Overview
This genuine OEM defrost control board (part 1069364) is the brain of the defrost cycle on the ICP YL030GA1 heat pump. It monitors the defrost thermostat and run time, initiates and terminates defrost, energizes the reversing valve, and coordinates the auxiliary heat and fan during the cycle. When this board fails, the outdoor coil ices over and heating capacity collapses, or the unit defrosts constantly and wastes energy. Boards fail from power surges, corrosion, and failed relays.
