8407-035 OBSOLETE
- Transformer 208/240-24 50VA
Bard part number 8407-035 is an OEM control transformer that steps 208/240 VAC down to 24 VAC at 50 VA to supply stable low-voltage power for the unit’s control circuit, such as contactors, relays, and safety devices in compatible Bard wall-mounted HVAC equipment. If your system has no 24-volt control power, intermittent control operation, or a repeatedly tripping low-voltage protection device, a failing transformer is a common root cause, and replacing it with the correct Bard-rated component helps restore proper control voltage under load. This part number has been discontinued by Bard and is commonly superseded by Bard 8407-068BX, so confirm the replacement part and wiring match your unit’s model and the original primary tap selection before ordering.
