You might be asking yourself what a furnace blower fan is anyway. It is an electric blower that works with your furnace to distribute cool air so that your home can remain warm during the winter months. Dispersing the cool air allows your furnace to heat up more quickly and keeps your energy bills down. A blower fan also helps to circulate the heated air throughout the house by pushing warm air to the vents.


One of the most common signs that you have a problem with your blower fan motor or another piece of its assembly is an unusual odor or burning smell. This smell can come directly from the furnace and often will also make its way through your vents. When this blower fan stops doing its job, there can be a variety of reasons why.

Here are 8 common reasons your furnace blower motor isn’t working.

To verify if the fan is working, you can switch the fan on your thermostat to the ‘on’ position. If the fan starts running, this is an indicator that the problem is something other than the fan itself. If the blower fan does not spin, this could be an indication of a furnace blower motor failure.

It is important to address this issue promptly to restore the proper functioning of your furnace and restore warmth to your home. Call the Indoor Comfort Team at (314)230)9542 for assistance with diagnosing and fixing issues with your blower fan.

  1. If your furnace blower motor isn’t working, the first thing you will want to check is your thermostat and its settings. If the batteries in your thermostat die, it can make the thermostat not work right or communicate with your system. Check if the thermostat is working and set it to ‘heat’ mode with a higher temperature than the room.


  1. If your furnace blower fan is still not working, you will want to check to see if there are any power issues. First, check the circuit breaker to ensure that you have not tripped any switches or blown any fuses. You will also want to make sure that the furnace’s on/off switch on the unit is in the ‘on’ position.
  1. Restricted airflow can also cause the furnace blower to stop working. You will want to check your unit’s air filter to ensure you don’t have a clogged filter. The air filter catches dust and dirt, which can block airflow and cause motor problems.

You also want to make sure you inserted the filter into the unit correctly.  Check the arrows on the air filter to make sure they are pointing in the correct direction.


  1. Resetting the blower is the next thing to try if your furnace blower fan is still not working. To do this, you will first want to turn off the breaker connected to your furnace to make sure the power is off. Then, you should remove the blower cover, which is usually connected by a few screws in the front. Once you remove the cover, allow the blower to cool down to ensure it is safe to touch.

    If there is dirt or dust built up on the fan, you can use compressed air to clean it off. Once everything is cool, find the red reset button on the backside of the motor. You will want to push this button in to reset the furnace blower motor.
