When replacing the capacitor on a PSC motor, use only replacement capacitors with the same manufacturer rating.
Using a lower rating would result in a weaker motor, lower rpm, lower starting torque, lower efficiency, and a higher current draw. Using a higher rating would result in an increase in the starting torque, an increased rpm, a lower current draw, lower efficiency, and an increase in winding temperature.
Always maintain the capacitor nameplate-rated voltage or higher (for example, replace 370 VAC with 440 VAC at the same microfarad rating). This will ensure efficient and effective performance from a motor.
