OEM Carrier Control Board HK61EA005 for Model FA4BNF036008AAAA

This genuine OEM Carrier control board manages the core electronics of your FA4BNF036008AAAA air handler, governing blower activation, fan timing, safety logic, and thermostat communication. A failed board can cause a dead blower, random fan cycling, blown low-voltage fuses, or a totally unresponsive unit. A factory-matched replacement restores accurate control sequencing and shields your other components from damage caused by faulty timing. Engineered to exact Carrier specifications for the FA4BNF036008AAAA, this board delivers correct relay operation, voltage handling, and connector compatibility for a precise fit. Because installation involves several line- and low-voltage connections, it is a moderate-to-advanced repair best handled by a licensed HVAC technician—about 45 to 60 minutes. Before removing the old board, photograph and label each wire to ensure an exact, error-free transfer, and always disconnect power first. Order before 3PM CST and your control board ships the same business day to keep downtime to a minimum. Genuine Carrier components deliver the reliability and longevity your system depends on.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4BNF036008AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4BNF036008AAAA. 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 FA4BNF036008AAAA?
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?
