W10366605 Replacement

The W10366605 Defrost Control Board (also called the adaptive defrost control or ADC) manages the automatic defrost cycle of frost-free refrigerators. It evaluates usage patterns and temperature conditions to initiate and terminate defrost events, helping prevent frost buildup while maintaining cooling efficiency.

Adaptive (smart) defrost logic rather than fixed-interval defrost timing

Four terminal outputs for heater, compressor, evaporator fan, and supply line

Operates at 120 VAC input, matching typical refrigerator control power

Includes mounting holes and PCB form factor matched to factory assemblies

Monitors run time and temperatures to calculate optimal defrost periods

Compatible with certain Whirlpool, Kenmore, KitchenAid, and related refrigerator models listing W10366605 (or cross-references WPW10366605, AP6020483) as the defrost control component
