Thanks a lot, djman!
I had the same/similar problem - buzzing sound when the door opened, or any cooking function was selected, plus the table did not turn. Replaced C01 (220uf 50 V) and the microwave works like new.

All I can is thank you. I purchased a capacitor online and replaced it in 10 minutes. Can't believe it completely addressed this issue.

the noise you hear is contact chatter. The capacitor and the burned 30k 1/4w resistor did the trick. Like new. This must be a defect with this model board. Can't imagine how many went into the trash b/c the board is $150 over $4.00 in parts. FANTASTIC!!!

Same issue. Microwave started making a terrible buzzing noise. After researching online, I found this thread. Suspected capacitor C01 as djman said. Ordered the part from an online from Parts-Express, bought a cheap soldering iron kit, removed the old capacitor, and soldered in the new one. VOILA, it now works!
I hope someone else finds this useful. I have never soldered anything before and I had no issues, although I read up on it and watched a few YouTube vids first.
Cheers.
