Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

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

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

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

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

If your waveguide cover is burned, it will need to be replaced. It provides important protection for the magnetron.

We have the service manuals for this model and have uploaded them to our site here and here to help you. You will need the free Adobe Reader to view or print them.

The best place to order Sharp parts is Tritronics.

Are you talking about the light inside the microwave? The front vent I think will allow you to get to the bulb. Should be a couple of small scrrews holding the vent cover on, remove them take vent off. Start it up again and see if the light bulb wiring or socket is arcing
