Help from Microwave tech please.
2002 motorhome, presume the Sharp micro convection oven is the same age. There is 100,000 miles on the coach, we use the oven a lot. Recently, when reheating tea, or melting cheese on toast, power ...

The microwave power circuit consists of four major components: The magnetron, a high voltage diode, a high voltage capacitor and a transformer. Any one of those four components could be the problem. If the diode is bad, there won't be any heat. Ditto for the capacitor and transformer. Magnetrons are generally reliable. I would take the above advice and examine the remaining components to see if there is any sign of dirt or arcing, particularly around electrical connections. Look closely at the capacitor as it has a metal case that is grounded.
