Furnace Not Blowing Air? It Could Be This Faulty Component


Your furnace can create heat all day long, but if it doesn’t blow the air into your home, the rest is pointless. Having a lack of good airflow isn’t just uncomfortable, it’s also dangerous for your furnace. And there’s usually one component that can be faulty and lead to your furnace not blowing air.

If you suspect that your furnace is not working as it should, our team can help. We offer Riverside furnace repair, and our expert team can inspect your furnace and offer a solution. In the meantime, you can keep reading to learn more about why your furnace may not be blowing air. 

About the Furnace Blower

The blower inside of your furnace is a motor fan that blows air across coils that heat up to warm the air. Then that heated air gets dispersed into your home using the ductwork system that accompanies your furnace. Without the blower, the heated air just stays inside out of your furnace. if this happens, it can actually cause your furnace to overheat since the warm air is not moving out of the system.

Furnace Blower Problems

The most obvious component to look at would be your blower itself. If the fan is broken, it won’t turn to channel air through your ductwork and into your home. It’s also possible that a fan blade gets bent and impacts how well the blower can work. 

If the problem is with the blower motor itself, there are a couple of reasons it may not be working. Lubricants can wear down over time as dust and dirt get in the crevices of furnace components, meaning that your fan won’t turn as easily. Lubricant is crucial for parts working together smoothly without grinding or getting stuck. 

It’s also possible that a fan belt is loose or snapped off completely. Fan belts are stretchy and wear down over time, leading to warping if they stretch too much. If the belts dry out and lose their elasticity they can snap and stop working completely, which can be very dangerous. 

Another Common Furnace Problem

But the blower isn’t the most frequent problem component that we see. The most common reason for your furnace not to heat your home actually has nothing to do with your furnace at all. Instead, the fault may be with your thermostat. If your thermostat doesn’t communicate with your furnace, the blower may not turn on to heat your home. Thermostat problems that can impact your furnace blower include:

  • Low batteries that need to be changed
  • Miscalibration that means your thermostat can’t communicate with your furnace
  • Temperature or heat settings aren’t correct
  • The date and time on a smart thermostat are incorrect

The good news is, thermostat problems can be easily solved. Our team can change the thermostat batteries, recalibrate the system or replace it with an updated thermostat.
