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.

Please write back with your brand and model number if you need further help.

Why did it catch on fire?


Any flaws in the painted surface on the inside of the unit will cause a spark and that generates heat. Examine the surfacecor any exposed metal. You have to use special paint to resurface the inside.

dont use the microwave until you retrieve what dropped inside when you removed the port. The grinding is most likely a foreign object that is hitting the moving parts of the microwave and causing sparking. It can catch fire

My emerson microwave #mw8999rd shoots out fire from a silver piece of cardboard thats on the righthand inside of my microwave oven. whats with that?


There is electrical problem in your microwave heating circuit. This is a fire hazard and you should stop using this microwave and unplug from the outlet. This is not something you can fix and the fuse does not protect your system anymore. The best choice is to purchase a new one and throw this away.

It catches on fire, through the center turn table.


NOTHING in a microwave should ever be on fire. Depending on the damged cause by even a small fire, the repair may be involved and costly. Inspect stirrer motor by removing bottom of microwave with power off. Note damage and replace stirrer motor and wiring harness as needed along with turn table drive block. Check to make sure all connections with all wires are sound with no exposed copper wires or shorts of any kind. Test always using a cup or bowl of water.

Roper microwave caught a paper towel on fire.


Why is this even a question?

Of course a paper towel can get hot enough to catch fire in a microwave. In addition, anything not specifically identified as microwave safe can melt, deform, crack, chip, spark, catch fire, explode, etc...
This is not a microwave problem.
