Here a link to some images I took of the motor repair. I placed a very fine jumper wire over the thermister and problem is solved completely. I tried just cleaning the motor first, but did not solve the problem, but after modification of the thermister WOW! works Great! I used a single strand from soem very thin speaker wire to form the jumper (kind of like a fuse) so should the button ever be held down for a long period of time, this is now the weak point in the circuit and shoudl fail first...but I did not test it to be sure.
