Also known as the fan limit switch or simply the limit switch, it has two functions in the furnace's operation: This article describes in detail the testing and diagnosis of problems with warm air heating furnace combination controls, also commonly. A furnace fan limit switch is a crucial component in a heating system that helps regulate the temperature and airflow within the furnace. When air in the plenum reaches the high limit setting on the limit switch, the switch signals the control board to start the blower fan, which circulates air across the heat. This control also provides a safety limit that turns off the burner or furnace if temperatures at the furnace. Learn what a limit switch is, where it is, and how to replace it. The fan limit switch controls when the furnace blower fan turns on and off. It acts as a safety device, preventing the furnace.
