How to connect the starting capacitor of the air conditioner compressor

In general, our air conditioners have single-phase electricity and three-phase electricity. For single-phase electricity, there are three capacitors, that is, the internal fan capacitor, the external fan capacitor and the compressor capacitor. For three-phase electricity, there are only two capacitors, which are the internal capacitor and the external capacitor. Because the three-phase compressor does not use capacitors.Many users may have such doubts. For the capacitor of the air conditioner, how much is the price if you replace it or find a master to repair and replace it? In addition, the editor will introduce some capacitor connection methods for the starting capacitor of the air conditioner compressor, hoping to be helpful to everyone.

一、How much is the price of the starting capacitor of the air conditioner?

Generally, the price of capacitors for fans is a few yuan, and those with better quality are about tens of yuan. They are available in electronic markets and places that sell home appliance accessories. The price of replacing the capacitor by yourself does not exceed 50 yuan. However, if you are looking for a maintenance person to replace it, you have to pay a certain maintenance fee. The door-to-door replacement by the master usually ranges from 100 to 200 yuan. (The price comes from the Internet, for reference only)

二、How to connect the starting capacitor of the air conditioner compressor?

(一) If the wires of the compressor are red, yellow and black

1. Insert the plug of the red line into the capacitor of the compressor and connect it with the red wire to the plug of the male end;

2. The yellow line is connected to the other part of the capacitor;

3. As for the black wire, it is directly connected to the second blade from the left on the terminal board (that is, the fan motor connected to the second and black wires you mentioned is the same port).

(二) If the wire of the compressor is blue, yellow and brown

1. Insert the plug of the blue line into the capacitor of the compressor and connect it with the red wire to the plug of the male end;

2. The yellow line is connected to the other part of the capacitor;

3. As for the brown wire, it is directly connected to the second plug from the left on the terminal board (that is, the fan motor connected to the second and black wires you mentioned is the same port).

(三) Other types

The external unit of the air conditioner is two capacitors and two motors, the two motors of the compressor and the external fan! There are three connectors coming out of the motor. These three connectors are the common winding, the main winding, and the auxiliary winding. The 220V mains is connected to the main winding of the common winding, and a capacitor is connected between the main and auxiliary windings.How to distinguish these three windings. You can measure it with a multimeter in the ohm range. The resistance value is between the main winding and the auxiliary winding, so it can be judged that the other end is the common end;After the common terminal is determined, it is easy to judge the main winding and the secondary winding. The main winding has a small resistance to the common terminal, and the secondary winding has a large resistance to the common terminal.

The above is the relevant introduction about the starting capacitor of the air conditioner. The editor mainly introduces the relevant price of the starting capacitor, and introduces some corresponding connection methods for the starting capacitor of the air conditioner compressor in three situations. I believe that after reading it, you will have a deeper understanding of this aspect.
