Common AC Problem: External Fan Not Working

August 15, 2018

During the summer, your air conditioner (AC) works harder and longer.  That high demand may cause a problem to rear its ugly head.  In this multi-part post, we’ll take a look at some of the most common AC problems, talk about the possible causes, and provide suggestions for tackling each problem.

External Fan (Compressor) Not Working

Check all around and inside the outdoor unit.  Verify that the fan blades are unimpeded.  It could be that the outdoor unit sustained damage due to falling debris from storms.  Be sure to keep the area around the outdoor unit clear of debris and check it often throughout the summer and fall.  If there are no obstructions and the fan blades are not turning, it could be caused by a lack of power to the system.  Cycle the power by turning the circuit breaker off and back on again, then set the thermostat lower than the current inside temperature and wait 2-5 minutes.  If you do not hear the compressor kick in and the fan blades start to turn, you probably have a faulty motor or compressor, and will need to contact a service professional.

Avoid Summer AC Problems

Summer can be the best time of the year, so don’t let air conditioning problems hinder you from enjoying it.  Be sure to get annual AC maintenance visits, so it will run efficiently and be ready for the high demand of the summer’s heat.  If you live in the Nashville area and experience any heating or cooling problems, call on Interstate AC Service at (615) 832-8500.
