OEM Carrier Defrost Control Board HK32EA001 for Model PH3ANA018000BAAA

This is the factory OEM defrost control board for the Carrier PH3ANA018000BAAA heat pump. The defrost control board manages the automatic defrost cycle, receiving signals from defrost sensors and commanding the reversing valve and outdoor fan to temporarily shift the unit into cooling mode to melt frost buildup on the outdoor coil. When this board fails, your heat pump may run continuously in cooling mode, refuse to defrost, or cycle erratically — leaving your home without adequate heat during cold weather. Board cross-references include CEPL130524-01 and CEBD430524-06A.

  • Specs: 24V control voltage | 5A amperage | Single-phase | OEM part number HK32EA001 | Factory Authorized Parts (FAP) replacement
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part — engineered to exact tolerance for the PH3ANA018000BAAA platform. Generic boards may lack proper defrost timing calibration, risking compressor damage from uncontrolled ice buildup.
  • Install difficulty: 3/5 — Disconnect power at the breaker before servicing. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, phone/camera for wiring photos. Photograph all connector positions before removal. The board mounts in the outdoor unit's control compartment and all connectors are keyed for correct reinstallation.
  • Warranty: 1-year OEM factory warranty on this Factory Authorized Part. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH3ANA018000BAAA heat pump. Also fits select Carrier, Bryant, and Payne heat pump models including 38YCG060, 38YCG036, and 538BNR024000BAAA series. Always verify your OEM part number on your unit's data plate or existing board before ordering. Our parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Control Board fit my Carrier PH3ANA018000BAAA?
Yes. This is the factory-specified OEM control board for the Carrier PH3ANA018000BAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier PH3ANA018000BAAA?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. 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?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. 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.
How fast does National HVAC Parts ship?
