OEM Carrier Control Board Replacement for Model FC4BNF030015AAAA

This genuine OEM Carrier control board is the brain of your FC4BNF030015AAAA fan coil unit, governing blower motor staging, relay activation, and the safety interlocks that keep your system operating correctly. Symptoms of a failing board include an air handler that won't power up, a blower that ignores thermostat demands, or erratic short-cycling. Manufactured to Carrier's exact specifications for the FC4BNF030015AAAA, this board guarantees correct voltage management and signal timing — reliability you can't count on from universal aftermarket alternatives. Installation is a moderate task suited to an HVAC professional: kill power at the breaker, photograph the existing wiring, transfer each connector to the matching terminal, and mount the board on the original standoffs. A seasoned tech typically wraps up in 30 to 45 minutes. Each board arrives tested and install-ready. Submit your order before 3PM CST for same-day shipping so your home returns to comfortable temperatures without delay. Trust a control board engineered specifically for your Carrier equipment to deliver dependable, safe performance.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FC4BNF030015AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FC4BNF030015AAAA. 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 FC4BNF030015AAAA?
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?
