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.

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.

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. The defrost control motor/cam mechanism 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.
