Common Reasons Your Furnace isn’t Heating

When you turn on your furnace and notice that it isn’t blowing hot air, then you’re probably worried. Note that there are a lot of things that can cause your furnace not to heat properly. You might have problems with the flame detector, filter, gas supply, or more.?

Today, we’re going to share with you some common reasons why your furnace is not heating. 

You Haven’t Turned on The Furnace Switch 

Before you call a professional to come to check out your furnace, be sure to check the simplest things first. For example, is the furnace switch turned on?? 

Often, people assume that their furnace is not working because it’s old or needs repairs when they just forgot to turn on the switch.? 

So, take a moment to check these basic things before assuming the worst. In addition, be sure to check the thermostat to see if it’s set correctly. If neither of these is the issue, you can start looking at more complex problems, such as a clogged burner or faulty pilot light.? 

But again, rule out the basics first before anything else. 

The Thermostat Is Set Too Low 

If your furnace is not heating, it may be because the thermostat is set too low. You should first check the thermostat to see if it is set to the correct temperature. If it is, then you may need to adjust the settings.? 

If you have a programmable thermostat, you can typically set the temperature for different times of the day. Also, check the battery to make sure it is working correctly. If the battery is dead, it will need to be replaced. 

?Finally, if the furnace still does not work, you may need to call a professional for help. 

The Filter is Dirty 

If you ask, “why isn’t my furnace heating,” there’s a good chance that the answer is a dirty filter. A furnace relies on a steady supply of air to function correctly, and a clogged filter can restrict airflow and cause the furnace to overheat.? 

In some cases, a dirty filter can also cause the furnace to cycle on and off more frequently, leading to increased energy costs. Fortunately, changing a furnace filter is a relatively simple task that most homeowners can easily accomplish.? 

However, if you need help changing your furnace filter, you can consult your owner’s manual or contact a professional. 

Other Reasons 

As mentioned earlier, there are many reasons your furnace is not heating correctly. The ones mentioned above are the most common reasons. However, there are other things to consider as well. These things include: 

  • The circuit breaker has tripped.? 
  • The pilot light is out.? 
  • The gas valve is closed.? 
  • The furnace isn’t getting enough power.? 
  • Something is blocking the airflow to the furnace.? 
  • The burner assembly is clogged with debris. 

If none of these problems is causing your furnace to not heat up, you can contact a professional for help.
