I think that this Craftsman table saw is a piece of crap, model number 137.218240. The motor can pull wood chips into the table saw motor, seems like a bad design. But that was not the problem.
I decided to check the power switch. When I opened the switch cover it had sawdust in it. The last picture shows sawdust in the wire terminals. I took them all off and cleaned it out than everything was fine. Terribly bad design.
