Common Problems That Occur With AC Capacitors

One of the most important parts of any home comfort system is the capacitor. This complex component can be found in several shapes, sizes, and location within in an air conditioning system, so it’s important to have a little capacitor know-how to be prepared if a problems arises.

Air Conditioning Capacitors

Air conditioning capacitors encounter problems from time to time. Considering there are multiple capacitors within an air conditioning system, it’s important to understand each variety and the purpose they serve. Although there are multiple kinds of capacitors within an air conditioning system, the job of a capacitor is ultimately to help start or run the motor. Here are the capacitor varieties within the typical AC:

Start Capacitor: Some air conditioning systems contain a start capacitor, which helps to jump-start the motors.

Indoor Blower Motor Run Capacitor: This capacitor is a small, single capacitor that helps start and run the indoor blower motor.

Outdoor Fan Motor Run Capacitor: This is a tiny capacitor that helps start and run the outside fan, which blows air through the outside coils.

Compressor Motor Run Capacitor: This capacitor encounters problems most often. Most air conditioning systems contain two capacitors into one.

Why Air Conditioning Capacitors Go Bad

The most common problem an air conditioning capacitor can encounter is a decline in strength, often due to general wear and tear. When capacitors are made, they’re labeled with specifications detailing their operating range. Once the capacitor begins to fail and stray from its operating range, it can cause a variety of issues within an air conditioning system. Each capacitor has an important job to do in order to provide cooling comfort to a home.

How Capacitors are Fixed

In order to fix a capacitor, you must first determine which capacitor is malfunctioning. The next step is removing and replacing the capacitor. Fixing a capacitor can be tricky considering there are multiple capacitors within a single air conditioning system. Capacitors also house electricity and can shock you if they are not carefully handled. For this reason, it’s a good idea to hire a professional technician to diagnose and repair the issue to prevent further damage.
