I took the advice of another buyer and replaced the magnetron, capacitor, and diode from my microwave (make sure you discharge the capacitor). It was not a problem at all to do, I did find an excellent video on YouTube on how to test all of these components and almost anything else in a microwave. It’s called Microwave Oven Troubleshooting in Minutes- Step by Step by electronicsNmore. It was the best thing I watched. Turns out my magnetron was the only thing that was bad and it’s the most expensive part, so replacing the other too wasn’t a big deal. My microwave really heats well now. I guess it had been getting bad for a while. I might get add, my microwave was a $1500 GE MONOGRAM microwave/convection oven so spending a couple hundred for parts was a no-brainer, but had it been a cheaper $300-400 model, I would’ve just bought another one. Matching the appliances in my wife’s kitchen was also key. I might also say, that although I’m handy and do have some electronics experience, I built my own tube guitar amps years ago, I am a counselor by trade, and doing this project taught me how a microwave works. It was fun to learn, and easy to do. Watch the YouTube video before you remove one screw. You will learn a lot, and also see a professional be extremely careful while discharging the capacitor. 1000 volts is nothing to play around with, but the capacitor does have a discharge resistor built-in and mine was discharged when I tested it, and although the video shows you how to build a discharge rig using a ceramic resistor, which is the safest way to go, I don’t personally think it’s necessary. He shows other ways to discharge too. This is the most important thing to do in this repair.
