OEM Carrier Control Board CH13NA03700GACAA for Model CH13NA03700GACAA

This OEM Carrier control board is the central circuit board that manages ignition sequencing, blower timing, safety interlocks, and component communication for your Carrier CH13NA03700GACAA condensing unit. When your system fails to start, short-cycles, or throws diagnostic fault codes, a failed control board is a common cause. This genuine Carrier replacement is built to factory specifications for an exact electrical and mechanical match, ensuring reliable operation and protecting connected components from voltage faults. Designed specifically for the CH13NA03700GACAA, it drops into the existing mounting location with the same wiring harness connections. Installation is moderate difficulty and best handled by a qualified HVAC technician, since it involves line-voltage and low-voltage wiring; most installs take under an hour with the unit powered down. Always photograph wiring before disconnecting. Using a genuine OEM board preserves your equipment warranty and avoids the compatibility headaches of universal aftermarket boards. In stock and ships same-day when ordered before 3PM CST, so you can get your system back online fast.

Frequently Asked Questions

Does this Control Board fit my Carrier Model CH13NA03700GACAA?
Yes. This is the factory-specified OEM control board for the Carrier Model CH13NA03700GACAA. 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 Model CH13NA03700GACAA?
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?
