The primary function of the Defrost Heater is to prevent the accumulation of frost and ice on the evaporator coils of the refrigerator. It operates by heating periodically to melt the frost, thereby ensuring unobstructed airflow through the coils and maintaining optimal cooling efficiency.

Potential causes of a malfunctioning Defrost Heater include electrical problems such as a blown fuse or defective wiring, natural wear and tear, or issues within the heating element itself.

Signs that may indicate a failing Defrost Heater are:
- Frost or ice accumulation on the evaporator coils
- An increase in the temperature of the refrigerator or freezer compartments
- The refrigerator operating more frequently or for extended periods
- Overall diminished cooling efficiency within the refrigerator

This replacement part is designed to fit not only Whirlpool refrigerators but also those from Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and some Kenmore models.
