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 indicate 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 in the experts at Singletrack Electric & Heating at (303)215-9449 to properly diagnose and fix any issues that could be causing your blower fan not to operate properly.

  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 have gone dead, it can cause your thermostat to malfunction and not properly communicate with your system. If the thermostat is properly functioning, make sure it is set to the ‘heat’ mode and that the temperature is set higher than the current temperature of 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 make sure there are no switches that have been tripped or any blown 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 it doesn’t need a change. The air filter collects dust, dirt, and other debris, which can limit the airflow and place unnecessary stress on the blower motor. You also want to ensure the filter was inserted into your 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 will want to remove the blower cover, which is typically connected by a few screws in the front. Once the cover is removed, allow the blower to cool down to ensure it is safe to touch. If there is dirt or dust accumulated 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. Our HVAC technicians at Singletrack are highly trained if you feel more comfortable with an expert taking a look. Call us anytime at (303)215-9449, and we’ll get someone out quickly.
  1. While you have the blower cover off, you will also want to inspect the motor for any visible damage or signs of wear. You can also do a visual inspection of your furnace blower’s drive belt to verify that it is not worn down or cracked and needs to be replaced. If you do see any damage to the motor or worn-out or loose components, it’s best to call on the professionals at Singletrack Electric & Heating to handle any repairs – https://www.singletrackelectric.com/contact/
