OEM Carrier Control Board CESO110074 for Model FB4ASF030000AEAA

This genuine OEM Carrier control board governs the core electronics of your FB4ASF030000AEAA fan coil air handler, managing blower activation, fan timing, safety circuits, and thermostat communication. A faulty board often causes a blower that won't run, unpredictable fan cycling, no response to heating or cooling calls, or diagnostic fault indicators. This factory-spec replacement is matched to the FB4ASF030000AEAA's exact connector layout and control logic, ensuring correct relay sequencing and seamless integration with your system. Installation is moderate—best for those experienced with HVAC wiring. Shut off power at the breaker, carefully label every connector, transfer each harness to the new board, and remount it, typically a 30 to 45 minute job. If you're not confident, a licensed HVAC technician can complete the swap quickly and verify operation. Manufactured to genuine OEM standards for long-term reliability and full compatibility with your Carrier air handler. This control board is in stock and ships same-day on orders placed before 3PM CST, helping you minimize downtime and restore dependable, comfortable airflow to your home without delay.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB4ASF030000AEAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FB4ASF030000AEAA. 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 FB4ASF030000AEAA?
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?
