Wiring: Schematic ---VCBB Bottom Freezer -Refrigerator---

Refrigerator and Freezer Compartment Theory of Operation: If both freezer and fresh food thermistors are

warm, their resistance drops (see table Refrigerator and Freezer Thermistor in Temperature Control Section) and the

electronic signals for compressor / condenser fan motor operation and for operation of fresh food and condensate

evaporator fans. After freezer thermistor cools sufficiently to raise resistance and block the signal to the electronic

control, compressor / condenser fan motor will shut off. However, fresh food and condensate evaporator fans will

continue to run until fresh food thermistor cools and signal is blocked to electronic control. If fresh food thermistor

cools before freezer thermistor, electronic control will interrupt circuit to fresh food and condensate evaporator fans

while evaporator fan motor will continue to operate under control of freezer thermistor.
