I have a 115V 1/2 HP water pump that boosts the water pressure in the house. When I flip the switch, the motor hums and does not spin. there's a tiny jerk when I flip the switch. it gets very hot and the thermal switch is then tripped. I opened the switch panel and inside is an approx. 3 inch long 1 inch diameter capacitor. It smells fried. The pump spins freely by hand so it's not siezed. I'm thinking either the motor is fried or the capacitor is fried. The whole thing is italian and i'm not having much luck locating the original capacitor. it's 250V 40uf capacitor consisting of a sealed plastic case and wire leads. Not sure if it's a start capacitor or a run capacitor. Can someone let me know which type of capacitor it would be and if that could be the problem? Thanks.
