OEM Carrier Control Board HK42FZ034 for Model FA4ANC036010AFAA

This OEM Carrier control board manages ignition sequencing, blower timing, and safety lockout for your Carrier FA4ANC036010AFAA fan coil air handler. As the brain of the system, it monitors thermostat calls, sensor inputs, and motor operation to ensure safe, efficient heating and cooling cycles. A faulty board often causes no-start conditions, intermittent operation, or blower failures, so a genuine Carrier replacement restores reliable performance and protects connected components. Engineered to exact factory specifications, this board guarantees correct pin layout, voltage handling, and firmware compatibility with the FA4ANC036010AFAA — eliminating the guesswork of universal aftermarket boards. Installation is moderate difficulty and best handled by an HVAC technician: power down the unit, photograph wiring, transfer connectors one at a time, and verify operation. Most installs take under an hour with basic tools. We ship same-day on all orders placed before 3PM CST, so you can get your system back online fast. Order with confidence knowing you are receiving authentic OEM Carrier quality backed by precise model compatibility and dependable, fast fulfillment.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4ANC036010AFAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4ANC036010AFAA. 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 FA4ANC036010AFAA?
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?
