I just replaced the start capacitor on my pump motor (AO Smith C48L2N134O2). The motor was humming, but not starting. The capacitor tested bad. New capacitor started it up with no delay. The motor ran for a couple of hours and turned itself off - it is thermally protected. When I realized it, I felt the motor and it was very hot to the touch. Took the cover off again, to find one of the yellow wires that connects the capacitor to the motor burnt nearly into. Anybody experienced this before? Thanks.
