While that may very well be what's going on, I suggest giving the motor a few 'hits' with either a 2X4 or the butt end of a hammer's handle, while the pump is running - there is always the chance that the starter switch is just a little rusted (though, this can also be caused by shaft seal failure). Poconos knows this better than I, he may have some better advice. If the 2X4 advice works, there are ways to clean the slightly corroded connections If this doesn't work - open the back of the motor and try to turn the shaft with a screwdriver, if it's only slightly seized, it should turn for you ~fairly easily.

The problem may just be moisture getting into the unit over the past 4 years and causing slight corrosion, which can be dealt with by doing what I said. If all else fails, a new motor is in order -- should you find that you need a new motor, we, here, can 'walk' you through the replacement.

I sincerely hope that you can fix this without having to replace the motor! If you need any other help with this, we'll be here!!
