The coating on the bottom under the turntable is peeling off and there is a crackling noise and more peeling going on if

The crackling (which sounded a little like a geiger counter) which I could hear when the oven was NOT running was coming from the speaker (where the beeps come from). I unplugged the oven, found the little speaker on the circuit board, yanked one of the wires off of it, and the crackling was be gone.

Is it a carousel (turning platter)? if it is, than it is probably dirt on the platter support wheels and the platter support groove/track on the bottom of the oven, clean the glass plate, the support wheels, and the bottom groove as well, if you want to make sure the crackling comes from the carousel system, take it all out (support and platter) than place a glass of water in the oven and start it, if there are no crackling noise than my theory is correct, if the noise is still there than have it checked by a professional technician...

Are you sure the plates were Microwave oven safe? Some dishes have metal in the colors of the design. A snap, crackle, pop noise normally means there is metal present in the oven.

A couple of months ago my microwave started making crackling, rattling and grinding sounds everytime i used it and i thought it was going to break down. It turned out one of my children must have spillled or overflowed something with a clear liquid because the micro did not look dirty but there was a crunchy substance under the wheels of the turntable. Once i cleaned this up totally the noises all went away.

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.

How nice of them!
Often it is caused by the use of hand cremes affecting and tarnishing the metal coating or the plastic pigments.Many items suffer from handremeitis
including the letters on keyboards car door handles, AC knobs etc etc.
Unfortunately it is the way of life that is associatedkin care and vanity.

You should re-paint it using microwave touch-up paint.

Yes, 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.

Otherwise, you can have rust and arcing.
