OEM Carrier Defrost Control Board HK32EA001 for Model PH10JA01800GADAA

This is the genuine OEM defrost control board (part number HK32EA001) factory-specified for the Carrier PH10JA01800GADAA heat pump. The defrost control board governs the timing and execution of each defrost cycle, receiving signals from the thermostat and outdoor sensors to determine when accumulated ice on the coil must be cleared. A failed board typically manifests as a heat pump stuck in constant defrost, refusing to enter defrost at all, excessive outdoor coil icing in heating mode, or erratic reversing valve behavior — all of which rob your system of efficiency and can lead to compressor damage if left unaddressed.

• Specs: 24V | 5A | Single-phase | Board model CEPL130524-01 (cross-ref: CEBD430524-06A, 151922) | Factory-matched OEM tolerances
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not a third-party clone. OEM boards use exact firmware, relay ratings, and terminal configurations to ensure the defrost cycle runs precisely as engineered. Aftermarket boards may use mismatched relays or timing logic that shortens compressor and reversing valve life.
• Install difficulty: 3/5 — Disconnect power at the breaker before beginning. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, needle-nose pliers, and a smartphone to photograph all wiring harness positions before removal. Label each connector. The board mounts in the outdoor unit control compartment. Allow 5 minutes after power-off for capacitors to discharge.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
