OEM Carrier Control Board CESO110074 for Model FB5BNF030000AAAA

Keep your fan coil unit running reliably with this genuine OEM Carrier control board, designed specifically for the FB5BNF030000AAAA. The control board governs blower operation, relay timing, safety interlocks, and communication with your thermostat. A failing board often shows up as no airflow, erratic cycling, fault codes, or a system that won't respond to thermostat demands. This factory-spec replacement provides the exact pin layout, firmware, and electrical ratings required by the FB5BNF030000AAAA, avoiding the wiring and compatibility headaches of universal boards. Installation is rated moderate and should be handled by a qualified HVAC technician; expect 30-60 minutes and be sure to photograph and replicate the existing wire harness before swapping. Always shut off power at the breaker before servicing. Orders placed before 3PM CST ship same-day from our warehouse to minimize system downtime.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB5BNF030000AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FB5BNF030000AAAA. 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 FB5BNF030000AAAA?
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?
