All You Need to Know About the Furnace Limit Switch

As a homeowner, the last thing you want is a furnace that malfunctions all of a sudden during the colder months. One small, crucial component that ensures your furnace runs safely is the furnace limit switch. In this article, the local heating and air conditioning experts at Perfect Degree HVAC explain the importance of this component and how to keep it in tip-top condition. 

Understanding Furnace Limit Switch

The limit switch monitors and controls the heat temperature inside your furnace. If the temperature inside the unit becomes excessively high, this component interrupts the gas supply, shutting down the system. This safety mechanism prevents overheating and potential fires.

Signs and Risks of a Failing Furnace Limit Switch

Despite the limit switch’s crucial role, it can sometimes go awry. If your furnace does not start, stops suddenly, or even continuously runs without generating heat, one of the likely reasons is a malfunctioning limit switch.

This issue is not something to ignore, as it puts your furnace at risk of overheating. Prolonged overheating can cause costly damage and even risk a house fire. It also underscores the fact that maintaining your heating system isn’t just for comfort—it’s about your family’s safety, too. When you encounter these anomalies, be sure to call professional HVAC contractors right away. Their skills and expertise can help minimize heating issues and ensure consistent comfort during the fall and winter months.
