Troubleshooting a Short-Cycling Furnace

Troubleshooting a Short-Cycling Furnace

If your furnace repeatedly turns on and off for several seconds, or even minutes, it is “short-cycling”. A short cycling furnace can result in a number of inconvenient problems, but it is also difficult to define what qualifies as a short-cycling furnace. It is normal for your furnace to turn on and off, especially if you are requiring it to produce a greater amount of heat. When determining of a furnace is “short-cycling” the focus should be on how long your furnace runs when it does turn on. A “short-cycling” furnace will normally only run for less than two minutes before shutting off. In today’s article, Right Away Heating will discuss what may be causing your furnace to “short-cycle”.

Check Your Thermostat

Overtime, thermostats wear down and begin to function poorly. Dysfunctional thermostats can impact your entire heating system. For this reason it is important to regularly have your heating system inspected by certified professionals. If your thermostat needs replacement,  our team of professionals, at Right Away Heating, can help.

Check Your Air Filter

A clogged furnace air filter often results in a “short-cycling” furnace. The filter can become a wall of debris, blocking proper airflow to your furnace. Consequently, when your filter becomes clogged, not enough air gets to the tubes that connects your heating system. These tubes don’t get the opportunity to bring heat into your home. This may lead to overheating, and eventually, a “short-cycling” furnace. Prevent a clogged air filter by regularly cleaning your furnace by yourself or with the help of Right Away Heating professionals.

Check the Furnace Blower

Occasionally, a furnace may “short-cycle” if the blower motor is off. The easiest way to check if your motor is working is by putting your hand under the vent and feel if there is air coming out.  If the the vent’s air is weak, or nonexistent, then this is likely your furnace’s problem. If your furnace blower is not operating you must call a team of HVAC professionals. Put your trust in Right Away Heating.
