WP10442411 Whirlpool Bimetal Defrost Thermostat

The Bimetal Defrost Thermostat is a genuine OEM replacement part designed to manage the defrost cycle in various Whirlpool refrigerators. This component is just over an inch in length and comes with about six inches of wire. It functions by engaging the heater circuit to start the defrost process and disconnects once the temperature exceeds 55 degrees Fahrenheit. The circuit reactivates when the temperature falls back to 20 degrees Fahrenheit.

This design ensures that the unit heats up intermittently to remove frost without warming the refrigerator's contents. It protects the evaporator coil from getting too hot during the defrost cycle, thereby enhancing the efficiency and durability of the refrigerator. The thermostat is suitable for several models from Whirlpool and its affiliated brands such as Amana, KitchenAid, and Kenmore.

Common issues that this part addresses include:
- Inability of the freezer to defrost
- Accumulation of frost
- Overly warm refrigerator
- Refrigerator operating longer than necessary

Whirlpool manufactures this part not only for its own appliances but also for Sears-Kenmore and Ikea models.
