OEM Carrier Control Board CB-FX4CNF06B for Model FX4CNF060000AAAA

This genuine OEM Carrier control board is the central electronic controller for the FX4CNF060000AAAA fan coil unit, overseeing blower start-up, multi-speed fan operation, and the system's safety interlocks. A failing board often produces a dead blower, unpredictable fan cycling, or a unit that no longer responds to the thermostat. Made to Carrier's original specifications, this replacement supplies the exact relay capacity, terminal arrangement, and control firmware the FX4CNF060000AAAA needs, eliminating the erratic behavior that aftermarket universal boards can introduce. The replacement is a moderate-difficulty repair best performed by a licensed HVAC technician and usually takes 30 to 45 minutes: cut power at the breaker, photograph the existing harness, transfer each plug to the new board, and secure it to the factory standoffs. Check all connections carefully before restoring power. Installing the OEM board keeps your warranty valid and protects neighboring electronics from voltage faults. This control board is in stock and ships same-day on orders placed before 3PM CST, getting your system running again quickly.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FX4CNF060000AAAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FX4CNF060000AAAA. 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 FX4CNF060000AAAA?
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?
