OEM Carrier Control Board for Model FB4ANB060020ABAA Fan Coil

This genuine OEM Carrier control board is the factory-specified replacement for the FB4ANB060020ABAA fan coil unit and acts as the central controller for your air handler. It governs blower activation, fan speed staging, thermostat signals, and built-in safety logic, ensuring every heating and cooling cycle runs correctly and safely. Telltale signs of a bad control board include a non-functioning blower, unresponsive thermostat calls, repeatedly blown fuses, relay chatter, or visible burn marks on the board. Made to Carrier's exact specifications, this board guarantees the proper connector layout, relay ratings, and firmware your FB4ANB060020ABAA requires—accuracy that aftermarket boards rarely match. Because it manages line voltage and multiple wiring harnesses, installation is best performed by a licensed HVAC technician who can label and transfer connections precisely with power safely disconnected. Choosing OEM protects connected components and preserves your equipment warranty. In stock and ready to ship same-day on orders placed before 3PM CST, getting your system back online with minimal delay.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FB4ANB060020ABAA Fan Coil?
Yes. This is the factory-specified OEM control board for the Carrier Model FB4ANB060020ABAA Fan Coil. 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 FB4ANB060020ABAA Fan Coil?
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?
