Try replacing the screws with larger ones. Maybe you ordered the wrong piece, if your microwave comes with a mica cover (A fine, square piece of mica) and you received a plastic one, you will need to get the right piece or adapt the one you received.
You can get the mica cover on any microwave service.

This is a simple problem & solution.
Quite 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.
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.
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.
Since your waveguide cover is damaged, it will need to be replaced. It provides important protection for the magnetron.
