OEM Carrier Defrost Control Board HK32EA001 for Model PH12NA06000GABAA

This genuine OEM defrost control board (part number HK32EA001) is the factory-authorized replacement for the Carrier PH12NA06000GABAA heat pump. The defrost control board monitors outdoor coil conditions and governs the timing and duration of each defrost cycle — reversing refrigerant flow to melt accumulated ice from the outdoor coil so the unit can maintain efficient heat transfer. When this board fails, the heat pump will typically remain locked in cooling mode, allow excessive ice buildup on the outdoor coil, or fail to complete the defrost cycle entirely, leading to reduced capacity, high energy consumption, and potential compressor damage.

• Specs: 24V control circuit | Board model CEPL130524-01 | Compatible relay: Potter & Brumfield T9AS2D22-24 | Factory-matched timing intervals | Single-phase, 5A rated
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP). OEM boards use factory-calibrated defrost timing logic that protects compressor life. Aftermarket boards often use generic timer intervals that can cause premature cycling or inadequate defrost, shortening system lifespan.
• Install difficulty: 3/5 — Disconnect power at the breaker and wait 5 minutes before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone camera to photograph wiring before disconnection. Match all harness connectors carefully — incorrect wiring can damage the new board.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.
