Whirlpool 4388932 Refrigerator Adaptive Defrost Control Board Kit
Product Description
The Whirlpool 4388932 Defrost Control, commonly known as a defrost timer, is an essential component for refrigerators. It is essential to the automated defrost cycle because it keeps the freezer compartment from becoming overly frosty. The evaporator temperature is used by this electronic timer to determine when to start a defrost cycle. The timer transmits a signal to turn on the defrost heater and turn off the compressor during the defrost cycle. Any ice that has built up on the evaporator coils is melted by this heater. The timer initiates regular cooling operation by signaling the compressor to turn back on and the defrost heater to turn off when the evaporator reaches a predetermined temperature.
