The display of the control worked, so one might not question it but there is nothing else that would simply shutdown while heating. This part came faster than a 'technician' and 5 sheet metal screws and 4 mounting screws later, the new unit was installed. The only delay was the waiting for the oven to reach full temp to verify that it was working - it is.
The parts places try to sell a new membrane panel ( adhered display cover (numbers and labels) for these but the old one can be removed and reused just fine.
