Bard 9043-100 - Vent Limit Switch
The Bard 9043-100 vent limit switch is an OEM safety control used on select Bard SG and ESG gas heating sections in wall-mounted HVAC equipment rated from 40,000 to 140,000 BTU input. This switch is designed to monitor vent temperature conditions and open the circuit if unsafe heat levels occur, helping protect the heat section and maintain proper, safe operation when draft or venting problems develop. If you are troubleshooting nuisance shutdowns, vent safety trips, or intermittent heat operation, replacing a weak or failed vent limit with the correct Bard 9043-100 helps restore factory-correct safety performance and dependable heat calls, but always verify compatibility by model and serial and confirm the venting system and airflow are correct before returning the unit to service.
