OEM Carrier Control Board Replacement for Model FA4ANC018005AGAA

This authentic OEM Carrier control board serves as the electronic command center of your air handler, coordinating blower speed, fan timing, safety controls, and signals from the thermostat and outdoor unit. A failed board can cause no airflow, a blower that runs constantly, erratic cycling, or a system that won't power up at all. Designed as a direct-fit replacement for the Carrier FA4ANC018005AGAA fan coil, this board restores accurate, dependable, and safe operation to your cooling and heating system. Manufactured to precise factory specifications, it delivers correct relay timing, voltage management, and built-in fault protection that off-brand boards often fail to provide. Installation is an advanced job best handled by a licensed HVAC technician — high-voltage connections, multiple plugs, and dip-switch configurations must be matched exactly, with power disconnected before servicing. A professional can usually complete the replacement in under an hour. Using the exact OEM board avoids wiring errors and recurring faults. This item is in stock and ships same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4ANC018005AGAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4ANC018005AGAA. 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 FA4ANC018005AGAA?
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?
