Introduction
This manual covers service information for the Bar Refrigerator with Icemaker.
The temperature setting for the refrigerator is factory set at 38°F. The ambient temperature range is
from 70°F to 90°F.
The leveling legs are factory installed. The evaporator is located behind the evaporator cover of the
freezer compartment, and is not serviceable. The wooden front on the full extension drawer can be
stained to match the surrounding cabinets. Please read the Installation Instructions manual for all
pertinent installation information.
The refrigerator can be installed as a built-in or free-standing unit. It can be closed in on the top and
three sides, as long as the front is unobstructed for air circulation and there is proper access to the
door. The door features a cam riser on the door hinge for self-closing. The refrigerator comes with an
optional stainless-steel toe kick taped to the rear of the unit.

Control Features
Throughout this manual, features and appearance may vary from your model.
Temperature Control
Factory Settings Control Range
38°F 34°F - 45°F
The temperature display shows the actual
temperature of the refrigerator. The actual
temperature may vary slightly from the set
temperature based on factors such as door
opening, amount of food, and room temperature.
To change the temperature setting, press the
WARMER or COLDER pads until you reach the desired
set temperature. After 5 seconds, the display will
return to the actual temperature. Allow 12 to 24
hours for the refrigerator to reach the temperature
you have set.
Cleaning the Outside
Door Handles and Trim
Clean with a cloth dampened with soapy water.
Dry with a soft cloth. Keep the outside clean.
Wipe with a clean cloth lightly dampened with
mild liquid dish detergent. Dry with a clean, soft
cloth. Do not wipe the refrigerator with a soiled
dish cloth or wet towel. These may leave a
residue that can damage the fi nish. Do not use
scouring pads, powdered cleaners, bleach or
cleaners containing bleach, these products can
scratch and damage the fi nish.
Stainless Steel
To preserve and protect the fi ne fi nish, regularly
clean and polish the stainless steel exterior and
handle with a commercially available stainless
steel cleaner, such as Stainless Steel Magic™.
Stainless Steel Magic™ is available through GE
Parts and Accessories, 800.626.2002 or GE
Appliances.com. Order part number WX10X15.
Child Control Lockout
The child control lockout feature prevents
unwanted changes to the temperature settings.
After the desired temperature is set, the
temperature can be locked. To lock, press the
+ and - pads simultaneously for 5 seconds. To
unlock, press both pads simultaneously again for
5 seconds.
Refrigerator ON/OFF
This pad stops cooling in the refrigerator, turns off
the temperature controls, and removes power to
the light circuit.
Press this pad for a minimum of 3 seconds to
turn the refrigerator OFF for long
vacations or absences, or when
cleaning the unit or changing the
light bulb. Press the pad again to
turn the refrigerator ON.
To avoid damaging the stainless steel, wipe in
the same direction as the grain when polishing or
cleaning any stainless steel surface. Do not use
appliance wax or polish on the stainless steel.
Warranty does not cover damage due to improper
cleaning methods.

Icemaker
The icemaker will produce seven cubes per
cycle - approximately 100 to 130 cubes per day
(approximately 4.8 lbs). Ice rate is dependant
on freezer compartment temperature, room
temperature, number of door openings, and other
use conditions.
The icemaker will fi ll with water when it cools to
15°F (-10°C). A newly installed refrigerator
may take 12 to 24 hours to begin making ice
cubes.
The icemaker will make a buzzing sound each
time it fi lls with water. Be sure nothing interferes
with the sweep of the feeler arm.
Full Extension Drawer
To remove the full extension drawer, pull the
drawer out to the STOP position. Push the tab on
the right rack guide down while pulling the tab on
the left rack guide up, and pull the drawer out.
To replace the full extension drawer, insert the
sides of the drawer back into the guides and
push until the tabs snap into place. Make certain
the tabs on the drawer are fully engaged before
loading. Pull the drawer out all the way to the
STOP position and push back in several times to
make sure locking tabs are properly engaged.
Troubleshooting
If ice cubes get stuck in the icemaker, the green
power light will blink. To correct this, set the
icemaker power switch to O (off) and remove the
cubes. Set the icemaker power switch to I (on) to
restart the icemaker. After the icemaker has been
turned on again, there will be a delay of about 45
minutes before the icemaker resumes operations.
Note: In homes with lower-than-average water
pressure, the icemaker may cycle multiple times
when making one batch of ice.

Interior Lights
Run diagnostic mode 22 and 21 to test the light
circuit and reed switches. (See Diagnostics and
Service Information
A single 15-watt lamp recessed in the back wall of
the fresh food compartment provides light to the
interior. The light is activated by 1 magnetically
operated reed switch located on the logic board.
The reed switch is not serviceable.
Note: The door reed switch magnet is part of the
door and is not serviceable.

Power Supply Board Replacement
The replacement power supply board comes
with 4 jumpers. The jumpers must be moved to
the correct confi guration for the refrigerator to
function properly. All boards come with a jumper
in the J4 location.
WARNING: Jumper positions should be changed
with the power off.
1. Remove the jumper from J4. If the jumper is
not removed from the J4 position, the control
will display JPS when the power is reapplied.
2. Set jumpers to the confi guration shown below.

The evaporator fan is a variable speed 12-VDC
fan. As cooling demand increases, voltage and
fan speed increase. The fan shuts off when the
door is opened and resumes when the door is
closed.
Evaporator fan voltage should be approximately
5 to 12 VDC at K13 on the power supply board.

•
The damper is cycled based on inputs from
the fresh food and freezer thermistors.
•
The damper opens when the fresh food
thermistor temperature is 1.5 degrees above
the logic board set point, and closes when it is
within that range.
•
The damper opens anytime the refrigerator
door is open except during defrost.
•
The damper cycles 24 times (cycles open and
closed every 10 seconds for 4 minutes) after
defrost when the compressor fi rst comes on.
Check for approximately 18 VDC at K6 on the
power supply board between pin #1 and pin #2
(damper in the closed position), and pin #2 and
pin #3 (damper in the open position). Check for
resistance of approximately 10 Ω at K6 on the

The termination temperature for the defrost cycle
is 45°F at the evaporator thermistor.
The defrost heater and fi ll tube heater are
supplied with 120 VAC only during the defrost
cycle. The fi ll tube heater is in parallel with the
defrost heater, and both are in series with the
fuse link. Check for 120 VAC at K4 on the power
supply board while the unit is in test mode 14.
To remove the defrost heater:
1. Disconnect the defrost heater at the plug-in
connector.

To access the defrost heater and/or fi ll tube
heater, remove the evaporator cover (see
Evaporator Cover).
The defrost heater is rated at 100 watts and has a
resistance value of 121 Ω.
This fi ll tube heater is rated at 3.5 watts and has a
resistance value of 3.8K Ω.
To remove and replace the fi ll tube heater:
1. Disconnect the fi ll tube heater at the plug-in
connector (see photo).
2. Cut the heat-shrink tubing from the fi ll tube
heater.
3. Slide the fi ll tube heater from the fi ll tube as
shown.
2. The evaporator heater is held in place by
metal tabs on the drain trough. Carefully
lever-open the metal tabs as shown.
