OEM Carrier Defrost Control Board HK32EA001 for Model PH13NR024000ACAA

This is the genuine OEM Carrier defrost control board (part number HK32EA001), the factory-specified replacement for the Carrier PH13NR024000ACAA heat pump. The defrost control board monitors outdoor coil conditions and automatically initiates timed defrost cycles to prevent ice accumulation on the evaporator coil. When this board fails, you'll typically see persistent frost or ice buildup on the outdoor unit, the system stuck in continuous defrost mode, or a heat pump that delivers little to no heat on cold days. Cross-reference part numbers include: CEPL130524-01, CEBD430524-06A, 1173636, and 1177927.

  • Specs: Carrier OEM Defrost Timer/Control Board | Part No. HK32EA001 | Compatible defrost timing intervals: 30, 60, and 90 minutes | 24V control circuit | Direct plug-in connector replacement
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket clone. OEM boards are manufactured to exact factory tolerances, ensuring reliable defrost timing and safe reversing valve sequencing. Aftermarket boards may use off-spec timing circuits that cause premature re-icing or compressor stress.
  • Install difficulty: 3/5 — Requires shutting down and locking out the heat pump at the disconnect. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, a smartphone to photograph wiring before disconnection. Note: if upgrading from HK32EA007, set defrost time selection to 60 minutes on the 001 board. Always confirm no frost damage to other components before powering the unit back on.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Carrier PH13NR024000ACAA heat pumps. Also fits select Carrier, Bryant, and Payne heat pump models using the HK32EA001 board — verify your model's data plate and existing part number before ordering. Need help confirming fitment? Our HVAC parts specialists are available to verify compatibility before you buy.

Frequently Asked Questions

Does this Control Board fit my Carrier PH13NR024000ACAA?
Yes. This is the factory-specified OEM control board for the Carrier PH13NR024000ACAA. 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 PH13NR024000ACAA?
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?
