That would be just a defective secondary interlock (bottom door switch) or its mount.

My help file on door switches is here.

The service manuals you need are here and here.

Most likely door switches. Companies these days use switches with small 3/16 terminals and they tend to get hot and make the switch go bad. When I replace them I put in a 20 amp rated switch with 1/4 inch terminals, and a short section of better wire to the switch. If you make better connections it stops the wires from getting hot and the switch will last a long time.

i believe you would have to take the entire microwave caseing off to access the back of the plug

One or two of the door switches has failed, replacement only option, consider price.

Usually, power for the turntable motor and the magnetron tube (the microwave source) are controlled by a couple of things. One is a relay on the control circuit board, and the other is a switch that's operated by one of the door latches. It's possible the control board has gone bad or bad connections have developed. It's also possible the door switch has failed or is out of adjustment and the oven thinks the door isn't closed.

Diagnosing this kind of trouble may require working on the oven while it's operating. MICROWAVE OVENS USE HAZARDOUS VOLTAGES WHICH CAN KILL YOU. You might want to leave the repair to a professional because of safety concerns. Unless the circuit board requires replacement, it's probably worth having this repaired. Unlike some repairs, this one won't cost as much as a new oven.

Yes, I know you probably already got rid of the microwave oven but maybe this can help others. I had the exact same problem, it turned out one of the door switches desoldered itself from the PCB, leaving an ugly black PCB.

All I needed to do is remove the dirty residu by wiping and polishing with a simple pencil eraser and drill away the burned part of the PCB and resolder the switch using a piece of wire to the right PCB track. The switches probably are ready for repleacement and I did notice the relay on the other PCB also looked bad (Ormon G2R-1A-E 12VDC) you might wan to replace that.

All in all it is wise to look for something new.
If you want to fix it, also have a look at the vents on the underside just behind the controls. There is a big chance these are clogged.

You didn't mention your model number. If I knew that, I could check to see if it's one of the models subject to a recall for failed membrane keypads.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Asbestos comes from the ground, it could be all around you.

The only time you should freak is if you where to take it and break it up
and sniff it. Most people who only worked with it for years have problems. That is because the fibers cut the lining in the lungs.

So if it is in you mic, it will never cause you harm unless you rip it apart
and start inhaling everything that was inside it.

So don't inhale your microwave, and you'll be ok.
