OEM Carrier Control Board CESO110074 for Model FB4ANB070010ABAA

This genuine Carrier control board is the electronic brain of your FB4ANB070010ABAA fan coil, managing blower operation, sequencing, fan timing, and communication between the thermostat and the system's components. A failing control board can cause no-heat or no-cool conditions, a blower that won't start or won't shut off, erratic cycling, or unresponsive thermostat commands. This OEM replacement is engineered to match the exact firmware, relays, and connector layout specified for the FB4ANB070010ABAA, delivering precise, factory-grade control and a true plug-in fit. Installation is best handled by an experienced HVAC technician and typically takes 30-45 minutes; always disconnect power first and photograph wiring before removing the old board to ensure correct transfer of each connection. Restore full, reliable operation and protect connected components from voltage faults with the correct OEM board. In stock and ships same-day on orders placed before 3PM CST, so your system downtime stays short. Backed by our exact-fit guarantee for the FB4ANB070010ABAA fan coil.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB4ANB070010ABAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FB4ANB070010ABAA. 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 FB4ANB070010ABAA?
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?
