What Causes a Furnace Blower to Stop Working?

It’s winter.  Inside it should be warm, but you feel chilly.  Then you notice that there is no sound coming from your furnace and realize that your system’s blower has stopped working.  No blower means no warm air is being delivered through your vents to your rooms and it is getting colder by the hour.

There are many reasons why a furnace blower will stop working.  Some are easy to fix.  Others will require a furnace service call from one of our technicians to dig into the problem and make the needed repairs or replace parts.

First, the easy fixes.  Have to checked to see if your circuit breaker has tripped on your electrical panel? There should be a dedicated circuit for your furnace and if it has tripped, reset it.  Wait a few minutes to see if your furnace cycles back on and the blower starts once again.

Sometimes the furnace blower isn’t working because the thermostat is set too low. Over the summer or more recently, someone may have accidentally lowered the thermostat temperature.  With all the new digital thermostats and digital controllers, this can and does happen. 

The third easy fix is a clean furnace filter.  If air does not move freely through the air filter, you will not get the flow of air you need to keep your home at the comfortable temperature you have set on your thermostat.  It is a good idea to replace a furnace filter once a month in wintertime when you use your furnace a lot.

Some blower malfunctions are serious enough that you should give us a call to take a look at the system.  Perhaps there is a wiring issue causing the blower to stop working.  The motor might have a problem and requires service.  Our goal is to get your furnace back working quickly, reliably and safely so that you can remain comfortable no matter how cold it gets outside.
