OEM Carrier Fan Coil Control Board for Model FA4CNC036005AAAA

This genuine OEM Carrier control board is the central electronic brain of the FA4CNC036005AAAA fan coil unit, managing blower operation, fan speed staging, and safety interlocks for reliable, efficient airflow. When your air handler stops responding, short-cycles, or the blower fails to start, a failed control board is a common cause, and replacing it restores full system function without guesswork. Built to exact factory specifications, this board ensures correct voltage handling and signal timing that aftermarket substitutes often cannot match. Installation is moderate in difficulty and best handled by an HVAC professional: power down at the breaker, photograph and transfer the wiring harness connections, then mount the new board. Most experienced technicians complete the swap in under an hour. Using the factory part protects your equipment warranty and prevents recurring faults from mismatched logic. We ship same-day on all orders placed before 3PM CST, so your repair stays on schedule. Order the correct OEM Carrier control board for your FA4CNC036005AAAA and get your comfort system back online fast.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4CNC036005AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4CNC036005AAAA. 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 FA4CNC036005AAAA?
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?
