I know you say you checked all the switches and connections, but it sounds like a defect in the control mechanism. A defective microswitch, failure of one of the safety switches etc. Don't try to fix it yourself though as there are safety issues involved (high voltage and radiation) - get a repairman! Considering the low cost of new microwaves plus radiation concerns, you might also want to think about getting a new one.

I still suspect a bad door switch or door switch mount, but it may be a stuck relay or bad conneciton on thew control board.
We have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Hey, actually did some playin around with door and lifting it and believe it or not-slamming it several times, and each time it done the problem, then all of a sudden the light went out, and I could push the start (one minute instant button) and it worked...so I guess it would be the sagging of the door, and its actual fit when shut regular...I know it sounds like its not fixed, and it will more than likely eventually stop working, but, my thoughts are I could slam it to death and get out of it what its worth, or have to buy another one anyway....I know this isnt a fix, but I personally couldnt take it apart to tighten the door, maybe I will mess with it some more....Good Luck sorry its not a fix....Sandra
SOURCE: Where is my fuse
Usually on the
floor of the oven behind the control panel or between the door switches.
If
the fuse is good, it may be an open thermostat or thermal cutout (TCO)
/ thermal fuse on or near the magnetron or on top of the cavity / body
of the oven.
If it goes dead for a while during or after cooking
then comes back on, the magnetron is probably overheating and causing
the magnetron thermostat to open.
Then when it cools, it closes the circuit and allows power through again.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If
it goes dead or blows the breaker (or GFI) when you plug it in or open or close
the door, then there's a problem with a door switch or door switch
mount.
If it's intermittent or random, it may be a bad
connection, usually on the control board or a loose fuse holder, or
even an intermittent fuse.
You should do a continuity test on
the fuse while it's in the holder (with the microwave unplugged, of
course) then turn the fuse by hand or take it out and put it back in,
then test it again.
If you remove the fuse, then press the meter
leads against the ends, it can allow internal contact to be made and
make a bad fuse appear to be good.
If you or someone you know
decide to look into it, we have critical safety information and
disassembly information at our site, and our link is at our listing here on FixYa.
