A Guide to Capacitor Problems for AC

Video Source

AC service is a modern amenity that many of us take for granted. When something goes wrong, our comfort and air quality plummet. This video shows how one AC serviceman tackles issues with an air conditioner capacitor so you can identify problems in your own home.

A faulty capacitor is one of the most common issues with air conditioners. The capacitor is a motor starter for your AC unit. It can overheat and pop, cutting power off to the motors of your AC unit.

The serviceman will first check the electronics with a multimeter to make sure the capacitor is sending power the way it needs to be. Other parts of the unit, like the fan, may be working, but if the capacitor isn’t running you will be without cool air.

To fix a capacitor with low or no power, it’s best to replace it. This will fix any problems you are currently having and maintain your air conditioning down the line. If you let it go, the problem can grow larger and affect more components of the AC unit, leading to a full unit replacement.
