Perfect Run Capicator for Pool pump
Worked great on my Super Hayward 1 HP pool pump. The original run capacitor is rated 50-400 uf. I read up a little and understood that original run capicator when burns out, makes a humming sound but impeller freely rotates when manually spun around. It may help others to know that you are good to go up a notch on microfarad but not down. I ordered the Upgraded Version 340-408 uf 110-125VAC BlueStar capicator. It was easy to install (I took one wire off at a time from old capacitor to make sure all three are similarly placed). BlueStar capacitor was perfectly sized. It seemed to have a better physical construct quality than the original. Btw I am not a super handy kind of guy but this was easy. Run capacitor is only two outside screws and one inside screw away on an Hayward super pump 1HP (gold). This cost me a little research and 13 bucks, replacement took me 10 minutes max —- saving me hundreds in service/ replacement costs! Few days in, it is going strong. Easy, fast reliable start. Would definitely recommend!!

Perfect fit and fixed my issue
Fixed the problem on my lift. Just be sure the number on your old one exactly matches the new one. And check measurements. Price was a fraction of the cost anywhere else! Other than that I am very pleased and back to lifting cars on the rack!

Worked well on 3/4hp pump motor
Water pump works again. Thanks BlueStars. About 0.130 longer than my original, so rear case was a difficult fit. But that's my fault for eyeballing the length instead of measuring. So if fit is critical, measure better than I did. But this cap works great.

It’s working for a week no problem, I measured the capacity it was 321uf and the size was fit to original position . I give four stars because I used it for air condition starter and it doesn’t have the discharge resistor , I installed a resistor.
