Furnace Safety Shut Off

Imagine, on the other hand, that something goes wrong with your blower system. If your furnace is unable to move all of the heat that it is generating out into your home, the combustion chamber will continue to become hotter and hotter. Once this heat reaches a certain threshold, it will activate the high limit switch, which in turn will shut down the flow of gas into the furnace.

In this way, the high limit switch acts to prevent a potentially dangerous scenario. You see, if the temperature in the furnace was allowed to keep growing higher and higher, eventually it would cause a devastating explosion to occur. If you have noticed that your furnace seems to be turning on periodically, yet no heat is coming out through the registers of your home, it’s high time to have a professional come check for problems in your blower system. Until you do, the only thing standing between your furnace and disaster will be the high limit switch.

Understanding Your Furnace’s High Limit Switch

Your furnace’s principal job is to provide your home with the heat it needs. Yet a furnace also has to be capable of performing the secondary function of keeping you and your family safe. One way it does this is through the incorporation of the component known as a high limit switch. If you would like to learn more about how this component works, read on. This article will discuss the role of the high limit switch in your furnace.

Normal Furnace Operation 

The high limit switch is located inside the heart of your furnace. It’s job is to monitor the temperature of the gas being combusted there. So long as the blower motor turns on correctly, distributing heated air throughout your home, the high limit switch will allow the furnace to keep operating. That’s because the temperature will remain within an appropriate range.
