This is what I know: the charging of a capacitor from a dc source happens instantaneously. Since there is no series resistor to limit the current, then what actually prevents the current to become infinite and burn the capacitor at charging time? On the opposite is the discharging. If a charged capacitor is shorted, it will burn.

Top Cause of Single-Phase Motor Malfunctions | Fluke
Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost always replaced.
