The Defrost Bi-Metal Thermostat is an OEM part for Whirlpool refrigerators. It is designed to monitor and control the temperature within the defrost system, ensuring that the defrost heater turns on and off at the correct times to prevent the evaporator coils from becoming too cold and excessively ice-bound. A bad defrost bi-metal thermostat can occur due to wear and tear over time, electrical failures, or exposure to high temperatures. If the thermostat fails, it can prevent the defrost system from functioning properly, leading to ice buildup and reduced cooling efficiency.
