The CR38K6-PFV-220 typically requires a run capacitor with a rating of 30 µF to 35 µF and a voltage of at least 370V. It's essential to check the manufacturer's specifications for your specific model to ensure compatibility. Always verify the capacitor's size and rating before replacement to maintain optimal performance.
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.
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.
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.

No
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.
If you mean run capacitor, as in the run capacitor for an AC motor, it is usually a round or oval cylinder.
For a 1-ton compressor, you typically need a capacitor rated between 30 to 40 microfarads (µF) for the start capacitor and around 5 to 15 µF for the run capacitor, depending on the specific model and manufacturer. It's important to consult the compressor’s specifications or user manual for the exact capacitor size required. Always ensure that the voltage rating of the capacitor is sufficient for your application, generally around 370 volts or higher for HVAC systems.

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.
true
A run capacitor is used to improve the efficiency and power factor of a single-phase motor by providing a phase shift to the auxiliary winding. Once the motor is running, the capacitor helps maintain a steady motor speed and performance. It remains in the circuit to assist in the motor's operation.
