A typical start capacitor rating ranges from 25 µF up to 1,400 µF and 110 Vac to 330 Vac. Because the fan motor is one of the hardest working parts on an air conditioner, it is subjected to a lot of wear and tear that can lead to frequent repairs or replacement. It means that your AC capacitor needs a lot more energy to get the job done. Compressor Motor Run Capacitor: Here is the most popular capacitor that fails. They’re 2 in 1, two capacitors in one.

If the capacitor has failed the symptom is that the motor won't start. It gives the motor an initial “push” on start-up, briefly increasing its starting torque and allowing the motor to be cycled on and off quickly. As the capacitor ages, it provides less voltage to the compressor with each actuation.
