Customer Questions and Answers for Defrost Bimetal by Whirlpool

The Defrost Bimetal is an OEM part for Whirlpool refrigerators. It acts as a safety thermostat that monitors and controls the temperature during the defrost cycle. This component ensures that the defrost heater turns off when the evaporator coil reaches a specific temperature, preventing overheating and potential damage.

Causes of failure may include a malfunction due to wear and tear over time, electrical failure, or damage from moisture and ice.  

Symptoms of a bad Defrost Bimetal include:

• The refrigerator is constantly running without cycling off
• Frost buildup on the evaporator coils, leading to reduced cooling efficiency
• The refrigerator or freezer compartment is too warm
• Unusual fluctuations in refrigerator temperature

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