Whirlpool Defrost Control Board 4388931 OEM Part

Defrost Control Board for Refrigerators

This component is critical when a freezer does not defrost properly or a refrigerator experiences inadequate cooling.

The Defrost Control Board, manufactured by Whirlpool, fits a range of brands such as Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. Whirlpool also supplies components for Sears-Kenmore and Ikea refrigerators. This board, as an Original Equipment Manufacturer (OEM) part, integrates into the control system of Whirlpool refrigerators. It regulates the defrost cycle by managing the heating elements responsible for melting frost. This function ensures that the refrigerator operates effectively, preventing excessive frost accumulation on the evaporator coils.

You may need to replace the Defrost Control Board due to factors like electrical surges, normal wear and tear, or production flaws.

Signs that the Defrost Control Board may be failing include:

- Build-up of frost or ice in the freezer
- Difficulty maintaining the set temperature in the refrigerator or freezer
- Continuous refrigerator operation without entering the defrost cycle
- Signs of overheating or scorch marks on the board

This OEM board is compatible with models from Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore as well.
