OEM Carrier Control Board for Model FK4BNF002015AAAA Fan Coil

This OEM Carrier control board is the electronic command center for your FK4BNF002015AAAA fan coil unit, managing blower speed, safety interlocks, and communication between the thermostat and indoor air handler. A failed board causes no-heat, no-cool, or erratic blower operation, so a genuine Carrier replacement restores reliable, factory-spec performance. Engineered specifically for the FK4BNF002015AAAA, it drops into the existing wiring harness and mounting points without modification, ensuring exact voltage and signal compatibility that generic boards cannot guarantee. Installation is moderate difficulty: a competent DIYer can swap it in 30-45 minutes by photographing connections, powering down at the breaker, and transferring plugs one at a time, though many homeowners prefer an HVAC technician for final verification. Each board is tested to Carrier standards for long service life. Order before 3PM CST and your control board ships same-day, getting your system back online fast. Backed by our HVAC parts expertise, this is the correct, durable fix for your Carrier fan coil's electronic control failures.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FK4BNF002015AAAA Fan Coil?
Yes. This is the factory-specified OEM control board for the Carrier Model FK4BNF002015AAAA Fan Coil. 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 FK4BNF002015AAAA Fan Coil?
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?
