What Is a Limit Switch?
A limit switch is a primary safety control in gas furnaces and heating systems. It monitors heat exchanger or plenum temperatures and automatically shuts off the burner if temperatures exceed safe operating thresholds. This prevents overheating, heat exchanger damage, and potential fire hazards — protecting both the equipment and the occupants of the building.
