Went to make some popcorn and the microwave failed to heat. There was no arcing sound, nor burning smell. I tried it at 50% power, you could hear the power supply change tone as if the maggie were turning on, but still no heat.
Did a search and found some very useful tips. I opened it and found a technical tip sheet. I shorted the the Hi voltage circuit and didn't get any spark. I got to the point of checking the Hi voltage diode, and it checks open. Used a 9V battery and looked for a voltage drop as per the tech sheet. I have a 500 VDC Megger, but hesitate to use it. My question is what would cause the diode to open? Is this common? Is it worth repairing, it's only 2 1/2 yrs old? My line voltage is 128 or so depending on what I'm running.
Thanks in advance
