This premium Fan and Limit Switch is an essential safety and operational component for residential forced-air furnaces. It serves a dual purpose in your heating system: regulating the blower fan to ensure it only circulates warm air and acting as a high-limit safety cut-off to prevent the unit from overheating. By monitoring the temperature of the heat exchanger, this control switch protects your HVAC equipment from thermal damage while optimizing energy efficiency and airflow. If your furnace fan is running continuously or the burner is cycling off prematurely, a replacement fan disc limit control is a common solution for restoring reliable heating performance and safety.
