Refrigerator Bimetal Defrost Thermostat

Whirlpool manufactures a range of products, including those under the Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral brands. Additionally, they produce items for Sears-Kenmore and Ikea. The Defrost Bimetal Thermostat is an OEM part designed for Whirlpool refrigerators. It functions as a safety thermostat, regulating the temperature during the defrost cycle.

- The refrigerator runs continuously without cycling off
- Frost accumulation on the evaporator coils, reducing cooling efficiency
- The refrigerator or freezer compartment is too warm
- Irregular temperature fluctuations in the refrigerator

This part addresses the following issues:

- Frost buildup
