Question about Daewoo KOR-860A Microwave Oven
In our trave trailer, hasn't been used much. has a strange smell and makes a noicse when running, no 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.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
SAFETY IS PARAMOUNT
This is a job for a professional but if
you are safety clued up, here's instruction.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
