OEM Carrier Defrost Control Board HK32EA007 for Model CH13NA04200GACAA

This is the factory OEM defrost control board (part number HK32EA007) designed as a direct replacement for the Carrier CH13NA04200GACAA heat pump system. The defrost control board manages the automatic defrost cycle, monitoring outdoor coil temperatures and initiating timed or sensor-triggered defrost sequences to prevent ice buildup on the outdoor unit. When this board fails, common symptoms include the outdoor coil freezing solid, the system failing to enter or exit defrost mode, erratic heating performance, or a complete loss of heat pump operation. Left unaddressed, a faulty defrost board can cause compressor damage due to prolonged icing.

  • Specs: OEM Part Number HK32EA007 | Factory-matched defrost timing and temperature thresholds | 24V control circuit compatible | Direct plug-and-play wiring harness fitment for CH13NA04200GACAA
  • OEM vs Generic: This is the genuine Carrier OEM board — not an aftermarket substitute. OEM boards maintain factory-programmed defrost intervals and sensor calibration. Generic boards frequently use mismatched timing logic that leads to premature compressor cycling or insufficient defrost, voiding extended equipment warranties.
  • Install Difficulty: 3/5 — Requires disconnecting power at the breaker and discharging any residual voltage before opening the control panel. Tools needed: Phillips and flathead screwdrivers, a nut driver set, needle-nose pliers, and a multimeter to verify 24V circuit integrity post-installation. Photograph all wiring connections before removal. Consult a licensed HVAC technician if unfamiliar with heat pump control wiring.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier CH13NA04200GACAA heat pump condenser. Always cross-reference the OEM part number HK32EA007 against your unit's wiring diagram and data plate before ordering. Our HVAC parts specialists are available to confirm fitment — order with confidence and get your system back to peak efficiency fast.

Frequently Asked Questions

Does this Control Board fit my Carrier CH13NA04200GACAA?
Yes. This is the factory-specified OEM control board for the Carrier CH13NA04200GACAA. 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 CH13NA04200GACAA?
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?
