Question about Microwave Ovens
Hello, The above microwave as had no problems until now,
It has started to switch it self on its own and sparking and arcing
if you switch it off its ok for a few hours then it starts all over again.
all so some of the touch buttons dont work.
Thanks in advance for any help you may give.
The arcing is often 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.
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.
The reason it turns itself on and some keys don't work is that you have a failed keypad.
If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.
