W10822278 Replacment

The W10822278 Defrost Timer automates the defrost cycle in frost-free refrigerators. It periodically switches the system from cooling to defrost mode, allowing ice buildup on the evaporator to melt and preventing frost accumulation from affecting performance.

W10822278 Key Features:

Operates at 120 VAC, 50/60 Hz in typical refrigerator control systems

Defrost cycle timing: ~21 minutes of defrost every 8 hours (typical factory program)

Includes mounting hardware and a “flying lead” (wire harness) connection

Can advance manually (by turning dial) for diagnostics or servicing

Supports both continuous and cumulative defrost systems depending on refrigerator model

Fits multiple Whirlpool, Kenmore, Maytag, KitchenAid, Amana, and related refrigerator models that specify W10822278 (or cross-reference part numbers)
