OEM Carrier Control Board CESO110074 for Model FA4BNC036005AAAA

This genuine OEM Carrier control board (CESO110074) is the central electronic control of your FA4BNC036005AAAA fan coil unit, governing blower operation, fan timing, safety circuits, and thermostat communication. When the board fails, you may see erratic blower cycling, no airflow, repeatedly blown fuses, or a system that won't respond at all, and an exact OEM replacement is the dependable solution. Manufactured to precise Carrier specifications, this board matches the original's relay configuration, terminal layout, and control logic for genuine plug-and-play fit. Installation is a moderate-to-advanced job: disconnect power, carefully label and photograph each wiring harness, remove the old board, mount the replacement, and reconnect every connector to its matching terminal. Because of the wiring complexity, we recommend a licensed HVAC technician unless you're experienced with control wiring. Each board is authentic OEM and backed by our quality guarantee for long-term reliability. In stock and ships same-day when you order before 3PM CST, so you can restore proper control and airflow to your Carrier air handler without delay.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4BNC036005AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4BNC036005AAAA. 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 FA4BNC036005AAAA?
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?
