If you're reading this, then you probably suspect there's something wrong with your motor capacitor.

Are you wondering how to tell if your capacitor is failing?

In this helpful article, you will find out:A capacitor is an energy storing device. It is a medium by which energy is stored to either be released suddenly or over a period of time. The energy or capacitance of an electric capacitor is measured in the form of micro-farads. Essentially, two plates are separated by a material known as a dielectric or insulator. These insulators can be mica, ceramic, porcelain, Mylar, Teflon, glass, or rubber. Capacitors will also limit the current. They can be used to store voltage or build it up until the call for it to be released is present.The schematic symbol for a capacitor actually closely resembles how it's made. A capacitor is created out of two metal plates and an insulating material called a dielectric. The metal plates are placed very close to each other, in parallel, but the dielectric sits between them to make sure they don't touch.

The dielectric can be made out of all sorts of insulating materials: paper, glass, rubber, ceramic, plastic, or anything that will impede the flow of current.Electric motor start-run capacitor selection guide:

This article explains how to select an electric motor start capacitor, hard start capacitor, or run capacitor that is properly rated for and matches the requirements of the electric motor such as an AC compressor motor or fan motor where the capacitor is to be installed.The capacitors are an essential part of your air conditioning system. The capacitors are small cylindrical shaped containers that lie inside the housing of the air conditioner. The main purpose of them is to store energy and provide it to the motor upon start-up and when running. They are called a start capacitor and a run capacitor.When your air conditioner first turns on, it requires a massive amount of energy to begin its cycle. Often, your home’s electrical system can’t handle the large load of energy needed to get the system going. This is where the start capacitor comes in. Once the AC is turned on, the start capacitor sends an immediate electrical charge, or boost, to get the rotation of the motor started. Once the proper amount of torque, or energy, is pushed to the motor, then the start capacitor shuts off.

Once the system has started and is operating, the run capacitor takes over and provides the extra power to run the air conditioner for long periods of time. When the air conditioner is running, both capacitors create and store energy for the push for the next cycle. Many air conditioning systems, as well as heat pumps, use a dual capacitor system which connects both the start and run capacitors to the compressor and fan motors.
