SOURCE: I have a panasonic microwave

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.

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 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.

You can order Panasonic parts here.

If that is not your issue, you can reply back with more details or I would recommend that you contact your nearest Panasonic-authorized servicer.

Why doesn't it stop running if door is shut?

It sounds as if the one of the door switches have either gone bad or need adjusting. you will need to call a service engineer as microwaves have no customer serviceable parts apart from changing the bulb. Kenmore is a Sears brand, so contact their service.

Need to replace broken door handle. Cannot get to screws inside door to release broken handle and replace with new handle.

Look for a removable insert around the inside window. If not there may be screws along the outside edges to separate the door sections. Eric
