Bard 8407-072 - 460VAC to 24VAC Control Transformer
Bard part number 8407-072 is an OEM control transformer used in Bard wall-mounted air conditioners to step down a 460VAC primary supply to a 24VAC secondary for powering low-voltage controls like contactor coils, relays, and safety circuits. Rated at 75 VA, this transformer helps maintain stable control power so the unit can start, run, and respond correctly to thermostat and control signals. If you are troubleshooting low or no 24V in a 460V Bard system, replacing the transformer with the correct OEM 8407-072 is a common, fit-critical repair, and you should confirm primary voltage and VA requirements against the unit wiring diagram before ordering.
