OEM Carrier Defrost Control Board HK32EA007 for Model PH13NR03600GAJAA

This is the genuine OEM Carrier defrost control board (part number HK32EA007), the factory-specified replacement for the Carrier PH13NR03600GAJAA heat pump. The defrost control board governs the automatic defrost cycle — monitoring outdoor coil temperature and initiating timed defrost sequences to melt frost and ice accumulation off the evaporator coil. When this board fails, you'll typically see symptoms such as the outdoor unit icing over completely, the heat pump running in permanent heating or cooling mode without switching, erratic defrost timing, or a system that fails to deliver adequate heat output during cold weather.

  • Part Specs: OEM Part Number HK32EA007 | Genuine Carrier factory board | Also cross-references: HK32EA001, 1173636, 1177927 | Direct plug-and-play replacement with original connectors
  • OEM vs Generic: The OEM HK32EA007 board is factory-programmed with Carrier's exact defrost timing algorithms and temperature thresholds. Aftermarket boards may use generic defrost logic that causes under- or over-defrosting, shortening compressor life and reducing heating efficiency in cold climates.
  • Install Difficulty: 3/5 — Requires disconnecting 24V and line-voltage wiring; always shut off power at the disconnect before beginning. Photograph all wiring connections before removal. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, needle-nose pliers. A multimeter is recommended to verify 24V control circuit integrity post-install. Most experienced DIYers can complete in 30–60 minutes.
  • Warranty: 1-year OEM manufacturer's warranty. In-stock units ship same business day from our warehouse.

Compatibility: Direct OEM replacement for the Carrier PH13NR03600GAJAA heat pump split system. Cross-reference part numbers HK32EA001 and legacy board IDs 1173636 and 1177927 also apply. Always verify your existing board's part number on the label before ordering. Have questions about fitment? Our HVAC parts specialists verify compatibility before you buy — call or chat today.

Frequently Asked Questions

Does this Control Board fit my Carrier PH13NR03600GAJAA?
Yes. This is the factory-specified OEM control board for the Carrier PH13NR03600GAJAA. 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 PH13NR03600GAJAA?
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?
