• TRANSFORMR 120/24V 40VA 207023

The Bard 8407-033 is an OEM 120V to 24V control transformer rated at 40VA (207023) used to supply stable low-voltage power for relays, contactors, and control boards in Bard wall-mounted HVAC equipment. A weak or failed transformer can cause intermittent controls, chattering contactors, blown low-voltage fuses, or a complete loss of 24V, so replacing it with the correct Bard part helps restore proper system operation and protects sensitive control components. Confirm the primary voltage at your unit is 120V and match the VA rating and wiring terminals to your existing transformer or the unit wiring diagram to ensure proper fit and safe operation.
