Overview
This OEM defrost control board (part number 1069364) manages the defrost cycle on ICP/Tempstar/Heil heat pumps such as the YG024GB1. The board monitors the defrost sensor and run time, then commands the reversing valve, auxiliary heat, and outdoor fan to clear frost from the outdoor coil during cold-weather operation. When it fails, the heat pump can ice over and lose heating capacity, run constant or no defrost cycles, or fail to energize backup heat. Symptoms include a frosted or iced outdoor coil, no defrost cycle, the unit stuck in defrost, or no response from the reversing valve and fan during the cycle.
