5 Reasons AC Blower Motor Trouble

A well-functioning AC blower motor is a crucial part of your air conditioning unit. It is the main part behind the movement of conditioned air in your home, and it’s the difference between “ahh” and “ugh” in your home’s temperature.

Signs that your unit may be experiencing a fan motor malfunction include:
- Weak/No Airflow Through Ducts
- Warm Air
- Buzzing Noise

If you suspect or know that you have an air conditioner blower motor issue, it is probably being caused by one of five problems. J Blanton is here to give you an overview and tell you how to solve the issue as well as how to prevent it in the future.

Issue #1 - Old Age

Age is a very significant factor for HVAC units. No matter how much maintenance you do or don’t put into your air conditioner, the parts will eventually begin failing, leading to a system failure. If your air conditioner is over 15 years old, you might be looking at a full system replacement.

Issue #2 - Failed Bearings

Sometimes inconsistent lubrication can cause failed bearings, a small but important piece. The failure causes the motor to become stuck.

Issue #3 - High Amp Draw

Your HVAC system might draw a stronger current if it is improperly sized, which can cause damage. This can also happen if it is on all of the time and a few other instances. If it overloads, you might notice an electrical burning smell. Your circuit breaker may catch this before it happens, in which case you will notice repeated tripping when you run your AC.

Issue #4 - Power Surges

After a power outage, electricity often rushes back to your home and can overload your HVAC system. You might also experience a surge if lightning was responsible for the outage.

Issue #5 - Dirt Accumulation

Dust and dirt will collect on all parts of your air conditioning unit over time, including your blower motor. This has a significant effect on the performance.
