dryer would not tumble and would trip the thermal overload protection

I disassembled the dryer as described in many of the other repair stories. One tip that I would like to share is to test the motor prior to assembly. I did this by removing the idler pulley and getting the drive belt clear of the motor pulley. Unfortunately I had already disassembled the top and front of the dryer so I had to jumper the door switch to test the motor. If you do it in this manner be very careful to ensure no wiring is shorted or going straight to ground. I found that my motor was shot and replaced it at the same time as doing the other repairs. I used a small magnet to hold the grounding ball in place while replacing the drum bearing, this worked very well and I was able to quickly assemble the parts without an "extra set of hands."
