OEM Carrier Defrost Control Board HK32EA001 for Model PH12NA01800GAGAA

This is the factory OEM defrost control board for the Carrier PH12NA01800GAGAA heat pump. The defrost control board monitors outdoor coil temperature and ambient conditions, initiating timed defrost cycles to prevent ice buildup on the outdoor coil. When this board fails, your heat pump may stay locked in cooling mode, fail to reverse into heating, short-cycle erratically, or run continuously without ever triggering a defrost cycle — leaving you with a frozen-over outdoor unit and no heat on the coldest days.

  • Specs: OEM Part # HK32EA001 | Board ID: CEPL130524-01 / CEBD430524-06A | 24V control voltage | 5A | Single-phase | Compatible relay: Potter & Brumfield T9AS2D22-24
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact factory tolerances. Generic boards often use lower-rated relays and off-spec timing circuits that can cause premature re-failure or incorrect defrost interval timing, risking compressor damage from sustained ice load.
  • Install difficulty: 3/5 — Requires shutting off power at the disconnect and breaker before opening the control panel. Photograph all wiring harness connections before removal. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone/camera for wiring documentation. Note: discharge any capacitors present before reaching into the control compartment.
  • Warranty: 1-year OEM factory warranty on parts and workmanship. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Direct OEM replacement for the Carrier PH12NA01800GAGAA heat pump. Also fits a broad range of Carrier, Bryant, and Payne heat pump models — verify your unit's data plate part number matches HK32EA001 before ordering. Cross-reference board IDs CEPL130524-01 or CEBD430524-06A confirm compatibility. Need help verifying fitment?

Frequently Asked Questions

Does this Control Board fit my Carrier PH12NA01800GAGAA?
Yes. This is the factory-specified OEM control board for the Carrier PH12NA01800GAGAA. 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 PH12NA01800GAGAA?
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?
