CAPACITORS

ELECTRICAL ITEMS AND CONTROLS ARE FACTORY TESTED AND ARE NOT RETURNABLE

All air conditioning units, heat pumps, and furnaces come with capacitors for the fan and compressor unless it is a three phase system. Three phase systems are generally commercial.

A capacitor helps the motor run or start depending on what type of capacitor it is. In brief, it provides an energy boost to get the motor started.  A start capacitor performs the function of a centrifugal switch. There is a brief pulse to start the winding taht couses the motor to rotate. The run capacitor are designed to provide a phase shift for the motor.

If a capacitor has aged from normal usage it becomes  too weak causing the motor not to run. This is not an uncommon; many A/C units require new capacitors after a few years.
