Question about In Microwave Ovens
Our microwave, a (built in cabinet with venting), will tend to shut itself down if we cook something longer than, say, 8 minutes straight. No power, lights on panel out. Then a few minutes later it powers back up and is ready to go again. We overdid the cycle by cooking another long cooking item right after it came back on, and of course it powered off again, but this time when it cooled off and power up again, it fails to heat the food. There may have been a slight odor coming from the machine as well (electrical). Clock counts down, fan running, no cooking happening, though. Any guesses about what we broke and it might be worth fixing? Unit is less than 2 years old.
Not enough venting. Imagine putting your hair dryer on full and putting it that cabinet. Would your venting keep it cool? Your microwave oven uses about the same current

I would suspect either door switches or an intermittent control circuit board, either of which can be repaired. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure over time. I have a text file on my site called "doorsw.txt" which helps in diagnosing and repairing door switch problems. You can find the file via a Google search. It will help you check and replace the door switches if you or an able friend is so inclined. In some cases, the problem is a bad connection or a bad relay on the control board. That's something we see fairly often, and we repair them for only $32.50 nationwide.

The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck

is usually caused by either a bad door switch or a loose door switch
mount, which are pretty simple problems to fix.
Even though a door switch clicks, it may still be bad inside.
Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

Ok just figured this out! It is a problem with the alignment on the lower door switch. I took the cabinet off and lifted up on the door switch slightly and voila! It works. You could probably fix this without taking it apart, just lift up on the door ever so slightly. I hope this works for you.
