Dirty Filters

Dirty filters can cause air to have a hard time getting to your furnace. It is important to change your filter regularly so that it stays clean and helps your furnace to do its job properly.

The High Limit Switch

If your furnace overheats, the high limit switch will kick on. This is a safety feature that will turn your furnace off. A professional can determine why your system keeps turning on and off so that you can have peace of mind.

Flame Sensor

Your flame sensor is what properly gauges how much gas is going to your furnace. It is another safety feature that helps your furnace to be able to perform its best. If it gets dirty over time, it won’t be able to do its job right. That means that it won’t be able to tell how much gas the flame is using, so it will make the gas valve stop supplying gas to helps prevent excessive gas buildup.

The Furnace Blower 

Your furnace can run even if your furnace blower is not working right. If your motor is not working properly, heat will build up inside of your furnace instead of being blown over your heat exchanger. This will also cause problems with your safety features since your furnace will not be working properly. A specialist for heater repair in Norristown can help you figure out if your furnace blower is working the way that it needs to be or not.
