OEM Carrier Defrost Control Board HK32EA007 for Model CH13NA03600GACBA

This is the factory OEM defrost control board (part number HK32EA007) for the Carrier CH13NA03600GACBA heat pump condenser. The defrost control board manages the automatic defrost cycle, monitoring outdoor coil temperature and run-time intervals to prevent ice buildup on the refrigerant coil. When this board fails, you may notice continuous frost or ice accumulation on the outdoor unit, a heat pump stuck in defrost mode, reduced heating efficiency, or a system that locks out entirely and refuses to run. Replacing the defrost control board with the exact OEM part restores factory-programmed defrost timing and temperature thresholds — critical for maintaining system efficiency and preventing compressor damage in cold-weather operation.
