Micro was working fine. After a short heat cycle I opened the door as the countdown timer reached 01 or 00. When I closed the door again something started running again. No way to turn it off. Controls all seemed to work correctly but even re-starting a heat cycle, with normal additional sounds, did not stop the noise. Turned power off and on. Same. Unit seemed hotter than normal so I unplugged and let cool. Plugged back in...no control lit. Like dead. Suggestions on cause or part to replace?
For model number PSB1200NWW01

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 mic
... Read morerowave 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.
Turned of f the circuit breaker to the microwave. Unscrewed the cover (1 screw!) popped out the old bulbs and plugged in the new ones, using the bubblewrap as a handle to be sure my skin didn't touch the light bulbs so the oil from my hands didn't damage or shorten the life of the new bulbs. Turned the circuit back on. That's it!
Unpluged power cord!! Removed front control panel to expose electronics (need to remove top horizontal vent cover to expose mounting hardware). Unplugged leads to control panel board. Removed magnetron with Tstat (3- phillip heads, need stubby). Installed new parts and control panel, plugged it in tested. Done.
