Hi all. I have a Jet 16/32 plus drum sander which I hadn't used for about a year. Decided to give it a good clean up and when I turned on the conveyor belt it didn't move although I could hear the motor. Giving the belt a slight push it started and cleaning was started. However after about 3 revolutions the belt stopped and hasn't worked since. Then sanding drum continues to work. Have removed the conveyor motor to inspect and to my relatively inexperienced eye all seems ok, no obvious wiring disconnections or damage to the circuit board. Has anyone had a similar experience or have any ideas as to how I may remedy this? Many thanks.
