OEM Carrier Defrost Control Board HK32EA001 for Model PH10PA060000ACAA

This is the factory OEM defrost control board (part number HK32EA001) for the Carrier PH10PA060000ACAA heat pump. The defrost control board monitors outdoor coil temperature and time intervals, initiating and terminating defrost cycles to prevent ice buildup on the outdoor unit. When this board fails, common symptoms include a continuously iced outdoor coil, a heat pump that runs in defrost mode non-stop, failure to switch between heating and cooling modes, or a unit that locks out entirely after repeated failed defrost attempts.

• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP), manufactured to exact factory specifications. Generic aftermarket boards may use off-tolerance relay components (such as the Potter & Brumfield T9AS2D22-24 relay) that can cause premature failure and void remaining equipment warranties.
• Install difficulty: 3/5 — Shut off power at the disconnect and breaker before opening the control panel. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, phone or camera to photograph wiring harness connections before removal. Label each connector. The board mounts on a DIN rail or screw standoffs; transfer one connector at a time to avoid miswiring.
