OEM Carrier Control Board HK61EA005 for Model FB4BNF030010AAAA

Restore full control of your Carrier FB4BNF030010AAAA fan coil with this genuine OEM control board. The board is the brain of your air handler, managing blower operation, fan timing, and the safety and sequencing logic that keeps your heating and cooling system running correctly. When it fails you may see a blower that won't start, erratic fan behavior, or no response from the thermostat. This factory-specified replacement matches the original connector layout and mounting points, so harness plugs and standoffs line up exactly — no splicing or rewiring needed. Installation is a moderate job best suited to experienced DIYers or technicians; with the unit de-energized, most swaps take 30 to 45 minutes using basic hand tools. Installing the correct OEM board ensures proper voltage handling and compatibility with your existing motor and transformer, avoiding the mismatch problems that come with universal aftermarket boards. Orders placed before 3PM CST ship same-day from our warehouse. Trust genuine Carrier parts for dependable, long-term performance.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB4BNF030010AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FB4BNF030010AAAA. 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 FB4BNF030010AAAA?
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?
