The Heater is an OEM part for Whirlpool refrigerators. This component is responsible for preventing frost build-up on the evaporator coils by periodically heating them to melt any accumulated ice. This defrost process is essential for maintaining efficient cooling and proper airflow within the refrigerator.
Over time, the heater can fail due to electrical issues, wear and tear, or burnout from frequent cycling. When the heater is defective, it can lead to excessive frost build-up, which impairs the refrigerator's cooling performance.
Symptoms of a bad heater include:
- Frost or ice build-up on the evaporator coils
- Refrigerator or freezer not cooling properly
- Water leakage inside the refrigerator
- Long defrost cycles or constant running of the refrigerator
This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
