OEM Carrier Defrost Control Board HK32EA001 for Model PH4RNG024000BAAA

This is the genuine OEM Carrier defrost control board (part number HK32EA001), the factory-specified replacement for the Carrier PH4RNG024000BAAA heat pump. The defrost control board monitors outdoor coil conditions and initiates timed defrost cycles to prevent ice buildup on the evaporator coil. When this board fails, the system will typically remain locked in a continuous frost or ice accumulation state, causing severely reduced heating output, frozen coils, or a unit that runs but cannot transfer heat effectively. In some cases, a failed board will also prevent the reversing valve from switching properly between heating and cooling modes.

  • OEM Part Number: HK32EA001 | Also cross-references: CEPL130524-01, CEBD430524-06A, 1173636, 1177927 | Factory Authorized Carrier Replacement Components Division part
  • OEM vs Generic: This genuine OEM board is manufactured to exact Carrier factory tolerances. Generic aftermarket boards frequently use off-spec relays and timing components that misfire defrost cycles, leading to repeat coil icing or compressor overload — always choose OEM for defrost control reliability.
  • Install Difficulty: 3/5 — Disconnect power at the disconnect box before servicing. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, phone/camera (photograph all wiring before disconnecting). The board mounts in the outdoor unit control box. Note defrost timing jumper settings before removing the old board and replicate on the new one.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Designed for the Carrier PH4RNG024000BAAA heat pump. This board is also used across select Carrier, Bryant, and Payne heat pump platforms sharing the same defrost control architecture. Always verify your existing board's part number against HK32EA001 before ordering. Have questions about fitment? Our HVAC parts specialists confirm compatibility before you buy — call or chat today.

Frequently Asked Questions

Does this Control Board fit my Carrier PH4RNG024000BAAA?
Yes. This is the factory-specified OEM control board for the Carrier PH4RNG024000BAAA. 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 PH4RNG024000BAAA?
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?
