Overview
This is a genuine OEM defrost control board (part number 1069364) for the ICP/Tempstar/Heil YL024GB1 heat pump. The defrost board is the brains of heat-pump operation: it monitors the defrost thermostat and coil temperature, times the defrost cycle, energizes the reversing valve and condenser fan as needed, and clears frost buildup from the outdoor coil during cold-weather heating. When the board fails, the heat pump may run continuously in defrost, never defrost at all (allowing the coil to ice over), fail to switch the reversing valve, or stop responding to the thermostat entirely. A no-heat or iced-up outdoor unit in winter is a classic sign of a failed defrost board.
