Bard 8407-030 - Control Transformer (MSR)

Bard part number 8407-030 is an OEM Transformer MSR (also referenced as 20593-002) used in the unit control panel to convert incoming line voltage into the low-voltage power your Bard wall-mounted air conditioner relies on for controls, relays, and safety circuits. Replacing a weak or failed control transformer can resolve symptoms like dead low-voltage terminals, intermittent call-for-cooling issues, or nuisance control dropouts. As a genuine Bard replacement, 8407-030 is intended to match the electrical fit and mounting style used in compatible Bard equipment, but you should confirm voltage and model compatibility by checking the unit wiring diagram and parts list before ordering.
