OEM Carrier Control Board FK4BNF003010AAAA for Model FK4BNF003010AAAA

This OEM Carrier control board is the genuine replacement for the FK4BNF003010AAAA fan coil unit, serving as the electronic brain that governs blower operation, fan speed staging, safety circuits, and thermostat signals. A failed board typically presents as a non-running blower, intermittent operation, or a completely dead system—this factory part restores accurate, reliable control. Manufactured to Carrier's exact specifications for the FK4BNF003010AAAA, it delivers a precise functional and physical match, so you avoid the compatibility and reliability problems associated with universal boards. Installation difficulty is moderate and recommended for a qualified HVAC technician: disconnect power, label and transfer the wire harnesses and connectors, mount the replacement board, and confirm operation. Most jobs finish in 30 to 60 minutes with standard hand tools. Each board ships brand-new and never refurbished, backed by Carrier's reputation for durability. We stock this part and ship same-day on all orders placed before 3PM CST. Order from NationalHVACParts.com for a guaranteed OEM fit and long-lasting, worry-free performance.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FK4BNF003010AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FK4BNF003010AAAA. 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 FK4BNF003010AAAA?
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?
