|It is recommended that replacement capacitors be of the same MFD and voltage rating as the original. If the exact replacement is not available, it is recommended to use one with a MFD rating not more than 10% greater. Using one with a larger value could make the motor run hot and loose torque. The voltage rating should also vary only on the high side. In some cases, it will be necessary to go beyond 10%. Example, if a 370 volt unit is not available, the next rating is 440 volt.
