What are the Safety Features of a Furnace in Aliante, NV? Pressure & High Limit Switch, Flame Sensor & More

When you think about the furnace in your home, you want to know that it is as safe as possible. Because your furnace burns fuel as it heats, you need to make sure that there aren’t any harmful gases that are leaking into the air you’re breaking. You also want to make sure that as far as electricity goes, there isn’t a risk of your house catching on fire. Within every furnace, there are certain safety measures that are in place to make sure your home is as safe as possible when your furnace is on. Hal Mechanical is here to talk about and explain these safety features, and why they are there.

Pressure Switch

Because your furnace burns fuel to keep your home warm, it is important that the exhaust that this creates makes its way outside. This is done with a flue. Your flue needs to be working properly without any blockages that get in the way of that exhaust making its way out. This is where the pressure switch comes into play. The pressure switch measures the air pressure from the fans in your furnace. If there is a blockage in the flue, it will trip the switch and the furnace will shut down.

Flame Sensor

If you have a modern furnace, it more than likely has an instant ignition system to start the furnace. It is important that there is a flame present to ignite the fuel so that the fuel isn’t leaking into the air and rest of the furnace. The flame sensor is important in that it makes sure that there is a flame present. If there isn’t, the furnace won’t be able to turn on to keep your home safe from these gases.

Roll Out Switch

No only is it important that the gas has a way of being ignited, it is important that the flame stays in the combustion chamber. When the flame escapes this chamber and makes its way into other parts of the furnace, it is a major safety issue. In fact, if the roll out switch keeps on tripping, it is usually because there are big problems like a blockage in the heat exchanger, improper gas pressure, or a failed heat exchanger all together.

High Limit Switch

You never want your furnace to get to the point that is overheats either. If your furnace gets too hot, it can be at risk of starting a fire in your home. To make sure this doesn’t happen, every furnace has a high limit switch that will shut the furnace down if it senses that the furnace is starting to get too warm.
