Description
The Defrost Bimetal is an OEM part for Whirlpool refrigerators. This crucial component functions as a safety thermostat in the freezer's defrost system. It is designed to monitor and control the temperature of the evaporator coils during the defrost cycle, preventing them from overheating. By cutting off the defrost heater when the coils reach a certain temperature, the bimetal helps maintain optimal functioning and efficiency of the refrigerator’s defrost system.
Symptoms of a failing defrost bimetal include:
- Build-up of frost on the evaporator coils that does not melt during defrost cycles
- Refrigerator or freezer section getting too warm
- Continuous running of the refrigerator compressor
Causes of bimetal malfunction typically include corrosion, continuous exposure to extreme temperatures, and general wear over time, which can prevent it from responding accurately to temperature changes.
This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
This part fixes the following symptoms
- Freezer not defrosting
- Fridge too warm
