This genuine OEM Carrier control board is the electronic core of your FX4ANB060000AAAA fan coil unit, handling blower relay control, sequencing delays, safety interlocks, and communication with the thermostat and outdoor unit. Signs of a failed board include a blower that will not run, erratic cycling, no response to thermostat demand, or diagnostic LED fault codes. This exact-fit OEM board restores the engineered timing and protection logic that aftermarket boards often cannot fully match, ensuring your system behaves as designed. The connector layout and firmware are matched to the FX4ANB060000AAAA for a confident, precise fit. The repair is moderately difficult and best left to a qualified HVAC technician: disconnect power at the breaker, document all wiring with photos, transfer connectors one at a time, and verify dip-switch and jumper positions against the unit's diagram. A dependable ground connection safeguards the new board. Built to Carrier OEM standards for reliable, long-term service. We have this control board in stock and ready to ship. Order before 3PM CST and it ships same-day so your repair stays on schedule.
