OEM Carrier Control Board CESO110074 for Model FC4BNF036000AEAA

This OEM Carrier control board is the genuine factory replacement for the FC4BNF036000AEAA fan coil unit. Acting as the command center of the air handler, the board governs blower motor timing, fan-speed staging, safety lockouts, and communication with the thermostat and condensing unit. A failed board often presents as a blower that won't energize, erratic or continuous fan operation, repeated fuse failures, or a system unresponsive to thermostat demands. Because it is built to Carrier's exact specifications for the FC4BNF036000AEAA, this board provides the precise sequencing and compatibility that aftermarket alternatives can't reliably deliver. Replacement is a moderate-difficulty repair best left to a qualified technician, typically requiring 45 to 60 minutes to transfer and verify wiring, mount the board, and test operation — always with power disconnected at the breaker. Snapping a photo of the original wiring before removal speeds up reinstallation and prevents mistakes. In-stock orders placed before 3PM CST ship the same day, restoring proper, code-correct system control without a long wait.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FC4BNF036000AEAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FC4BNF036000AEAA. 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 FC4BNF036000AEAA?
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?
