I have the same problem. Dryer works as normal but without any heat. There are three thermal switches - two at the back and one in the door - these check out ok on my machine. The heating elements are fine. I suspect that I need a new timer. I have held back because I have a coprecci timer but could only find an invensys timer spare.
Does anyone know how easy it is to swap between the two makes?
