Control and Operation
The temperature controls in the built-in refrigerator/freezer are designed to regulate temperature more
accurately and operate the product more efficiently than freestanding side-by-side refrigerator/freezers.
Freezer Thermostat Control
The freezer thermostat controls the temperature of the freezer compartment be sensing cold air coming
from the cold air duct on the back wall of the freezer liner. The thermostat’s sensing tube is located in the
upper right side and upper back of the freezer compartment and is covered by plastic wiring covers
When the thermostat calls for cooling, the following components are energized:
• Compressor
• Condenser
• Defrost Timer Motor
• Freezer Side Panel Heater
In addition, the thermostat sends a signal to the electronic control board indicating that the compressor is
running. The electronic control board then energizes the evaporator fan motor. Although the evaporator
fan motor is energized independently through the electronic control board, it always runs when the
compressor is operating. This insures air circulation across the evaporator coils and through the freezer
compartment during the compressor “on” cycle.
Refrigerator Electronic Temperature Control
The refrigerator electronic temperature control system consists of a thermistor and an electronic control
board. The flexibility of the electronic control enables the refrigerator to operate with greater efficiency
by activating the motorized air door and the evaporator fan motor independently of the compressor
circuit.
