The two windings are displaced 90 degrees in space. Types of air compressor capacitors. So, if the relay fails, the compressor may overload with power or click on and off.
Start capacitors increase motor starting torque and allow a motor to be cycled on and off rapidly. Motor start capacitors are used during the motor startup phase and are disconnected from the circuit once the rotor reaches a predetermined speed, which is usually about 75% of the maximum speed for that motor type. On the side of the capacitor, there should be a label.
In this image the capacitor voltage is 250v ac, meaning 250 volts and an alternating current type capacitor. They should never be wired directly across a line and should instead be used for startup/run purposes only. Start capacitors are not designed to dissipate the heat associated with continuous operation;
A compressor can cost anywhere from $1,200 to $2,500 to replace, whereas it typically costs less than $400 to install a hard start kit. The start relay/capacitor keeps the compressor from an overload of power. The capacitor is an important part of the air conditioner, as it helps to store electrical energy that can be used to power the unit’s components.
To check the capacitor you need a volt meter/ohm meter. Start capacitors possess a very large capacitance value for their size and voltage rating. If your compressor motor also has a run capacitor, that one helps to keep the motor running.
When the compressor won’t start or starts to overheat, be sure to check its check valve. These capacitors usually have capacitance values of over 70 µf. When disassembling, unplug the connecting wire and use a screwdriver to remove the fixing screw of the snap ring.
