OEM Carrier Control Board Replacement for Model FC4BNB054000AGAA

Bring your Carrier FC4BNB054000AGAA fan coil back to full function with this genuine OEM control board, the central module that governs blower operation, relay timing, safety logic, and thermostat communication. When the board fails you may experience a dead unit, intermittent fan cycling, no heating or cooling output, or flashing diagnostic codes. This factory-built replacement is engineered to Carrier specifications for the FC4BNB054000AGAA so it matches the original wiring harness, connectors, and operating sequence exactly. Installation is a moderate task suited to skilled DIYers and HVAC professionals: cut power to the unit, photograph all plug locations, transfer each connector one at a time to the new board, and remount it in the factory position. Expect roughly 30 to 45 minutes to complete. Selecting the genuine OEM board eliminates the compatibility and reliability problems often seen with aftermarket boards. This part is in stock and ships the same day on all orders placed before 3PM CST.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FC4BNB054000AGAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FC4BNB054000AGAA. 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 FC4BNB054000AGAA?
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?
