4 Signs of an AC Blower Motor Having Problems

The blower motor is an important part of the air conditioner in your home. If you’re a resident of Greenville, NC, and your AC blower motor isn’t working properly, you’ll notice warning signs eventually. Here are four signs that your air conditioner blower motor might be having problems:

Low or No Airflow From Vents

The AC system is responsible for circulating air through the system and into your home. Therefore, if you notice that there is low or no airflow from your vents, it’s an indication there may be a problem with your blower motor that needs repair or replacement by a professional.

Making Strange Sounds

If your air conditioner is making strange noises, it shows that your blower motor is having problems. Common notifications include a rattling sound, indicating that the blower wheel or the bearings and bolts are loosening, or a grinding noise that points to the build up of debris on the blades.


An AC blower motor with problems will overheat due to things such as built-up dirt and grime or when it’s old and worn out. At times, the overheating leads to the development of a hot smell from the air vents. Overheating can cause damage to the bearings, windings and insulation.

Frequently Tripping Circuit Breaker

Your AC blower motor might also be having problems if the circuit breaker frequently trips. It could be because the motor is drawing too much power and causing an overload on the circuit because of a bad capacitor.
