I followed the generic trouble shooting directions on the web site. It suggested either diode, capacitor and/or magnetron. I test each. All tested OK except diode. It was supposed to measure open in one direction and appox 200k ohms in the other direction. My diode measured open in both directions (tried multiple times, multiple settings). I replaced the diode. The order process was great and it shipped immediately. I knew I was in trouble when I measured the new diode and it too was open in both directions. It was easy to install but unfortunately no joy - did not solve the problem. At this point it is likely cheaper just to buy a new one
