Operating Characteristics
Note:
Refer to Component Locator Views.
Refer to Schematics.
Component Description
The compressor and dryer are located in the
machine compartment at the bottom, rear of the
unit. The condenser is located under the unit. The
evaporator is located in the freezer compartment
on the back wall.
The capillary is soldered to the compressor
suction line. The capillary is also taped to the
suction line near the dryer. This arrangement
serves as a heat exchanger.
The temperature control and defrost control are
located in the control console. The control
console is located in the top of the fresh food
compartment. The evaporator fan is located in the
freezer compartment behind the air tower.
operates only when the temperature control
(switch) is closed. After 8 hours of motor/cam
mechanism runtime in cooling mode, the defrost
control switches to defrost mode. The defrost
control will stay in defrost mode, providing 115 VAC
to the heater for 30 minutes of motor/cam
mechanism runtime. The defrost thermostat
switch is mounted on the evaporator and, when
closed, completes the neutral side of the defrost
heater circuit. The defrost thermostat switch
opens when the evaporator temperature raises to
58 °F and closes when the evaporator temperature
lowers to 28 °F. The defrost thermostat switch
typically opens during the defrost cycle, preventing
the heater from defrosting for the full 30 minutes.
The purpose for the 30-minute defrost mode at the
defrost control is to prevent the compressor from
operating and refreezing any water that may be
dripping from the evaporator.
Electrical Operation
The power source provides 115 VAC to the
temperature control. The temperature control is a
thermostatic switch that closes when the fresh
food compartment temperature is higher than the
control setting. When closed, the temperature
control provides 115 VAC to the defrost control.
The defrost control contains a motor/cam
mechanism that switches the defrost control
between defrost mode and cooling mode. When
in cooling mode, the defrost control provides
115 VAC to the compressor, condenser fan, and
evaporator fan. The compressor, condenser fan,
and evaporator fan should always operate at the
same time.
Defrost Operation
The automatic defrost function is controlled by the
defrost control. The defrost control contains a
motor/cam mechanism that switches the defrost
control between defrost mode and cooling mode.

Airflow
Freezer Compartment
Cold air from the evaporator is forced up against
the top of the freezer and the back of the
evaporator cover. It is then discharged through
– 5 –
slots along the air tower at the rear of the freezer
compartment.
Air is circulated by the evaporator fan throughout
the freezer compartment, where it picks up heat
and moisture. The evaporator fan then draws the
warmer, moisture-laden air through return louvers
in the bottom of the evaporator cover. The air is
then drawn through the evaporator where heat is
removed and moisture is deposited as frost.
GEA01143
Fresh Food Compartment
Some of the cold air that is being forced against
the top of the freezer and back of the evaporator
cover is diverted through the lower portion of the
freezer air tower and is pushed through the mullion
hole into the damper (in control console).
Air circulates throughout the fresh food
compartment, picking up heat and moisture. The
air is then returned to the evaporator through the
return air ducts located at the top right and left of
the fresh food compartment.

Door Gasket
Top Hinge
The fresh food and freezer doors have magnetic
gaskets that create a positive seal to the front of
the steel cabinet. The magnetic door gaskets are
secured to the fresh food and freezer doors by a
barbed edge that locks into a retainer channel.
GEA01150
1. Starting at any corner, pull the old gasket out of
the retainer channel.
2. Soak the new gasket in warm water to make it
pliable.
3. Push the barbed edge of the gasket into the
retainer channel.
Doors
Vent Holes
GEA01138
The doors are of one-piece construction with foam
insulation. One-piece construction provides
superior thermal performance and reduces air
infiltration. During manufacturing, the doors are
filled with hot foam insulation. This may cause
slight distortion or ripples in the inner door liner.
This is a normal condition and is the result of the
insulating process. This process requires doors
to be equipped with vent holes that allow air to
escape when the door is filled with foam. A small
amount of foam may be visible around the vent
holes.
The inner door panels and outer door panels
cannot be separated and must be replaced as an
assembly.
Freezer Door
1. Remove all food from the inner door liner.
2. Remove 2 screws and the top hinge from the
cabinet.
Note: Do not lose plastic washers on center
hinge pin. Plastic washers are needed for proper
door adjustment.
3. Open the door and lift it off the center hinge pin
to remove.
