Problem for Thermador MBBS 1100 Watts Microwave Oven

Sparks aplenty!




By dan121212 on Jan 05, 2009

" "
I too have sparks from my Thermadore MBBS/01.

They are coming from the right side panel as well. I wonder if this is a manufacturing default or not. Anyway, I guess I can fix this myself thanks to this wonderful website.
THANK YOU!

This is usually just 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.

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

If so, please double-check your model number on the tag so we can help you better.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
