Question about Magic Chef MCD1311ST Microwave Oven
That would be the waveguide cover.
If it gets food particles or grease on it, it will spark.
The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.
If the waveguide cover gets damaged, it will have to be replaced, since it provides critical protection for the magnetron.

the microwave is sparking or arcing the waveguide cover might be
damaged and shorting out. Try removing the waveguide cover and see
if the problem goes away. If there are any damaged spots in the
microwave ceiling or sidewalls, repair them and paint them with
microwave oven paint. Replace the waveguide cover if it is burnt or
if it will not stay in place.
the microwave is sparking or arcing near one of the rack supports,
remove the support, repaint any bare metal, install a new support.
