OEM Carrier Defrost Control Board HK32EA007 for Model CH13NA06000GACBA

This is the factory OEM defrost control board (part number HK32EA007) for the Carrier CH13NA06000GACBA heat pump condenser. The defrost control board manages the automatic defrost cycle, monitoring outdoor coil temperature and initiating timed defrost sequences to prevent ice buildup on the coil. When this board fails, common symptoms include a frozen outdoor coil, the unit running continuously in heating mode without defrosting, error codes related to defrost faults, or the system locking out entirely. Replacing the defrost board with the correct OEM part restores precise cycle timing and protects your compressor from the damage caused by sustained ice accumulation.
