OEM Carrier Control Board Replacement for Model FA4BNF024000AAAA

This genuine OEM Carrier control board is the precise factory replacement for the FA4BNF024000AAAA fan coil unit. The control board manages blower operation, fan timing, safety interlocks, and the communication between your thermostat and motor, acting as the brain of the entire system. A failed board commonly presents as a unit that won't power on, runs erratically, or ignores thermostat calls, making this part essential to proper operation. Built to Carrier's exact firmware and connector specifications, it is fully matched to the FA4BNF024000AAAA and installs using the original wiring harness and mounting standoffs for a clean plug-in fit. Replacement is moderately involved and should be performed by a licensed HVAC technician, typically taking 45 to 60 minutes including labeling and reconnecting each lead carefully. Always disconnect power before beginning. We keep ordering fast and dependable, and any order placed before 3PM CST ships the same business day from our US warehouse. Select this authentic OEM control board to guarantee correct compatibility, safe operation, and reliable long-term performance.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4BNF024000AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4BNF024000AAAA. 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 FA4BNF024000AAAA?
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?
