OEM Carrier Defrost Control Board HK32EA001 for Model PH10JA01800GAHAA

This OEM defrost control board is the factory-specified replacement for the Carrier PH10JA01800GAHAA heat pump. The defrost control board monitors outdoor coil temperature and manages timed defrost cycles, signaling the reversing valve and auxiliary heat to activate when ice buildup is detected. When this board fails, the outdoor coil ices over completely, the unit locks out on fault, or the system fails to switch between heating and cooling modes — leaving your home without reliable comfort in peak cold weather.

  • Specs: OEM Part # HK32EA001 | Board ID: CEPL130524-01 | Voltage: 24V | Phase: 1-Phase | Amperage: 5A | Dimensions: approx. 6" × 4" | Factory-matched logic and relay configuration
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM boards are programmed with exact defrost timing algorithms and relay ratings for your unit. Aftermarket boards may use mismatched relay specs or imprecise defrost timers, risking compressor damage and premature coil icing.
  • Install difficulty: 3/5 — Turn off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone/camera to photograph existing wiring. Transfer one connector at a time to avoid miswiring. Confirm R, C, O/B, and defrost sensor terminals match before powering up.
  • Warranty: 1-year OEM manufacturer warranty. In stock — ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH10JA01800GAHAA heat pump split system. Cross-references include board IDs CEPL130524-01 and CEBD430524-06A. Verify your existing board part number against HK32EA001 before ordering. Have a fitment question?

How do I replace the control board on my Carrier OEM Carrier Defrost Control Board HK32EA001 — PH10JA01800GAHAA?
Difficulty: Advanced (1–2 hrs)

Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?

The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
