SOURCE: Panasonic Microwave NN-T785SF Door switches are broken.
Oddly enough, the switch holder is called a "door hook". For this model, it is part # F3020-1200 in case that is bad.
The hook assembly that protrudes from the door is called the "door key".
If you gently push up on the door key there should be spring tension. If it just flop right up, the spring is off inside.
Normally the problem is not the spring, but a broken spring mounting tab on the door key or the inner door panel.
If it's the door panel,it's usually easier and cheaper to use epoxy and some kind of hardware to fashion a new spring mount.
The door key is easy to replace or repair if that's the issue.
Normally you have to separate the door panels (as shown in the attached photo)and then you'll see the screws you need to remove.
Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.
The best place to order parts for this brand is Tritronics. Or you can call them toll-free at 866-779-5835. Their Web site will be down until Jan. 2nd.

Not to worry ,Please use a good torch light or lamp to look inside the microwave cabin. On the side where the magnetron is fixed look for any food particles which could have stuck while heating. Use a good cleaning solvent to do this job. You must remove all the roller and plates and clean dry. Once you have done this open the top cabinet with the mains wires disconnected. Look inside the side panels for dirt, insect which have got entangled and cooked. use a good brush and blower to clean dry. If the main capacitor has leaked replace with a similar type. Get help if you are not able to do this as it is a dangeorus section with high voltage. You will get to the smelling part once you had inspected these areas. Replace the part in question, can be even the surge protector at the mains end. Hope this helps. Good day

It thinks its overheating, and the (faulty) thermal shutoff is shutting down your unit.
fix: since repair parts for household appliances are unavailable (parts are available for major
appliances only), your fix is to replace the microwave.
Or give it to the handy kid down the block who will disable the thermal shutoff and use it to
melt plastic stuff for demented puerile YouTube videos...
