OEM Carrier Control Board HK61EA005 for Model FB4BNF042015AAAA

The OEM Carrier control board (HK61EA005) is the electronic brain of your FB4BNF042015AAAA fan coil unit, managing blower start-up, fan speed, cycle timing, and built-in safety functions during heating and cooling operation. A failing board typically causes a blower that won't run, no response to thermostat calls, intermittent cycling, or a completely unresponsive unit. This genuine factory replacement is matched to the exact specifications of the FB4BNF042015AAAA so the thermostat, blower motor, and electric heat communicate reliably for steady, even comfort. Installation is moderate difficulty and best performed by a licensed HVAC technician: disconnect power at the breaker, photograph and label every wiring harness, move the connectors to the corresponding terminals on the new board, and secure it. Confirm your current board's part number before ordering to ensure an exact match. An OEM board avoids the reliability and compatibility problems common with universal replacements. In stock and shipping same-day on orders placed before 3PM CST, so you can get your air handler back up and running quickly with trusted Carrier quality.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB4BNF042015AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FB4BNF042015AAAA. 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 FB4BNF042015AAAA?
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?
