Air Conditioning Capacitor: What It Is And How It Works



The Capacitor is a part of the electrical part of the air conditioner. It serves to store electrical charges inside it. This avoids overloading the device that could damage it.

This piece can give you a lot of headaches, but don’t panic. For the well-prepared technician or licensed contractors, it is no beast with seven heads.

What Is An Air Conditioning Capacitor, And How Does It Work?

Capacitor and Air Conditioning

Air conditioning is not the only device that uses the Capacitor. Any electronics can have a capacitor inside. TVs, refrigerators, washing machines and, of course, computers.

Where Does The Capacitor Enter The Air Conditioner?

When talking about an air conditioning capacitor, we are talking about a large piece in the condensation part of the device. It is like a shield for the most important parts of the device. It is between the electric current inlet and the air conditioning fan and compressor.

How It Works?

The electric current that comes from the outlet enters the air conditioner. Then it is sent directly to the Capacitor. And as we explained at the beginning, the function of this piece is to store electrical charges. What the Capacitor does is filter the electrical energy that enters from one side. This electricity is not always constant, so it does the filtering. It keeps what is excess and releases only the electric current necessary for the compressor’s operation and the fan.

Works As A Filter

The current that enters the air conditioner is alternating; it can change the power more or less. The Capacitor receives this current, stores what is left, and lets out a constant current that does not fluctuate on the other side.

This avoids electrical overloads on the compressor and the fan. It also protects these parts from working with a lower current.

Make the switch.

How To Change The Air Conditioning Capacitor?

To change this part of the air conditioner is very simple. After the technician proves that the Capacitor has broken, buy a new one, open the condenser, disengage the old one and engage the new one.

Of course, all of this must be done with due care. The device must be disconnected from the electrical power, and the technician must use all the equipment for protection against accidental electrical discharges.

If everything is in order and for quality air, open the condenser cover and change without mystery. You don’t have to move the device or walk.
