Whirlpool WP2321800 Refrigerator Bimetal Defrost Thermostat
Product Description
The Whirlpool WP2321800 Refrigerator Bimetal Defrost Thermostat is a little but important component that keeps your refrigerator running smoothly. It operates as an automatic switch, controlling the defrost cycle. As frost forms on the refrigerator's evaporator coils, the bimetal defrost thermostat detects the growing temperature. When it reaches a predetermined limit, the thermostat turns on the defrost heater. This heater melts frost, allowing the refrigerator to retain peak chilling performance. When the temperature drops after the defrost cycle, the bimetal defrost thermostat resets and shuts off the heater to be ready for the subsequent frost cycle. A defective defrost thermostat can cause excessive ice formation, lowering cooling effectiveness, increasing energy usage, and even spoiling your food.
