How Does A Furnace High Limit Switch Work. From understanding its role to recognizing signs of malfunction, we have all the information you need to keep your furnace running safely and efficiently. You need a furnace limit switch to protect your home from the heat exchanger overheating and causing a fire. The furnace blower fan is meant to remove the heat from that section, but the furnace will overheat if there is an issue with the airflow. The high limit switch detects if there is a high temperature in your furnace’s heat exchanger. 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 exchanger for warming, then on to the rest of the house through ductwork. Compliance with safety regulations is essential for home security, with the “limit switch” emerging as a critical component of a furnace. The limit switch activates the blower fan and deactivates the burners when the furnace temperature reaches a dangerous level. A cracked heat exchanger will allow flue gases to infiltrate the supply air into your home. Excessive temperatures in your furnace might cause the heat exchanger to crack. What is a furnace limit switch and how does it work? The high limit switch will reset automatically when the temperature inside of the heat exchanger falls below a certain level. A furnace limit switch keeps your furnace running safely by monitoring the air temperature. The high limit switch helps prevent damage to your heat exchanger by shutting down your furnace if it gets too hot. In this article, we’ll dive into what a furnace limit switch is, how it works, and why it’s essential for your furnace’s safety.
