One thing to check if your motor dies or hums and won't spin up is the starter capacitors. The cheap and easy solution I used was to remove power from my machine. Took the caps out of the motor being careful not to touch both contacts at the same time or shorting them out before I removed them. Checked the sizes and marked the wires. My other motor worked so I switched the caps to see if that was the problem. Reconnected the "bad" motor with the known good capacitors. It then worked fine, so I found similar (though they weren't exactly the same) sized caps from surplus and replaced them with new caps. Similar meant similar capacitance, similar size, and similar type.
