Went to turn on the filter and the pump is just humming. It will hum for 30 seconds or so and then I have to reset the breakers (although they aren't thrown) to get it to hum again. Read on here that it is probably a bad capacitor. With power off, Took the filter basket out and couldn't reach the impeller. Took the back off and the shaft turns easily, but there is no slot for a flat head screw driver to turn it. I turned it by hand a few times and tried turning on the power but it still just hums. Took the capacitor out and will try to find a replacement tomorrow. I read somewhere that some motors have a run and a start capacitor. There only seems to be one cover on my motor and I only see this one capacitor in the end. It is 25MFD, 370 volts. Is that the start capacitor?
