Genuine OEM Carrier Control Board for Fan Coil Model FY5BNF018000AAAA

This genuine OEM Carrier control board is the central circuit board that manages operation of your FY5BNF018000AAAA fan coil unit. It governs blower motor staging, relay sequencing, safety interlocks, and communication between the thermostat and the air handler, ensuring quiet, efficient, and reliable airflow. A failing board often shows up as a blower that won't start, intermittent operation, or no response from the thermostat. Engineered to exact factory specifications, this board is a direct-fit replacement for the FY5BNF018000AAAA, so there is no need to modify wiring harnesses or mounting points. Installation is moderate difficulty and best handled by a qualified HVAC technician; always disconnect power before servicing. Using the correct OEM board protects your system warranty and avoids the compatibility headaches of universal aftermarket boards. Every order placed before 3PM CST ships same-day, so you can get your system back online fast.

Frequently Asked Questions

Does this Control Board fit my Carrier Fan Coil Model FY5BNF018000AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Fan Coil Model FY5BNF018000AAAA. 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 Fan Coil Model FY5BNF018000AAAA?
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.
