Refrigerator Defrost Thermostat

Whirlpool's product line includes brands such as Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. Additionally, Whirlpool manufactures items for Sears-Kenmore and Ikea. The Defrost Bimetal is an essential OEM component for Whirlpool refrigerators. It serves as a safety thermostat within the freezer's defrost system, monitoring and managing the evaporator coils' temperature during the defrost cycle to prevent overheating. By shutting off the defrost heater when the coils reach a specific temperature, this part ensures the refrigerator’s defrost system operates efficiently.

Signs of a malfunctioning defrost bimetal include:

- Frost accumulation on the evaporator coils that remains after defrost cycles
- The refrigerator or freezer section becoming too warm
- The refrigerator compressor running continuously

Common reasons for bimetal failure are corrosion, prolonged exposure to extreme temperatures, and general wear and tear, which can impair its ability to respond accurately to temperature changes.

This OEM part is also compatible with models from Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore.

This part addresses issues such as:
- Freezer not defrosting
- Refrigerator being too warm
