Microwave mica board sparking




By dareceo on Oct 29, 2009

" "
Our kenmore built in microwave started spraking this morning. It looks like the mica board on the inside caught on fire and when I look behind it, there is a pipe leading in that has burnt through.

Any ideas before I replace?

That's the waveguide cover, a critical part of the oven.

This arcing is usually due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

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.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

If your waveguide cover is burned, it will need to be replaced.

You can just enter your full model number at the Sears parts site.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########
