Whirlpool W10860146 Refrigerator Defrost Bimetal

The Whirlpool W10860146 Refrigerator Defrost Bimetal is a small but important part of your refrigerator's defrost system. It functions as a temperature switch, automatically starting and stopping defrost cycles to prevent frost accumulation on the evaporator coils. This bimetal is made of a bond between two different metals. As the temperature in the freezer rises, the bimetal strip bends due to the metals' different expansion rates. The defrost heater melts any accumulated ice by turning on when a predetermined temperature is reached thanks to the bimetal. Turn off the heater and let the defrost cycle come to an end once the desired temperature is reached once more. This automatic defrosting procedure keeps your refrigerator operating efficiently by preserving appropriate airflow and avoiding excessive consumption of energy.
