Turned out the issue was easily solved by replacing a single, inexpensive fuse.
First off, UNPLUG THE MICROWAVE.
The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the microwave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.
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
