My Samsung 1000W microwave from several years ago still works well but some of the paint on the bottom is peeling. The oven has a carousel to rotate food. The paint directly beneath the carousel plate track (as 3 tiny wheels of the carousel track are constantly in contact with the bottom of the microwave) has started to peel and the bare aluminum is exposed in some areas.
I have stopped using the oven but was wondering if this is a big problem (i.e. dangerous) or not. I unplugged it because I was thinking that since now some bare metal is exposed then the microwaves may cause electrical arcing.
If the paint serves as an insulator and reflector of microwaves then can the paint in the track be re-applied and if so what kind of paint?
Do I need to discard the microwave?
Thanks, Walter
