Q: How to distinguish between starting capacitor and running capacitor?A: Under normal circumstances, single-phase motors with a capacity of less than 500W use a capacitor, and 750W or more use double capacitor. One of the two capacitor motors is the running capacitor and the other is the starting capacitor. Both capacitors are non-polar capacitors. The small capacity is the running capacitor, and...

Q: When to Replace run capacitor?A: As a general rule of thumb, a run capacitor will far outlast the same motor's start capacitor. A run cap will also fail or wear differently than a start cap, making troubleshooting slightly more involved. When a run capacitor begins to perform outside the allowable range, it is most often indicated by a dropping of the rated capacitance value (the microfarad val...

Q: My start capacitor has a resistor on it. Do I need a replacement capacitor with one?A: Most replacement start caps will not include a resistor.
