Overview
This genuine OEM defrost control board (part number 1069364) is the brain of the ICP/Heil/Tempstar YG024GA1 heat pump's defrost cycle. In heating mode the outdoor coil accumulates frost; the defrost board monitors the coil temperature sensor and accumulated run time, then periodically reverses the system to melt that frost so the heat pump can keep operating efficiently. The board manages the reversing valve, the compressor contactor, the outdoor fan, and the timing intervals that determine when and how long a defrost runs. When this board fails you may see the outdoor coil completely iced over, a heat pump that never defrosts (or defrosts constantly), no auxiliary heat staging, or a system that won't switch between heating and cooling. Because the defrost board controls so many functions, a failure often mimics several other component faults at once.
