Product Description

The Whirlpool W10866120 is an OEM replacement control board designed to restore proper operation to compatible Whirlpool and KitchenAid dishwashers. The control board serves as the central electronic brain of the dishwasher, managing cycle selection, water fill timing, wash motor operation, and drain sequencing. Measuring 10.38 x 7.5 x 3.25 inches and weighing 1 pound, it is a direct-fit replacement that reinstalls into the original mounting location without modification.
