OEM Carrier Control Board CESO110074 for Model FB4ANB042015ABAA

This genuine OEM Carrier control board (CESO110074) is the central controller for your FB4ANB042015ABAA fan coil, coordinating blower operation, ECM motor commands, and safety interlocks for steady, reliable comfort. A failed board commonly causes a no-start condition, erratic blower behavior, or fault codes that shut the system down. Manufactured to exact Carrier specifications, this board installs directly into the FB4ANB042015ABAA with no modifications, restoring correct airflow staging and low-voltage communication. Installation is moderate and best left to an HVAC technician: cut power, photograph all wiring, transfer connectors one at a time, and verify continuity before re-energizing. Choosing the OEM board ensures the precise timing and relay logic that aftermarket replacements frequently get wrong, while protecting your equipment warranty. Each board is quality-tested and backed by easy returns. In stock and shipping the same day on orders placed before 3PM CST, so you can resolve the fault and get the system online quickly. Order now to cut downtime and prevent repeat service calls.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB4ANB042015ABAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FB4ANB042015ABAA. 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 FB4ANB042015ABAA?
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?
