    Looking for run capacitor source

    I have a Pentair 1HP Whisperflo main pump with a bad capacitor. I pulled the capacitor from my working water feature pump and put it in the main pump with great success. The pump appears to use an A.O. Smith motor and has a 30uF (6%) 370VAC run capacitor (oil filled). LPS doesn't carry them. The model is a CSC 628318-308. Does anyone have a good (ie - non-price gouging) online source or a Houston, TX source for motor capacitors?

    Should I upgrade capacitor to a higher farad or higher voltage model?

    Thanks, Alex

    Re: Looking for run capacitor source carries them.

    Don't change capacitance or voltage. It probably won't work if the capacitance changes, and there is no benefit to going up in voltage.

    ETA: Just checked and poolcenter is out of stock. The part number is RD-50-370

    Check local AC supply houses--these are fairly common .. You can also ways use a higher voltage cap if needed -- the uf needs to stay the same..

    Why does the uf need to stay the same? With air conditioner's you add capicatance (hard start) when they have issues starting.
