WP12729123 Whirlpool Defrost Heater Assembly

The Defrost Heater Assembly is a genuine OEM replacement part suitable for Whirlpool refrigerators. This component plays a crucial role in melting the accumulated ice on the evaporator coil, which is a common occurrence during regular refrigerator use. It operates by heating the coil through electrical resistance, ensuring the refrigerator defrosts efficiently at regular intervals.

Whirlpool manufactures this part, and it is also compatible with several other brands including Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and certain Kenmore models. Additionally, Whirlpool produces components for Sears-Kenmore and Ikea appliances.

A malfunctioning defrost heater may stem from various issues such as faulty wiring connections, damaged heating elements, or repeated overheating during defrost cycles.

Signs that may indicate a problem with the defrost heater include:

- Inadequate defrosting of the refrigerator
- Heavy ice formation around the coils
- Difficulty maintaining the desired internal temperatures
- Presence of frost or moisture in compartments outside of the freezer

Identifying these symptoms early can help maintain the efficiency and longevity of your refrigerator.
