No this is something you can repair yourself. Take sandpaper and gently rub rust spots until smooth. Then you need to get ceramic touch-up paint and repaint rust spots.

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.

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

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.

This is due to spills, accumulated moisture from steam / condensation, or both.

It can also be worse if your internal cooling fan is not running, or if the vents or filters are blocked or clogged.

Let it dry overnight with the microwave door open.

Once that's done, you should occasionally look for accumulated moisture on the floor of the oven and keep it dry.

The model number tag should tell you where it was made.

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.

Enamel should work, but appliance paint is better.
