Want this question answered?
The run capacitor is used when the load is functional while the start capacitor is used to produce the initial torque to drive the load.
There are two ways to read this: you have a burned-out run capacitor on your motor and a good start capacitor in your parts box, and you have a burned-out start capacitor and a good run capacitor. If the run capacitor's bad and you want to put the higher-voltage start cap in its place, the answer is yes. This is called derating, and the only thing it does for you is increases the lifespan of the capacitor because you're not working it as hard as it can take. If the start capacitor's bad, don't do this--they used a 440-volt capacitor in there for a reason.
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
If the air conditioner has both, the run capacitor is likely the largest one. The start capacitor will only be in the circuit for a very short time, so overheating doesn't become an issue. The run capacitor must be sized for continual use.
A run capacitor is constructed with wire, wire strippers, cling wrap, scissors, aluminum foil, and cellophane tape. A run capacitor is defined as a unit that stores energy electrostatically in an electric field.

Because from the capacitor characteristics at first it will charge and then it will stsrt to run so when the motor get power from single phase capacitor take time for charging. Amit.
No

If you mean run capacitor, as in the run capacitor for an AC motor, it is usually a round or oval cylinder.

The capacitor size of a Rheem A/C model RAKA-042JAS is height 2 1/8 inches, width 2 3/16 inches, and depth 1 5/16 inches. As of 2013, the price of a Rheem A/C run capacitor is $11.87, plus tax and shipping.

Easier to start up. Running remains the same unless it is equipped with a run capacitor too. A run capacitor uses a little less current during run and probably runs a little cooler too.
