Most mass produced electronics are assembled by machines and they use water soluble flux. A run capacitor is designed to keep a motor running smoothly by providing the right amount of voltage to the winding coils. All of those items are a bad influence on impressionable caps, and can make them go bad. My tried and tested method of putting capacitors on trial are as follows: Connect both leads to the L/N of a mains plug, turn it on and see what happens; if the capacitor explodes spectacularly, then it was a capacitor of pure heart, if it doesn't explode, then it is an evil capacitor. Not all caps are created equally. November 30th, 2022. How do I stop my portable AC from tripping the breaker? How do you know if a capacitor is working? A capacitor is an important part of a fan motor. Run capacitors are designed for continuous duty, and are energized the entire time the motor is running.
