OEM Carrier Control Board CESO110057 for Model FB4ANF018008AFAA

This genuine OEM Carrier control board (part CESO110057) directs blower timing, relay operation, and safety interlocks within your Carrier FB4ANF018008AFAA fan coil air handler. When this board goes bad, you may notice the blower not running, fan cycling at random, or the system failing to respond to the thermostat. Replacing it with the factory-engineered board restores correct sequencing and fault protection so your equipment behaves normally. Built to Carrier's exact specifications, it matches the original connector positions and mounting holes for a clean direct-fit swap. Installation is a moderate job for confident DIYers and technicians: shut off power, label and transfer every harness, mount the new board, and test operation. Most installs take 30 to 45 minutes. Choosing OEM avoids the relay-rating and firmware mismatches common to aftermarket boards, protecting the rest of your air handler. We keep this part in stock and ship same-day on orders placed before 3PM CST so your repair does not wait. Order today for an authentic Carrier replacement matched to your exact model.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB4ANF018008AFAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FB4ANF018008AFAA. 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 FB4ANF018008AFAA?
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?
