Electronically, everything appears to be working...all controls on sensor pad, lights, turntable etc. However, after 30 seconds of use, a distinct burning smell is detected from inside the unit. After a minute of use, white smoke comes out of the INSIDE grate of microwave (which is located on the right INSIDE side of the unit next to sensor pad) Coffee in mug doesn't heat up. Electrical outlet is fine. I checked it out. What do you think is the problem? Thanks

This is very similar to my problem, except that my microwave DOES heat.

This started shortly after I accidentally used a bowl in the microwave that had a bit of metallic glazing, and it caused arcing (under 5 seconds, I think). I immediately took it out and it seemed to function fine. This happened about a week ago.

The microwave is clean, and there was no burning smell before the incident. When the unit is not actively being used, there is no smell. I know I should stop using it, but in the mean time, I stand there with my hand over the button, just in case.

I'd rather repair it than replace it if possible, but I'd like to have some idea of what to expect if/when a repairperson comes over. The last time I needed to do a (refrigerator) appliance repair, I was able to buy a part from you and do it myself for a tiny fraction of the local repair estimate. I know this is not the same thing, but I don't want to be taken advantage of, like I almost was that time.

Kryan, The odor and smoke are probably due to the wires being subjected to high voltage arcing bouncing back into the system. But, it's more likely the magnetron tube (Produces the microwaves) and antennae were damaged as well, and is most likely the major cause of odor. Expect to need a new magnetron tube as well as any hi side components damaged by the arcing.
