This genuine OEM defrost control board (part number 34332101) manages the defrost cycle on the ICP/Heil/Tempstar YE060F heat pump. The board monitors the defrost thermostat and coil temperature, then initiates and terminates defrost based on its timer interval to clear frost and ice from the outdoor coil during heating operation. It coordinates the compressor, the reversing valve, and the outdoor fan, and energizes auxiliary heat as needed during the cycle. When the defrost board fails, the outdoor coil can ice over and choke airflow, the system loses heating capacity, the reversing valve may not switch, or the unit may get stuck in defrost. Because it sits in a harsh outdoor environment exposed to moisture, temperature swings, and voltage surges, the defrost board is a common service replacement on aging heat pumps.
