OEM Carrier Control Board HK61EA005 for Model FB4BNF030008AAAA

Bring your Carrier FB4BNF030008AAAA fan coil back to full operation with this genuine OEM control board. As the central logic of the air handler, the board governs blower startup, fan timing, and the safety sequencing that protects your equipment and keeps heating and cooling cycles running correctly. Symptoms of a failing board include a blower that won't run, unpredictable fan operation, or no response to thermostat commands. This factory-specified replacement reproduces the original connector positions and mounting layout, so every harness plug and standoff aligns exactly — no cutting, splicing, or rewiring required. Installation is a moderate task suited to confident DIYers and technicians; with the unit de-energized, most replacements take 30 to 45 minutes using basic hand tools. The correct OEM board guarantees proper voltage handling and seamless compatibility with your existing motor and transformer, avoiding the headaches of universal aftermarket boards. Order before 3PM CST and it ships the same day from our warehouse. Count on genuine Carrier parts for lasting, reliable performance.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB4BNF030008AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FB4BNF030008AAAA. 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 FB4BNF030008AAAA?
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?
