The Bard 8407-071 is an OEM 75 VA control transformer used in Bard wall-mounted HVAC equipment to supply 24-volt power for low-voltage circuits such as thermostats, relays, and control boards. It is designed for units with 208/240V primary power and provides a stable 24V secondary output to help restore proper system operation when a failed or overheating transformer causes loss of control voltage, nuisance fuse trips, or no response from the controls. For best results, confirm your unit voltage and match the VA rating to the original, then verify wiring connections against the Bard unit schematic before energizing.
