OEM Carrier Control Board CESO110074 for Model FX4BNB060000AAAA

This OEM Carrier control board serves as the command center of your air handler, managing blower timing, fan-speed staging, safety interlocks, and thermostat communication. Built as a direct-fit replacement for the Carrier FX4BNB060000AAAA fan coil unit, it restores precise, reliable control so your system heats and cools exactly as designed. Common symptoms of a failing board include a blower that won't start, runs nonstop, or fails to respond to thermostat calls — clear signals that a genuine replacement is needed. Manufactured to exact OEM specifications, this board matches the unit's original wiring harness and factory programming for seamless integration. Installation is an advanced repair best performed by a qualified HVAC technician: disconnect power, photograph and transfer each wiring connection carefully, and install the new board in about 30 to 45 minutes. Avoid the compatibility headaches of universal boards with a factory-grade part that fits and functions like the original. In stock and ships same-day when ordered before 3PM CST.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FX4BNB060000AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FX4BNB060000AAAA. 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 FX4BNB060000AAAA?
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?
