OEM Carrier Defrost Control Board HK32EA007 for Model PH14PB03600GBAAB

This is the genuine OEM Carrier defrost control board (part number HK32EA007), factory-specified for the Carrier PH14PB03600GBAAB heat pump. The defrost control board manages the timing and execution of the defrost cycle, commanding the reversing valve and defrost termination based on temperature and time inputs. When this board fails, symptoms typically include continuous icing of the outdoor coil, failure to switch between heating and cooling modes, short-cycling, or a complete heat pump lockout with no error recovery — all signs the defrost logic has stopped functioning correctly.

  • Specs: OEM Part # HK32EA007 | Also supersedes / cross-references: HK32EA001, 1173636, 1177927 | Factory-matched control logic for Carrier heat pump defrost sequencing
  • OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket clone. OEM boards carry factory-programmed defrost timing parameters tuned specifically for Carrier heat pump models, reducing the risk of nuisance lockouts or premature compressor cycling that can occur with lower-tolerance aftermarket alternatives.
  • Install difficulty: 3/5 — Requires disconnecting low-voltage control wiring at multiple terminals and removing the board from its mounting bracket. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers, phone or camera to photograph wiring before removal. Always disconnect power at the disconnect box before beginning. If fault codes are present, record them before replacing the board.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse when ordered by cutoff time.

Compatibility: Designed for the Carrier PH14PB03600GBAAB heat pump. Cross-references include HK32EA001, 1173636, and 1177927. Verify your existing board's part number against your unit's data plate before ordering — if you have any doubts, our HVAC parts specialists are available to confirm fitment before you buy. Order today and get same-day shipping on in-stock inventory.

Frequently Asked Questions

Does this Control Board fit my Carrier PH14PB03600GBAAB?
Yes. This is the factory-specified OEM control board for the Carrier PH14PB03600GBAAB. 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 PH14PB03600GBAAB?
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?
