The Bard 9043-055 Door Interlock Switch Assembly (300229) is an OEM safety switch used in Bard wall-mounted HVAC equipment to interrupt power when the service door or access panel is opened, helping prevent the unit from operating while components are exposed. Replacing a worn or damaged interlock switch can restore proper safety shutoff and help eliminate nuisance operation issues tied to a misaligned or failing door switch. Match this part number to your Bard model and wiring configuration to ensure correct fit and reliable system protection.
Please call for available options or find replacement parts.
