Bard part 9043-099 is an OEM vent limit switch used on Bard wall mounted gas electric units in the SG and ESG series with heating capacities listed from 50,000 through 140,000 BTU. This temperature safety switch helps protect the unit by monitoring vent or flue temperature conditions and opening the circuit when limits are exceeded, which can prevent overheating related issues tied to venting, airflow, or combustion problems. Use this Bard replacement when diagnosing a vent limit fault, nuisance shutdowns on heat, or a switch that is out of calibration, and always verify the correct part by matching your full model and serial number to the Bard parts list before ordering for proper fit and safe operation.
