Customer Questions and Answers for Defrost Heater by Whirlpool

The Defrost Heater is an OEM part for Whirlpool refrigerators. This part prevents the build-up of frost and ice on the evaporator coils. By periodically heating up to melt away frost, this component ensures that air can flow freely through the coils, maintaining the refrigerator's efficient cooling performance.

Causes of a bad defrost heater can include electrical issues, such as a blown fuse or faulty wiring, wear and tear over time, or a malfunction within the heating element itself.

Symptoms of a bad Defrost Heater include:

• Frost or ice buildup on the evaporator coils
• The refrigerator or freezer compartment warming up
• The refrigerator cycling on more frequently or for longer durations
• Poor cooling performance throughout the refrigerator

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