Glad you got it sorted Randy. They do some times buzz or whine, but the next thing that happens is usually a loud bang followed by a snow shower of waxed paper and aluminium foil, so I would not recommend listening with a stethoscope if it IS the capacitor making a noise! Seriously, you have illustrated an important point for all here in that a start or run capacitor can go bad gradually, and cause noise and reduced motor efficiency when it does.
