The Whirlpool 12001937 Refrigerator Defrost Thermostat Kit monitors evaporator temperature and controls the defrost heating circuit within cooling system. It is installed near the evaporator where it connects with the heater wiring & responds to temperature changes around the coil. When the evaporator reaches the thermostat's specified temperature, its contacts change state to regulate power to the defrost heater. This allows frost accumulation to be removed without continuously energizing the heater. The thermostat then changes state as the temperature returns to the required range, coordinate defrosting with the cooling system's normal operation.
