Overview
This genuine OEM defrost control board (OEM #34332100) manages the defrost cycle on the ICP / Tempstar / Heil YC060F heat pump. The board monitors coil temperature and accumulated run time, then initiates a timed defrost to clear frost from the outdoor coil — reversing the valve, stopping the outdoor fan, and energizing auxiliary heat as needed. A failed board is a common cause of an iced-over outdoor unit, poor heating performance, or a heat pump that never defrosts. Symptoms include heavy frost buildup, no defrost cycle, the reversing valve or fan not responding, and erratic staging.
