This OEM Carrier transformer is the authentic low-voltage power replacement for the FB4CNF036T10ABAA fan coil air handler. It steps down incoming line voltage to the 24V control signal that powers the thermostat, contactor, and control board. If your unit has lost 24V control power, shows a dead thermostat, or won't answer heating or cooling calls, the transformer is a likely culprit. Built to exact factory specifications for the FB4CNF036T10ABAA, this component provides a precise fit and trustworthy performance that generic substitutes simply cannot deliver. Installation is moderate and should be performed by a licensed HVAC technician: disconnect power, transfer the labeled primary and secondary wiring, and remount in the original position, generally in less than 30 minutes. Get your air handler's control circuit back to safe, reliable operation with a genuine Carrier part. In stock and shipping same-day on orders placed before 3PM CST. Rely on authentic OEM quality for long-lasting durability and consistent comfort all year long.
