Overview
This genuine OEM defrost control board (part #34332101) is the brain of the defrost cycle on your ICP Tempstar/Heil YG060GC heat pump. It monitors the outdoor coil temperature and run time, then commands the reversing valve, condenser fan, and auxiliary heat to clear frost and ice from the outdoor coil during cold-weather operation. When this board fails, the heat pump can ice over completely, lose heating capacity, short-cycle, or fail to terminate a defrost cycle. Common failure causes include voltage surges, corrosion, failed relays on the board, and burned traces.
