Question about Frigidaire PLMV169DC Microwave Oven
We have the same problem with the same microwave! From day one, brand new microwave and it sparks a blue light behind the wave guide cover and makes a noise like a bug zapper. What is the deal? Is this a bad microwave? It does it regardless of what we are cooking, but it sometimes stops for a little while and then starts back. Should we get rid of it?
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.
They are 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.
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
