OEM Carrier Defrost Control Board HK32EA001 for Model PH13NR03000GACAA

This is the genuine OEM defrost control board (part number HK32EA001) factory-specified for the Carrier PH13NR03000GACAA 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 heat pump may run continuously in defrost mode, never enter defrost at all, or lock out entirely — leaving you with reduced heating capacity or a fully non-operational system.

  • Specs: OEM Carrier defrost timer board | Part No. HK32EA001 | Also cross-references: CEPL130524-01, CEBD430524-06A, 1173636, 1177927 | Adjustable defrost timing intervals (30 / 60 / 90 min) | 24V control circuit compatible
  • OEM vs Generic: This factory-authorized OEM board meets exact Carrier engineering tolerances. Aftermarket boards often use off-spec timing components that cause premature defrost cycling or extended icing — accelerating compressor wear and reducing system efficiency.
  • Install difficulty: 3/5 — Requires disconnecting 24V low-voltage and high-voltage wiring. Always photograph all wire connections before removal. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Verify defrost sensor (HH18HA279) and defrost thermostat (HH18HA282) before condemning the board.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for the Carrier PH13NR03000GACAA heat pump. Also compatible with select Carrier, Bryant, and Payne heat pump models that specify the HK32EA001 board — verify your unit's data plate and existing board part number before ordering. Our HVAC parts specialists are available to confirm fitment before you buy.

Frequently Asked Questions

Does this Control Board fit my Carrier PH13NR03000GACAA?
Yes. This is the factory-specified OEM control board for the Carrier PH13NR03000GACAA. 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 PH13NR03000GACAA?
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?
