if your brushes and the wires to the motor are ok then it sounds a bit like a board problem
as a long shot have you tried a different socket as they can go faulty and tend to go off during heating cycles

Oh thanks for that Dave .. PCB problem was my other thought but I look at a board and I don’t really know what I am looking at or for … so it might be replace it and junk the old one Ken says they are not available and expensive ….When you say different socket do you mean plug the beast in somewhere else ? worth a try I guess ….
