This OEM defrost control board (part number 34332101) is the brains of the defrost cycle on your ICP Tempstar Heil YE060H heat pump. The board monitors outdoor coil temperature and accumulated run time, then commands the reversing valve and outdoor fan to clear frost and ice from the outdoor coil during heating operation. When a defrost control board fails, the heat pump either skips defrost entirely — letting the outdoor coil ice over and choke airflow — or it locks into a continuous defrost loop that blows cold air and spikes your energy bills. A correctly functioning 24V defrost board keeps heating efficient and protects the compressor from liquid slugging.
