Check the internal fuse. Unplug it, unscrew and take off the cover, the fuse should be easily found in the back by the power cord. I tlooks like a regular fuse but is white instead of clear glass because microwave fuses are special. You'll have to measure it with a meter as a result and be sure to replace it with the same kind. (try finding them at radio shack) Hopefully there isn't something more serious also.

The problem that you are having is that the magnetron inside the microwave is shorting out to ground and it will find the shortest path to reach whatever has metal in it. Replacing the magnetron will solve your problem altogether and you need not do anything else different and continue using your metal racks.

Chances are that the thermostat / thermal cutout / T.C.O. (whichever it uses) has opened.
This can happen when the magnetron overheats, either due to it's failing, or if the internal cooling fan is not working.
It may also that be the 15- or 20A ceramic line fuse or the oven cavity thermostat / thermal cutout / T.C.O. (whichever it uses) has opened.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
You should be able to get the fuse from a home center or local appliance parts store.
Accessing some components for testing and possible replacement will require you to remove the oven from the wall.
If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

SOURCE: microwave not working
Magnetron may have died or internal fuse may have blown.Its could be all sorts of things.
May be time to buy a new one!
DO NOT TAKE OFF THE COVER YOUR SELVES, AS THEY MAY BE ELETRIC CHARGE STILL PRESANT EVEN WITH THE PLUG DISSCONNECTED

Testimonial: "Quite helpful; all I have to do now is translate the two solutions into french to ask them to check. Buying electrical in France is very expensive."
