Question about Sharp R-408J Microwave Oven
often this is due to grease or food particles stuck somewhere in the
cavity of the oven or stuck on or behind the waveguide cover.
It may also be in the area of the turntable support, coupler, or motor.
The waveguide cover (also called a spatter shield) is usually about the size of a playing card and often held in place by a plastic rivet.
In some models it is a larger stirrer cover type made of thicker plastic in the ceiling of the oven.
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 is damaged, the area will first have to be sanded smooth and cleaned 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 critical protection for the magnetron.
