Hi All,
I got a problem with a microwave 
So was heating up a food… worked for like 30 seconds… and then I heard lound buzzing sound… and it went dark. no power or anything to it.
Started troubleshooting and looked behind the keypad/display and I found there were two fuses, tested and the one on a right was bad. got the new one… inserted… powered it on… and front panel lighted up again… set a clock… and now I clicked the START to test… well… it started… 1-2 seconds in I hear this loud buzzzz and then pop again…, opened the panel again… tested the fuse and it went bad (so looks like some component is causing it, and fuse basically protects rest of the equipment, so now I wonder what is the next thing I can test and how to find out which component is failing.
Here is the picture of the fuse I was replaced and that got bad again:
Here are some more pictures:
