This OEM Carrier transformer converts incoming line voltage into the 24V control power that runs the thermostat, control board, and relays within the FY5BNF036000AAAA fan coil unit. If your system is completely unresponsive, repeatedly blows the control fuse, or the thermostat shows no power, a failed transformer is often the cause, and this genuine replacement restores reliable low-voltage supply. It is a direct-fit match for the Carrier FY5BNF036000AAAA, with the correct windings, voltage rating, and mounting bracket. Installation is moderate difficulty and best done by a qualified HVAC technician, generally taking 20 to 40 minutes to disconnect power, swap the labeled leads, and secure the unit. Genuine OEM construction ensures accurate voltage output and durable performance that protects the entire control circuit. We keep this transformer in stock for quick shipment. Orders placed before 3PM CST ship same-day, restoring power to your Carrier system without delay. Rely on this factory-authentic transformer for safe, steady 24V control operation.
This part is compatible with Carrier model FY5BNF036000AAAA.
