What Causes Fan Motor Problems with My AC?

The development of affordable residential air conditioning in the 1950’s was one of the reasons so many people were willing to build their homes in beautiful southern Arizona. If you live here, you know all too well an AC is one of the most important parts of your house, keeping you cool throughout the year. If vital components of your air conditioner start to fail, you need to have the problem identified and fixed as soon as possible. For Phoenix AC repair, count on the skilled technicians at Goettl Good Guys Air Conditioning to get you out of the heat and back into the cool!

Fixing fan motor problems is a common repair we have to make.

Air conditioners use two fans: a blower fan inside, and a fan in the outdoor unit that helps with releasing hot air to the outside. Problems with the motors that run either fan will disrupt the heat exchange cycle necessary for your AC to work properly. One of the main reasons a fan motor might malfunction is dirt inside the cabinet. The air filter normally protects the AC interior from debris, but if it becomes clogged or breaks, pollutants forming inside can damage the motors and make them run less efficiently.

Like any motor, an air conditioner fan motor can become overheated if it works too hard and doesn’t receive proper maintenance. If your AC has worked for you most of the summer, the stress could cause the fan motors to burn out. We recommend scheduling regular maintenance, once or twice annually, to keep the motors in good condition so they last for many years.

If a fan motor isn’t starting at all, the trouble may not be in the motor itself, but the start capacitor. This cylindrical device, about the size of a soda can, sends the voltage to the motors that starts them working. Damaged wiring can cause a capacitor to fail, and the motor will not be able to start.

Prevention is the best way you can avoid troubles like these. Goettl Good Guys Air Conditioning offers a quality maintenance program that will keep your fan motors, as well as the rest of your AC, in tip-top shape.
