OEM Carrier Defrost Control Board HK32EA001 for Model PH15NA06000GBAAA

This is the factory OEM defrost control board (part number HK32EA001) for the Carrier PH15NA06000GBAAA heat pump. The defrost control board governs the timed defrost cycle that periodically reverses the refrigerant flow to melt frost accumulation off the outdoor coil. When this board fails, you'll typically see continuous frost or ice buildup on the outdoor unit, the system stuck in heating or cooling mode, the reversing valve failing to switch correctly, or the unit short-cycling without completing a defrost event. Left unaddressed, a failed defrost board accelerates compressor damage and dramatically reduces efficiency.

  • OEM Part Number: HK32EA001 | Cross-references: CEPL130524-01, CEBD430524-06A | Voltage: 24V | Phase: Single-phase | Factory-authorized Carrier replacement part
  • OEM vs Generic: This is a genuine Carrier factory-authorized board with exact firmware, relay ratings, and terminal layout. Aftermarket boards may use off-spec relays or imprecise defrost timing logic, risking compressor flood-back or inadequate deicing — especially critical in heat pump applications.
  • Install Difficulty: 3/5 — Requires disconnecting 24V control wiring harness and 5A board connections. Tools needed: 1/4" nut driver, needle-nose pliers, phone/camera for wiring photos, multimeter. Always shut off power at both the indoor air handler disconnect and the outdoor unit disconnect before servicing. Verify the reversing valve switching function after install. Licensed HVAC technician recommended.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our climate-controlled warehouse when ordered before 3PM local time.

Compatibility: Designed for the Carrier PH15NA06000GBAAA heat pump split system. Verify your existing board's part number and cross-reference numbers on the board label before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions. Order now and get same-day shipping straight to your door.

Frequently Asked Questions

Does this Control Board fit my Carrier PH15NA06000GBAAA?
Yes. This is the factory-specified OEM control board for the Carrier PH15NA06000GBAAA. 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 PH15NA06000GBAAA?
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?
