HI,
If you are able to spent money for a new Microwave then go for a new one.
If you are interested to repair and reuse the existing Microwave then keep on thing in mind, if you paint it then also it will not lasts for a long time as the metal underneath is rusted.

Hi,

Scratches and bare spots are fairly common, but should be addressed as soon as they arise so the corrosion will not spread and arcing does not occur.

Unplug the power cord and remove the turntable and the support that is under the turntable. Clean the surface of the support wheels or any other part that rubs on the oven cavity.

Take some mild sanding cloth or scotchbright and clean the bare and rusted areas in the microwave. Use appliance touch up paint to re-coat the surface. You can find the touch up at most anywhere that sells appliances, it comes in a plastic bottle similar in appearance to fingernail polish, yes it does have a brush inside.

Let it dry per the instructions on the bottle or 24 hours if not specified.

This is often caused by spills and condensation.

The metal will have to be sanded smooth and clean.

You can use a wire brush and naval jelly to get rid of the rust.

If any rust remains, you can use Rust Reformer paint to stop the rust process, then sand it smooth when it's dry.

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

Yes you can, it is a painted surface correct? If so buy some rust inhibitor spay or primer and spary the bottom and then paint. Make sure you tape off any vents on the bottom before you do anything

why is it rusting?

You will need to buy a appliance high heat paint. the spray can works the best.

Yes, you can paint over the spots and no, it's not dangerous. I'd let the paint thoroughly dry before using the oven -- it could otherwise cause paint to buckle/ripple/etc.

Moisture accumulation can sometimes be caused if the cooling fan is not running properly or if the vents in the back are blocked or there is not enough free space around the sides and back of the microwave.

One thing that helps is to keep the door open a few minutes after using it and to wipe down the inside after use.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

just use sand paper to clean the rust then use some high temperature paint (sold in tins) eg spray paint but it must be labeled high temperature and spray 2 to 3 coats . your microwave should be safe again

Enamel should work, but appliance paint is better.
