Figure 17
Detergent and Rinse Aid Dispensing System
The detergent and rinse aid dispenser consists of two dispensers combined in one housing that are controlled with one wax
motor actuator. The first time the control energizes the actuator
the cover over the detergent side of the dispenser opens dispensing detergent for the main wash cycle. The second time
the actuator is energized rinse aid is released for the final rinse
cycle. The detergent side of the dispenser consists of two cups:
the smaller cup is for detergent used in the pre-wash cycle, the
second larger cup is intended for the main wash. The rinse aid
section has a clear indicator to show the presence of agent in
the dispenser. On models with a digital display, the control will
display an LO when the rinse agent is low in the dispenser.
There is also an adjustable hub inside the dispenser (seen by
removing the cap) to control the amount of agent dispensed.
This detergent and rinse aid dispenser is replaced as a complete assembly. The cap for the rinse aid dispenser is the only
separate part available for the dispenser. See Figure 18.
Dispenser Operation
The dispenser has two detergent cups both covered by
the same cover. In the bottom center of the spring loaded
cover is a thumb release. By pushing up on this release,
the cover will open. The larger of the two cups, under
the cover, is used for the main wash cycle the smaller for
the pre-wash. With the detergent added, the cover is
closed. The cover is slotted so the detergent from the
smaller pre-wash cup can be washed out without the
cover opening. After the fill in the main wash, the control
applies power to the wax motor actuator. See Figure 19.
The plunger of the wax motor extends, pressing down on
a pivot arm attached to the latch for the cover. This releases the cover to dispense the detergent. On the opposite end of this pivot arm is a pin that rides up in the
actuating arm for the rinse aid dispenser.
Wax Motor
Figure 18
Rinse Aid Actuator
Pivot Arm
Figure 19
With power removed from the wax motor, the plunger retracts the pin and the rinse aid actuator falls down the back
side of the actuator. The dispenser is now ready to dispense the rinse aid. The control again applies power to the
wax motor, and as the pivot arm raises the rinse aid actuator the rinse
agent is added into the dishwasher. When power is removed from the wax
motor the pivot arm rises and a leaf spring mounted to the side on the
dispenser forces the actuator arm to the starting position for the next cycle.
Door Latch Assembly
The door latch assembly has two functions: one is to hold the inner door
panel against the door seal around the tub, the second is to open and
close both door switches. See Figure 20.
When the door is closed, a strike mounted on top of the tub forces a spring
loaded catch to rotate back into the latch handle. As the catch makes
contact with the handle, a hook moves up into the strike and locks the
door in place. The rotating of the catch releases the door switch actuator
and allows both door switches to close.
Figure 20
When the door latch handle is raised, the upward pressure on the handle pushes up on the catch that now pushes
back on the door switch actuator which opens the door switches. This pushes the hook out of the strike to allow
the door to open.
58
Thermistor and Soil Sensor Assembly
The thermistor and soil sensor are assembled in the same housing and mounted directly in front of the wash pump
intake. See Figure 21 for location and Figure 22 for closeup.
Thermistor
The control is programmed with preset wash and rinse temperatures for each cycle. The use of a thermistor in the
sump provides water temperature information to the control to maintain these temperatures. The control provides
options for the user to select a higher temperature wash as well as a sanitize rinse.
Soil Sensor
A soil sensor is used to adjust the cycle length based on the amount of food soil found in the water. This sensing
is performed in all wash cycles with the exception of the Rinse only cycle. The sensor, mounted to the under side
of the sump directly in front of the wash motor intake, is made up of a transmitter and a receiver. At the proper time
a light signal is passed between the transmitter and the receiver. The amount of light that is received is then
measured and returned to the control. This information is used by the control to adjust the cycle time.
At the end of the pre-wash, the control stops the wash motor for 30 seconds. This allows the wash water and food
soil to settle for the soil sensor to check the soil level in the water. If no soil is found, the cycle can be adjusted.
The tub is then drained and refilled for the first rinse. At the conclusion of the first rinse the wash motor pauses
again for 30 seconds and the water is rechecked for a change in condition. If no soil is found, the cycle may be
shortened or, if large amounts of soil are found, the cycle may be extended. The control can use either one or both
pauses to adjust the cycle time.
Thermistor
Thermistor/Soil Sensor
Soil Sensor
Figure 21
Figure 22
To ensure the pre-programmed water temperature for the wash cycle is reached, the control can pause the main
wash cycle up to 10 minutes in a Temp assure cycle. This temp assure cycle is automatic and not selected as an
option. If the Hi- temp wash option is selected, the control will pause the main wash section once again for up to 10
minutes to increase the water temperature to 140°F. Whether or not the water temperature is reached in this 10
minute pause, the cycle will continue without indication that it reached or did not reach this temperature. When the
Sanitize option is chosen, the National Sanitation Foundation requires in the final rinse cycle that 155°F be reached
and maintained for a certain amount of time. During the final rinse, the control pauses the time remaining for up to
30 minutes to reach this 155°F temperature before proceeding to the end of the cycle. Should the cycle meet the
requirements defined for the sanitize option, the Sanitize light will come on and stay on until the door is opened. If
the requirements are not met the sanitize light will not come on at the end of the cycle.
59
Electronic Control
All of the functions and operations of the dishwasher are directed and monitored by the electronic control. On some
models the control will adjust cycle times to increase water temperature in the main wash then again in the final
rinse if the temperature is not hot enough to clean properly. Also on select models the control will monitor the
amount of soil loosened from the dishes then increase or decrease the cycle time based on this information.
A cycle is started when the user makes a selection of cycles and options from an electronic keypad or option
switch mounted to the top of the control console. With the cycle selected and started, the control uses sensors to
monitor soil level, water temperature, motor speed, and makes all of the cycle adjustments needed to achieve a
clean load of dishes. Cycles available and options will very depending on model. Models may also have digital
displays for monitoring cycle time or small LED’s for user convenience. When the cycle is completed the control
will display a clean light to inform the user that the cycle has ended, this light will stay lit until the door is opened.
Power to operate the 12VAC control transformer is supplied directly from the dishwasher junction box and is not
affected by door opening.
Wash Cycles
The number of different cycles will vary depending on model. The difference in these cycles can be the number of
washes and rinses as well as differences in assured water temperatures for wash and rinse segments of the cycle.
The control can also restrict the use of certain energy options for a cycle. On models with a variable speed motor,
the proper motor speed is selected by the control for the cycle. The following cycles can be found on those models:
Ultimate Scrub, Pots & Pans
This cycle is intended for heavier soiled dishes. This cycle will be the longest available to the user. It will have the
most rinses along with the highest temp assure water temperature of any other cycle. The high temperature wash
and sanitize rinse are automatically selected and cannot be disabled in this cycle. The soil sensor is used in this
cycle for adjusting the length of the cycle to ensure proper cleaning. On models with a variable speed wash motor
the highest motor speeds will be used in all cycles to remove as much soil as possible.
Normal Wash Cycle
This cycle is used for normally soiled dishes. The control will use the soil sensor to adjust the number of rinses
needed in this cycle to insure proper cleaning. The assured water temperature is automatically select for this cycle
at 135°F for the main wash and 140°F in the final rinse. The user can select a high temperature wash, sanitize rinse
and no heat dry options and can use the delay start in this cycle. On models with the variable speed motor the
control will select the proper motor speeds for both the wash and rinse portion of the cycle.
China/Crystal Cycle
This cycle is used for delicate crystal or china. The fact that these items require special handling, the water
temperature for the wash and rinse cycles will be lower, the main wash temperature will be 125°F and the final rinse
temperature at 130°F. The control will also lock out the water heating options and not use soil sensing in this cycle.
On variable speed models the motor speeds will also be selected by the control.
60
Light Wash/Econo Wash
These cycles are used for lightly soiled dishes. The assured water temperature of 135°F in the main wash and
140°F in the final rinse is automatically selected by the control. The use of all energy options are available and soil
sensing will be used. On variable speed models the proper motor speeds for all cycles are selected by the control.
Rinse Only Cycle
This cycle is for dishes to be cleaned at a later time. The cycle has two rinses. No energy options can be selected,
and no dry cycle.
Upper Rack or Lower Rack Cycle
These cycles are light wash cycles intended for use when only one rack is loaded. Both of these cycles will have
a pre wash, main wash, and one final rinse. Both spray arms will be utilized in each cycle as well. The difference
between the two cycles is the length of the cycle along with the number of times the spray changes between the
arms. The cycle for lower rack will change averaging 60% sprayed from the lower arm and 40% center and upper
arms. The reason for spraying from center and upper arms is to force food down toward the filter. The upper rack
cycle will change averaging 50% from the lower arm to keep the filter cleaned then 50% from the upper and center
arms for cleaning the rack. The control provides assured water temperature in the final rinse of 135°F. The hi-temp
wash and the hi-temp rinse cannot be selected in these two cycles but the no heat dry can be selected.
Speed Clean Cycle
This cycle (on select models) offers a fast wash for light to regular soiled dishes. It has two washes and two rinses
with only a no heat dry energy option available. This cycle does have Temp Assure settings for the main wash of
128°F and 125°F in the final rinse.
Favorite Cycle
This cycle is programmed by the user after selecting a desired Wash cycle with options (if any) and will remain
programmed in the control. Once programmed, the control will repeat the cycle as entered whenever the Favorite
Cycle key is pressed. To program this cycle you make the selection of wash cycle and options then pressing and
holding the “Favorite Cycle” key for three seconds. The Favorite Cycle can be changed by again making your
selections of cycle and options then holding in the Favorite Cycle pad for three seconds.
61
Other Options
Turbo Boost
Models with the variable speed motor offer this option. If selected the motor speed will increase in the wash and
rinse cycles to 3450 rpm to improve the cleaning performance. This option cannot be used in all cycles.
Wash Silencer
Models with the variable speed motor offer this option. If selected the motor speed will be reduced to 2800 rpm to
decrease audible noise in the wash and rinse cycles. This option cannot be used in all cycles.
Delay Start
After a cycle has been selected and before the Start pad is pressed the user can select a delay start option. The
hours of delay can very depending on model and can range from 1 hour to 24 hours in one hour increments. Setting
the hours of delay is accomplished by pressing the delay start pad for the number of hours to delay. After the
number is reached the countdown begins. Once the count down starts, pressing the start/ cancel pad once will
have no effect on the cycle. However, if the start/ cancel pad is pressed a second time in succession, the delay will
be canceled and the cycle will start.
No Heat Dry/Control Lock
This option will disable the heating element during the dry cycle and can be selected at any time prior to the dry
cycle.
The control lock feature enables the user to lock the controls so the cycle cannot be accidentally changed. To lock
the controls press and hold the No Heat Dry key for 3 seconds until the indicator lights. To unlock controls press
and hold the No Heat Dry key for 3 seconds until indicator goes out.
Testing the Control System
There are two tests that can be used on the control system for checking the control as well as the thermistor and
the soil sensor. These tests can be performed from idle and are intended to assist in diagnosing problems in the
control circuit.
62
Water Temperature Test
This test will check the thermistor to ensure it is reading the proper water temperature. Start a cycle and once the
tub has filled with water press the START / CANCEL pad twice. This will stop the cycle and place the dishwasher
in idle. Then press the Start/Cancel and Normal Wash pads simultaneously. The temperature of the water in the
tub will read on the display using the last two digits of the water temperature. If the temperature is greater then 99°F
a decimal point is illuminated along with the 2 digits of the temperature.

Range Information:
PROBLEM:
On the new Frigidaire Slide-in & Drop-in models with serial number NF34xxxxxx and over, how do
you access the switches, EOC, etc?
CAUSE:
No instructions for disassembly.
SOLUTION:
With this new design, disassembly is different than the older Slide-in and Drop-in ranges. Below
are the steps to follow in order to access these components. On some models, the EOC is
attached to the control panel. However, the way to access it is the same.

PROBLEM:
Loose oven door handle, and/or screw strips out of handle core on certain models with serial
VF402 thru VF416, Freestanding Ranges.
CAUSE:
Screw does not fully engage into handle cavity.
SOLUTION:
The screw length has been increased by approximately 3/16” inch to 1-1/2” inches (see Figure 1).
Order two replacement screws part number 316278700. Screw part number remains the same as
original and service parts stock has been purged. Always check the length of replacement screw.
If handle cavity core has been damaged, replace handle.
Figure 1
QUESTION: On gas and electric ranges, what is the U.L. and/or A.G.A. maximum allowable surface temperature?
ANSWER: When Frigidaire tests side panels and doors for skin temperature, certain U.L. and/or A.G.A. guidelines must be followed.
1. Product must be undamaged, correctly assembled and have the correct oven temperature.
2. All skin temperatures are based on a room temperature of 77 F (25 C) and an oven set temperature of 400 F.
3. Oven must be cycling at 400 F for one hour before test is conducted.
4. Pyrometers, (temperature testers), must be of high quality and properly adjusted.
5. An increase or decrease of 1 F in the room ambient temperature, will allow a 1 F increase or decrease in the
maximum allowable surface temperature of the range.

PROBLEM:
Servicers are replacing EOC due to blanking out.
CAUSE:
Electrical noise from lubrication inside door switch.
SOLUTION:
Install new switch. Lubrication has been removed internally. (See 2004 Service Bulletin, Vol. 24,
Issue 2, Page 4.)
PROBLEM:
Painted burner bowls are chipping.
CAUSE:
Bowl supports are too tight.
SOLUTION:
Bend supports to loosen.
PROBLEM:
Many EOCs returned to factory are fully functional.
CAUSE:
Servicer not checking oven sensor circuit.
SOLUTION:
Always check the complete oven sensor circuit from back of EOC through wiring to the oven
sensor. F3 fault code is defective wiring or defective sensor.
67
PROBLEM:
Improper diagnosis of product.
CAUSE:
Lack of basic knowledge for proper diagnosis of range products.
SOLUTION:
Technicians need to have basic service knowledge such as the ability to read schematic and
wiring diagrams, proper use of test equipment and common adjustments found in most Service
Data Sheets attached to products as well as in Service Manuals. Some basic questions received
in TID:
Gas Ranges
How to adjust the simmer flame
How to adjust the standing pilot
Checking oven ignitor amp draw (must be greater than 2.9 amps)
Using a CO detector (take reading after 20 minutes of running)
Electric Ranges
How to properly test the oven sensor circuit (Gas & Electric)
How to properly replace a ceramic element (different wiring for different elements)
Improvements to 30 “ Freestanding Range Products:
Larger oven cavity.
Oven door hinge is now mounted inside door.
Oven door disassembles differently with each glass installed in proper order.
No screws in front when repairs require body side panel removal.
New controls.
Improved reinforcement to drawer with new drawer glide design.
Oven door construction:
The door construction has changed substantially. The door hinges had previously been
mounted in the chassis. The new construction moves the hinges to the interior of the door.
To remove the door, a locking lever on the hinge is lowered to
the unlock position. The door can then be lifted off by opening
the door about 10° and lifting it off of the roller pins.
The door can be returned to the unit by hooking the hinge arm
back on the roller pins and moving the locking lever up to its
locked position.
68
Hidden bake element:
Several models in the new line-up will include a feature called hidden bake. The bake element is hidden beneath the
oven bottom. The bottom is held in place with two thumb screws at the rear. When the oven bottom is removed, the
element can be serviced in the usual way.
Leveling legs relocated:
The front leveling leg has been moved forward and is now mounted on the face of the chassis. This allows for easier
adjustment and improves performance. The rear leveling leg features heavier construction and is also a new part
number.
69
Body Side Panel Attachment:
Changing the body side panel still requires the
removal of screws along the top and rear flanges.
There are two new hidden fasteners that must now
be addressed. The first is a screw on the inside
flange of the body side just behind the face of the
chassis. The picture at the right shows a rear view
of only the oven chassis and side panel. The
hidden screw is indicated by the red arrow.
The second hidden fastener is located further down
this same flange. The diagram below has the oven
removed to reveal the location of the fastener. A
plastic retainer is screwed to the side of the
chassis. A square opening in the side panel hooks
on the underside of the fastener. The last step in
removing the side panel is to raise the chassis and
allow the side panel to slip out from beneath the
fastener.
70
Cooktop lockout feature:
A cooktop lockout feature will be present on some models. A button on the control is used to activate the lockout
feature which will prevent all surface elements from being accidentally turned ON. This feature will only lock the
cooktop. Once the cooktop feature is activated, any attempt to start a cooktop element will sound a warning with
3 beeps and the elements will not turn ON. This feature may generate some service requests for customer instruct.
To turn the cooktop lockout feature ON:
1. Be sure all surface element controls are set to the OFF position.
2. Press and hold until one beep is heard (about 3 seconds). If a triple beep sounds instead, check all surface
elements and turn them to the OFF position and repeat this step. The cooktop locked indicator light will turn
ON and the cooktop controls and functions are locked out until the cooktop is unlocked.
To turn the cooktop lockout feature OFF:
1. Be sure all surface element controls are set to the OFF position.
2. Press and hold until one beep is heard (about 3 seconds). If a triple beep sounds instead, check all surface
elements and turn them to the OFF position and repeat this step. The cooktop locked indicator light will turn
OFF and the cooktop may be used normally.
NOTE: Starting a self-clean cycle will also turn ON the cooktop lockout feature. The cooktop will remain locked
until the self-clean cycle has completed and the oven door has unlocked. If a power failure occurs after the
cooktop lockout has been activated, you must turn OFF the cooktop lockout feature before being able to use the
cooktop features again.
New Oven Control Feature Descriptions:
The following function definitions define the key sequences associated with the function, and provide additional
details on its operation:
Clean Modes – The following clean modes are provided with the corresponding controls:
Speed Clean – A fixed 2 hour duration clean function activated by selecting the “Speed Clean” function, then
either the Start key (if high-end Frigidaire), or one of the slew keys (the duration can NOT be altered by
additional slew keys). After the 1st key activation, the time digits are to display “—-“, then the corresponding
duration is displayed after the 2nd key sequence.
Clean – A fixed 3 hour duration clean function activated by selecting the “Clean” function, then either the Start
key (if high-end Frigidaire), or one of the slew keys (the duration can NOT be altered by additional slew keys).
After the 1st key activation, the time digits are to display “—-“, then the corresponding duration is displayed after
the 2nd key sequence.
Maxx Clean – A fixed 4 hour duration clean function activated by selecting the “Maxx Clean” function, then
either the Start key (if high-end Frigidaire), or one of the slew keys (the duration can NOT be altered by
additional slew keys). After the 1st key activation, the time digits are to display “—-“, then the corresponding
duration is displayed after the 2nd key sequence.
Delay Clean – All the above clean options can be delayed (just like any other cooking, non-broil function) to a
later time using the “Start Time” key. The user simply programs the clean function (as described above), then
programs the delay time using the “Start Time” key. Just like any other delayed cooking function, the control
must accept either programming order for implementing the function (i.e. Enter the start time, then the clean
function, or visa versa). After a delay clean function is programmed by the user, the control MUST lock the
cavity door at program time, not at the start time. Similar to a delayed cooking function, the “CLEAN” and
“DELAY” ICONs must be illuminated after programming takes place.
71
Convection Convert – This function will adjust the set temperature entered by the user for a normal bake operation by a fixed value (typically 250 F). This value should be adjustable via the alteration of the EEPROM. After the
user programs a normal bake or timed bake cooking function, the user will simply press the Convection Convert
button to activate the function. After activation, the user will witness the set temperature being decremented the
fixed amount in the temperature digit locations.
If the user has programmed a convection convert timed cooking function, at 75% of the timed duration (down to the
minute resolution), the control will generate an audio end of cycle tone sequence, and the temperature digits will
illuminate “CF” for the remaining 25% of the timed cook duration. The “CF” will indicate to the user to Check their
Food. The audio end of cycle tone sequence will occur 5 times total during the last 25% of the timed cooking
duration, including the 75% point, and the end of timed cooking cycle. An active Convection Convert function will
NOT alter the overall timed cooking parameters entered by the user.
If the user activates the Convection Convert function after entering a normal bake recipe, and the bake recipe calls
out a temperature too low for the convection convert process, the control will reject the request with the normal key
error code audio message. For instance, if the user enters a normal bake recipe with a set temperature of 315 F,
the converted temperature of 285 F would be below the minimum 300 F convection bake or roast cooking limit, and
the control will reject the request.
Favorite Setting – This function is used to store 1 or more normal bake cooking recipes when a dedicated key is
assigned to the function. This function can be used to store stand-alone bake operations or timed bake operations.
This key cannot be used to store delayed baking functions, nor can it store a convection convert setting. These
functions can be added manually after a favorite setting is recalled. If the control contains a numeric key pad (a
higher-end control), the control will store/recall 3 favorite settings.
To activate the storage of a Favorite Setting recipe, the user will first press the “Favorite Setting” key followed then
by choosing which favorite setting number to be stored by pushing 1, 2 or 3. They will then enter the desired normal
bake cooking program. When the final portion of the program is entered, the user is to press and hold the “Start”
key for 3 seconds. If the control does not have a start key (hence slew keys), the user will simply press & hold the
“Favorite Setting” key for 3 seconds after the last portion of the recipe is entered.
To recall a stored Favorite Setting, the user simply needs to press the “Favorite Setting” key and then press start.
If the control has the capability of storing more than 1 recipe, the user can select 1, 2 or 3 using the numeric
keypad, then press start. For the 2nd key step on a slew based control, the user simply needs to activate one of the
slew keys to start the previously stored favorite setting. No factory default recipes will be provided with the oven or
free-standing range.
To remove or clear an existing recipe, the user simply needs to start the recall process by activating the “Favorite
Settings” key, then pressing cancel. If the control has the capability of storing more than 1 recipe, the user can
select 1, 2 or 3 using the numeric keypad, then press cancel.
Keep Warm – This feature can be implemented as a “stand alone” feature, or can be part of a cooking program
after a timed cooking function. The function can not be activated prior to a delayed start cooking process.
When activated by the user (by pressing the corresponding “Keep Warm” key, then pressing “Start” or a slew key)
the control is to maintain a minimum cavity temperature of ~ 170 F (fixed set temperature must be adjustable via an
EEPROM value) for the duration of the operation. During active operation, the letters “HLd” will be displayed on the
temperature digits for the corresponding cavity. An active Keep Warm operation cannot exceed 3 hours duration.
Sales Demo mode – This control feature (when activated) will configure the entire control to act like a normal oven
to the user, however the control will not fire any relays to any high-current loads, for both cavities. The default mode
is non-sales demo mode. Selection of this mode is only possible during the 1st 30 seconds after a power-up
condition. When the control is in sales demo mode, the display will have to flash “Sd” on one of the displays for ~
1 second, every 30 seconds.
72
To select the function, the user simply has to activate the “Cook Time” key continuously for over 12 seconds during
the 1st 30 seconds after power-up. The display will indicate the present mode by displaying a “Sd” or “–“. If the
control has slew keys, then the user can toggle between the 2 states using the slew keys. If the control does not
have slew keys, the user selects between the 2 modes using the “Clean” key. If no slew keys are present, the
selection is saved by activating the “Start” key. If slew keys are present, then the selection is saved by a key
timeout condition.

Service Data Sheet for the ESEC 10R Electronic Surface Control System:
SERVICE DATA SHEET
- This service data sheet is intended for use by persons having electrical and mechanical training and a level of
knowledge of these subjects generally considered acceptable in the appliance repair trade. The manufacturer cannot be
responsible, nor assume any liability for injury or damage of any kind arising from the use of this data sheet.
NOTICE
SAFE SERVICING PRACTICES
To avoid the possibility of personal injury and/or property damage, it is important that safe servicing practices be observed. The following
are examples, but without limitation, of such practices.
1.
2.
3.
4.
Before servicing or moving an appliance remove power cord from electrical outlet, trip circuit breaker to OFF, or remove fuse.
Never interfere with the proper installation of any safety device.
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 potential safety hazard.
Prior to returning the product to service, ensure that:
• All electric connections are correct and secure.
• All electrical leads are properly dressed and
secured away from sharp edges, high-temperature
components, and moving parts.
• All uninsulated 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 reassembled.
ELECTRONIC SURFACE ELEMENT
CONTROL (ESEC) - This range is equipped with an
Electronic Surface Element Control (ESEC), which
precisely controls the smoothtop cooking elements at
multiple settings. (The Warming Zone element is not
controlled by the ESEC). For the user, the elements are
operated in the same way as with conventional controls,
by pushing in and turning the knob to the desired setting.
The setting is shown in the digital display above the
knob, instead of using graphics on the control panel.
ESEC Hot Element Indicator ("HE") - While an
element surface is hot, that element's display will show
"HE". This is in place of the usual hot surface indicator
light on ranges with conventional controls.
ESEC Lockout Feature ( "- -" ) - The electronic oven
control's Clean and Lock features will not operate when
a surface element is ON. Conversely, the surface
elements controlled by the ESEC will not operate when
IMPORTANT
DO NOT REMOVE THIS BAG
OR DESTROY THE
CONTENTS
an oven control Clean or Lock mode is active. When the oven control is in
a Clean or Lock mode, "- -" will appear in the ESEC displays to signify that
the surface elements are locked out. NOTE: The "HE" (hot element) display
will always have priority over the "- -" display.
ESEC System Components - The ESEC system consists of a Power
Board (main control board mounted on the mainback of the range) and User
Interface Board or UIB (circuit boards with digital displays, mounted in the
coontrol panel), four Potentiometers (push-to-turn control for each element)
and the ESEC Harness that connects the boards and the oven control. The
ESEC boards communicate with each other to control the elements and with
the oven control for the lockout modes. (See the ESEC System Diagram.)

Room Air Conditioner Information:
PROBLEM:
A very low percentage of room air conditioners 25K BTU (FAS256N2A) and 29K BTU (FAS296N2A)
units built for the 2004 selling season have exhibited fan motor vibration which can cause breakage of its own bracket.
CAUSE:
This is not a safety issue! In some situations (only when line voltage is over 240 volts and the
unit’s fan speed is set at 99% or Max), the fan motor will not start smoothly, which will eventually
cause the fan motor bracket to break. If this happens, it will most likely occur in the first usage.
SOLUTION:
We have established a kit to resolve this issue. Please utilize kit 5304440661 (Motor with Capacitor) in place of part number 309630616 (Fan Motor). All orders that you currently have with EHP
for part number 309630616 will sub to the kit number 5304440661. This kit includes a new
capacitor, PN 309908001. This new capacitor can be purchased separately as well and included
with any current inventory of the fan motor.

Motor & Capacitor Kit (Use kit when replacing the motor or if the motor in
unit is OK, just add the capacitor.)
1. Remove two screws on the top of the cabinet.
2. Pull chassis out of cabinet.
3. Remove the screw on the plastic enclosure.
4. Remove three screws on the top and one on the front of
the metal top cover. Place the top cover to the side.
5. Remove the capacitor clamp mounting screw.
6. Disconnect the white wire leading from the motor to the
capacitor (position “C”).
82
7. Connect the red jumper wire (p/n VR008N4K6) “U”
type terminal to the capacitor (position “C”), and
connect the other end terminal to the additional
capacitor supplied with this kit (any terminal on the
2.5uf, 450V, p/n 455000101).
8. Connect the wire wire again which was disconnected at step 6 to the red jumper wire “U” type
terminal at the capacitor “C” position.
9. Connect one terminal of the black jumper wire (p/n
VB008N4N4) to the “FAN” position on the capacitor, and the other end to the opposite terminal used

A third-party vendor, Sure Heat Manufacturing, will provide parts and warranty service for these grills. Service
requests for the 57” Electrolux ICON™ stainless grill will be channeled through the 1-877-4ELECTROLUX (877-4353287) phone number. Calls for the Frigidaire stainless grills will be channeled through the Frigidaire support number,
which is 800-320-0859.
Servicing dealers and service companies should note that any and all calls for service on either the Electrolux
ICON™ or Frigidaire grills must be pre-authorized by SureHeat. Call the Frigidaire support number (800-320-0859)
prior to completing service. Otherwise, any claim for payment will be rejected. Servicing dealers who would like to
