Quiteoften this is due to grease or food particles stuck somewhere in thecavity of the oven or stuck on or behind the waveguide cover.

It can be fragile, andthe metal edges of the oven behind it can be sharp, so be careful!

The cover and the metalbehind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal ofthe oven is chipped or charred, it will have to be sanded smooth andclean and dried thoroughly.

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

If your waveguide coveris burned, it will need to be replaced. It provides importantprotection for the magnetron.

Hello bruton. As a microwave oven ages, the interior paint often deteriorates as does the internal part that creates the micro waves.

Using this is not a good idea as there is now a fire hazard. The best solution is to replace the microwave. There are sales now and you can get a nice new one for under $100.

Put a hamburger in to heat, on a paper plate. The interior began to spark. the plate on the Right hand side appears to have a something black and charred (as if a piece of meat or grease has adhered to it)...

Usually the sparks are from exposed metal. Clean the oven, and the table and anything else you can inside. Then just try nuking a cup of water. That gives it something to work with and it won;t make any sparks itself. Then just see if the sparks are gone. If the paint has come off inside the cavity and exposed some metal you can get sparks but that usually means replacing the microwave. If its caused by an object or buildup then a good cleaning stops it.
