Does it have a turn table that spins your food container? If so, does it turn? If not, you are getting a solid directed beam of microwaves focused on one part of your food leaving the rest of it ignored. If it doesn't have a turn table, it will have a wave spreader inside which is nothing more than an aluminum fan that is sometimes driven by a small motor and rubber belt. You won't see this as it is inside the chamber that contains the magnetron that generates the microwaves. These belts can break allowing a solid, focused microwave beam to shine on your food rather than be distributed around the oven, again, leaving the rest unwarmed. If this is the case, using the oven can damage it over time. If you don't know what you are doing, DO NOT try to repair it yourself!!! If you don't get the outer casing back together properly, you can expose yourself and / or your family to dangerous amounts of microwave radiation. You should take it to a qualified service center for repair but I would venture a guess that it is already damaged because of your statement "but getting increasingly unreliable". Even if it isn't damaged, it will probably cost you more in labor to fix it than it would cost to replace it. Good luck.

FIRST YOU CAN CHECK THE HIGH VOLTAGE AND HIGH VOLTAGE FUSE (IF THERE) and high voltage diode, capacitor, wiring of magnetron , finally high voltage is there may be magnetron, and check the filament wiring...
SOURCE: will not heat on one touch mode but will heat on convection made
your microwave magnetron part is probably broken you need to send this to a shop im afraid, might cost you 40- 60 $
cheers
SOURCE: daewoo kor-861h, electrical smell and will not heat.
Turn if off, and leave it alone, remove it, if you can remove the unit, take it in for service, something is wrong if you smell electrical, most people for some reason can smell and identify correctly electrical or at least insulation burning smells, which means something is burning internally, not safe, fire hazard, unit needs to be repaired by qualified technician or replaced with new unit, take no chances, nothing you can do to repair this, could be a shorting transformer, or shorting power cables, but to attempt to trouble shoot this with email is a long shot, and depends on your experience expertize and testing equipment.
I wish I could give you a short easy answer, but the hazard and your safety is more important than a microwave.
