OEM Carrier Defrost Control Board HK32EA007 for Model CH14NB04200GAAAA

This is the factory OEM defrost control board (part number HK32EA007) for the Carrier CH14NB04200GAAAA heat pump condenser. The defrost control board monitors outdoor coil temperature and ambient conditions, initiating timed or demand-based defrost cycles to prevent ice buildup on the outdoor coil. When this board fails, symptoms typically include the outdoor coil freezing solid, the system failing to enter defrost mode, erratic heating performance, or the unit locking out entirely during cold-weather operation — leaving your home without heat when you need it most.
