I think it might be a good idea to consider having the appliance replaced, the unit is a fire hazard and judging by the burning smell it is on the way out.
Is the smell ionized (the outside smell of a cold winter morning air) or more of an electronic component burning??? if it's more of an ionized smell it could be normal, (if the smell is strong) it could be a leaking high voltage cable (electric arching) bad insulator, if it's more of an electronic component burning smell, it could be a overheating component, in both cases you should have it checked by a professional technician...
You have burned micro switches in the door safety interlock system. I have answered this question dozens of times here - i am surprised this answer didnt come up when you searched your problem.
There are two reasons for the heat to not come on when everything else works ... three actually, the third is expensive.
1) the capacitor has failed - dont try to service this unless and until you understand the dangers associated with this repair.
2) burned safety door switches
3) failed magnatron (they rarely fail)
remove the cover - find the door switch. Test them. With the door closed, the switches should read closed. If they read open (because they are burned because you open the door when the oven is operating) the oven doesn't know the door is closed so it will not turn the mangatron on - no magnatron - no heat.
I hope this informaation helps you ...

the insulation of the wiring has detiorated and with temperatue rising it further deteriorates. thus increasing the current consumption and blowing the fuse
After snubbing the darned thing overnight, plug it back it to see if it has recovered.
These things do have primitive computers and we all know how reliable those things are-
It may just have 'crashed,' just like seemingly all others.
The fuse will not be on the circuit board.Try looking around where the door switches are, or back around the fan area.If you still can't find it, trace from the powercord coming in and follow were both wires go.
