Buzzing noise, no heating of food
Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.

Appears to work, but food not heated
The high voltage tired was shorted. I replaced it with a new one, but that did not solve the problem.
You can test the high voltage tired with a voltmeter and a 9 V battery. Search Search for it on YouTube.
You can also test the high voltage capacitor, the high-voltage transformer, and the magnetron with a multi met ... Read more er. Search for the procedures on YouTube.
I tested all these high-voltage components with a low-voltage multi meter, and they all checked out OK (after replacing the diode). However the microwave still did not heat food.
When working on a microwave it is important to unplug it and also discharge the high voltage capacitor. The capacitor has a 10 megaohm resister to automatically discharge itself, but it may have failed – – so discharge it manually.
In the end I ordered a new microwave.

Microwave stopped working - would not heat up
I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.
Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those w ... Read more ere a little more complicated but still easy to do.
Now the Microwave works just like new! Cost me less than $100 for all parts.
