Repairing An AC Unit

What Does An HVAC Condenser Fan Motor Do?

Located on the outside of the HVAC system, the condenser fan motor is a crucial element during the cooling process responsible for keeping the air conditioning cool when it is running. The condenser fan motor turns the fan that blows air across the condenser coil, which in turn cools the refrigerant, making it a liquid rather than a gas. When the motor overheats, the HVAC unit will no longer have a way to cool itself and can cause the system to fail.

Common Causes Of An Overheating Condenser Fan Motor

There are several causes of an overheating condenser fan motor, but the most common are listed below. If you notice any of these, be sure to contact our AC repair technicians right away.

  • Old, worn-out motors can give out or fail without proper maintenance.
  • A faulty capacitor can cause a motor to spin too slowly or stop it from turning.
  • Damaged wiring or circuits can cause the fan to run intermittently or stop altogether.
  • Insufficient space around the outdoor cabinet can restrict airflow, causing the fan motor to overheat.
  • A buildup of dirt and debris on and around the fan can cause the fan motor to overheat.
  • A lack of maintenance can cause the fan's motor to wear down faster.

Telltale Signs Of Overheating

A fan motor will overheat when it reaches a temperature of 150 degrees Fahrenheit, prompting the motor to stop running, stopping the HVAC system altogether, and possibly damaging other essential components. If you think your condenser fan is overheating, look for the following symptoms.

  • The top of the outside unit is hot, not warm, to the touch.
  • The cooling system runs, but any airflow coming out of your vents is no longer cool.
  • A steady buzzing or humming noise is coming from the outside unit.
  • There is a strong odor coming from the outdoor unit.

If you notice any of these signs, we recommend reaching out to an experienced HVAC company immediately to prevent further damage to your home's AC unit.
