    Would you agree that power surges (from electrical storms and power kicking on and off repeatedly) can also blow a capacitor?

    I believe power surges can damage caps, if they're already under a load.

    Yes. My most recent failed run cap was associated by the store manager with a power outage, and when the power came back on, one AC unit did not.

    It had a packard cap.

Can a 370vac be replaced with 440vac? is the capacitor doing work the whole time the unit is on or is it out of circuit after the start windings are done? Any info would be great and thanks in advance!
    Just thinking out loud here, but how to you test them to know if they are even bad on your "Moneymaker calls as i often call them.lol "

    Careful might see you on the local news during a sting,
