What Would Cause a Furnace to Short Cycle in Summerlin South, NV & How to Stop Short Cycling

Having your furnace turn on only to shut off shortly after is frustrating. It ends up costing you more money due to inefficiency and leaves your home feeling far from comfortable. Short cycling is an issue that is usually associated with having a furnace that isn’t the right size for your home. However, this isn’t the only problem that can lead to short cycling. Hal Mechanical is here to talk about some of the other problems that can cause your furnace to short cycle.

Dirty Air Filter

The filter in your furnace plays a large role in how well the furnace can operate. If your furnace isn’t getting proper airflow because of a filter that is filled with dust and debris, it can not only shorten the lifespan of your furnace, but it can lead to short cycling as well. This is because the furnace will shut off to avoid overheating issues.

Failing Furnace Flame Sensor

There is an important safety feature in your furnace that ensures there is always a flame that is burning the natural gas during operation. This is important because of the dangers of natural gas building up inside your unit. As that sensor gets older, it can start to deteriorate or get covered in dust which can lead to malfunctioning. That leaves your furnace shutting off abruptly. You can stay on top of this problem with regular maintenance to make sure there aren’t any issues with the flame sensor at the beginning of the winter season.

Damaged Igniter

Some furnaces have an intermittent pilot light while others have a hot surface ignition system. In the hot surface ignition system, there is a component that gets extremely hot and ignites the natural gas. If there is something wrong with that ignitor, the furnace will shut down shortly after starting up because the gas won’t be able to catch on fire. This is all in place to keep natural gas from building up inside your heating system.

Blocked Flue / Vent Pipe

Because of the dangerous gases that are a byproduct of the heating process, it is essential to have those gases vent to the great outdoors. When there is a blockage in the flue or vent pipe, it can cause these gases to start to build up inside your system. Luckily, there is a flue limiter that works to shut off your furnace when it detects these dangerous gases. This is a crucial part of keeping your home protected from carbon monoxide build up which can be deadly.
