OEM Carrier Control Board CESO110074 for Model FC4BNB060020AAAA

This genuine Carrier control board (CESO110074) is the main circuit board that controls blower operation, fan timing, and safety interlocks in your FC4BNB060020AAAA fan coil unit. It reads thermostat demands, sequences relays, and drives the blower motor to provide smooth, dependable heating and cooling cycles. As a true OEM part, it is manufactured to Carrier's exact factory specifications for a precise fit in the FC4BNB060020AAAA, eliminating the wiring and compatibility headaches of generic replacement boards. Signs of a failed board include a blower that won't start, intermittent or erratic operation, or no response to thermostat calls. Installation is moderate in difficulty and best performed by an HVAC technician: disconnect power, photograph the existing wiring, and transfer each connector to the new board carefully. Most jobs are finished in under an hour. Replacing the board restores full system control and helps protect your equipment from further damage. Backed by genuine Carrier engineering, it brings your unit back to peak performance. Order before 3PM CST for same-day shipping. In stock and ready to ship today.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FC4BNB060020AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FC4BNB060020AAAA. 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 FC4BNB060020AAAA?
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?
