The OEM defrost control board (part number 1069364) is the electronic controller that runs the defrost cycle on your ICP YJ030GA1 heat pump. It tracks outdoor coil temperature and compressor run time, then commands the reversing valve and supplemental heat to melt frost off the outdoor coil during heating operation. When this board fails, the outdoor unit can ice over, short-cycle, refuse to change between heating and cooling, or stop running altogether. A bad defrost board is among the most common reasons a heat pump freezes solid or loses heat in winter. This genuine OEM replacement is built to the exact defrost timing and relay logic of the original board.
