My daewo microwave oven Kor 860A start button doesn't work or function.

What you call all functions, I think it's only the front, the keys and the display. I think the main fuse or circuit breaker has tripped. Because when the magnetron does not work nothing will become warm.
microwave ovens should not be opened by normal users. The voltage used to get the magnetron fire is very high and can kill you when you touch it. To reach this voltage, there are capacitors inside, that can hold this voltage for a long time. So even with no power cable attached inside can be dangerous voltages. Please don't try to do this yourself. If you want it repaired visit a repair centre, but opening and replacing the defective parts can cost more than a complete new microwave. So first ask what it could cost you if you bring it in for repairs. And check what a new one will set you back.

If it's under warranty, contact the

which fuse are we talking about

It is bad for the oven to run it empty, is there something where sparks were and try it with a cup of water.

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.
