OEM Carrier Control Board CESO110074 for Model FA4ANF048000AGAA

This OEM Carrier control board (CESO110074) is the electronic core of your Carrier FA4ANF048000AGAA fan coil, governing blower timing, safety interlocks, and communication with the thermostat. A failing board can leave you with a non-responsive blower, erratic cycling, blown fuses, or a system that simply won't start. Because it is a genuine Carrier part, this board matches the FA4ANF048000AGAA exactly, delivering the correct relay logic and connector layout that aftermarket boards routinely get wrong. Installing the proper OEM board shields your motors and electronics from faults that mismatched controls can cause. This repair is moderately difficult and should be handled by a licensed HVAC technician: shut off power, photograph the existing wiring, transfer the harness connector by connector, and double-check low-voltage terminations before re-energizing. The job typically runs 30-45 minutes. Restore precise, reliable control to your air handler with the exact component your system was built around. Order before 3PM CST and this Carrier control board ships same-day so your repair stays on track.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4ANF048000AGAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4ANF048000AGAA. 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 FA4ANF048000AGAA?
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?
