Why Does My Furnace Keep Turning On and Off?


Last weekend, we saw blizzard “Jonas” tear through the Northeast. Heavy winds, freezing temperatures and feet of snow made it almost impossible to leave the house! (Maybe some of you consider this a good thing.)

Needless to say, this week our furnaces have been working harder than ever. As your machine kicked into high gear to keep your home warm, did you notice anything odd, like your furnace turning on and off throughout the day? If so, don’t worry – this is normal behavior for a furnace. But when it happens too much, there could be an underlying issue.

In this blog, our Newark HVAC business will explain some of the reasons your furnace may be acting finicky and provide some troubleshooting tips for restoring proper function.

Furnace Troubleshooting Tips From The #1 Newark HVAC Company

The first thing to know is your furnace is supposed to turn on and off from time to time. To keep your home at a comfortable temperature, it should cycle on and off three to six times every hour. However, if it’s starting up and shutting down for very short periods of time, you’ve got an issue called short cycling. Here are a few common causes of short cycling:

  1. Dirty Air Filters – If you’ve been reading our blogs, you know that dirty air filters can be the cause of many different furnace problems. A clogged air filter sends the wrong message to your furnace, so replace them every season and check them monthly.
  2. Defective Thermostat – Is your thermostat switched to heat? Make sure it is before declaring a problem. Also, if your thermostat is in direct sunlight, this could be causing it to tell your furnace it’s time to shut off.
  3. Flame Sensor Corrosion – A flame sensor is one of the many safety features in a gas furnace. Burning fuels produce small amounts of water, which could cause your metal flame sensor to rust. Call a professional to come clean it for you, since doing it yourself could be dangerous.

Other causes can include an improperly sized furnace or a foreign object stuck in the air vent or chimney. If the short cycling goes unfixed, it can cause permanent damage to your furnace and jack up your heating bill. So be sure to call Gold Star, your trusty Newark heating experts to get it repaired right away.
