OEM Carrier Control Board Replacement for Model FA4CNC018005AAAA

Bring your system back online with this genuine OEM Carrier control board, built specifically for the FA4CNC018005AAAA fan coil/condensing unit. The control board is the brain of your equipment, managing blower operation, safety lockouts, fan timing, and communication between thermostat and components. Symptoms of a failing board include no response from the unit, intermittent operation, blown fuses, or error codes, all of which a new factory board resolves. Manufactured to exact Carrier specifications, this board matches the original connector layout and firmware logic of the FA4CNC018005AAAA, ensuring proper plug-and-play replacement. Installation is moderate difficulty and best handled by a qualified HVAC technician; expect 30-45 minutes to label wiring, swap the board, and confirm operation with power disconnected. Choosing the OEM board over a generic substitute protects your warranty and avoids compatibility headaches. Orders placed before 3PM CST ship same-day from our US warehouse so your downtime stays minimal. Buy with confidence from NationalHVACParts.com.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4CNC018005AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4CNC018005AAAA. 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 FA4CNC018005AAAA?
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?
