I have one just like it, and the best part is that I just leave the timer wheel set to max, and turn the microwave off by opening doors. I keep the doors just barely open all the time, woth benefit of it starting the moment I close the doors after putting a plate in. The only button I ever pressed on it is to open doors (mechanical), and once in a while I turn the timer to max (when I notice).
