Just got the repair manual, many thanks fellow appliantologist. And following troubleshooting guide.

This is what the microwave was doing before the death. It burned out the door safety switch, and I do mean burned to a crisp, like either it was being way overamped or was being exposed to microwaves leaking past the microwave shield it sits next to.

So, I would put in a switch and then a week later it was burned up too. This went on about 5 times.

Now, even with a replacement switch, just plain dead.

Also, When I go from L2 to Neutral as the troubleshooting guide recommends, I don't get 24 ish ohms, but 240 ohms. I double checked.

Any Ideas?

I have a feeling this is a common issue from all the assocfiated message traffic.

... from L2 to Neutral as the troubleshooting guide recommends, I don't get 24 ish ohms, but 240 ohms.
... I would put in a switch and then a week later it was burned up too.

1) (are you sure you're on L2) ?
If the (in series) Fuse, and the (2) Thermal Cut-Offs (TCOs) are good,
It's trying to measure the OHMs of the Primary winding of the Low Voltage Transformer (LVT)

2) did you replace all (3) Door Switches and the Door Switch Holder ? (cracked ?)
If the (3) Switches don't operate correctly and at the correct time and sequence,
it's designed to blow the Fuse (and possibly blow one or more of the Switches)

Thanks for reply.

Advantium became UNDEAD when I replaced the thermal cutoff fuse at bottom center behind control panel. It was completely open. See the cool Ninja quality photos I posted of the solution. Hope they are hopeful to many.

BUT, do you have any idea why the door safety cutoff switch was being burned LITERALLY to a crisp?? Havent figured that one out yet.

Could it be the big capacitor?? What should the capacitor test out to??

Opening the door while cooking without hitting stop or cancel first...
We, the unwilling, led by the unknowing, are doing the impossible for the ungrateful. We have done so much, for so long, with so little, we are now qualified to do anything with nothing.
