Could it be "finger trouble"?
A magnetron will fail within seconds if no food/liquid is placed in the oven cavity as there is no where for the energy to be dissipated and it will "cook" itself.
Is the high voltage supply and diode pack OK?

This is not good. Get the unit serviced by a professional before you use it again.

Since the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

If it is not repaired, the rust will worsen until the cavity is damaged beyond repair.

That's usually a bad magnetron. This one has a 5-year warranty on the magnetron, so you should only have to pay for labor to get it replaced. I would call Maytag at 800-688-1120.

You have to remove the outer case but you should be aware that you are exposing yourself to dangerous, even lethal high voltage inside.
