  • Waveguide coverSparking and arcing in a microwave can be caused by a damaged waveguide cover. Try removing the waveguide cover to see if the problem persists. Once removed, the waveguide cover can be inspected for burns, which will indicate if this is the issue. If the waveguide cover is burnt or will not stay in the proper spot it will need to be replaced.
  • Cavity/Rack supportIf sparking or arcing in your microwave is near a rack support, any exposed metallic area can be covered with a microwave cavity support. It is also recommended to replace the rack supports in this situation to ensure the issue is resolved.
  • Cavity paintIf sparking or arcing in the microwave is visible on the side walls, the paint covering the metallic areas could have worn off or chipped. This can possibly cause pitting in the side walls or ceiling. If this is the case, it can be repaired with microwave cavity paint

    SOURCE: my microwave oven has are rust spots;can I paint over them?

    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.

    I wrote about it an hour or so ago, with no answer. My Emerson microwave is developing some rust spots along the very sharp edge of the " floor " where the door shuts on it.


    Could be grime. If that is rust then maybe there is too much humidity at the location of the microwave. Could also be old age.

    The microwave oven coating is peeling and exposing rust spots. what can I do to fix this? Do I need a professional repair person?


    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.

    I have 3large brown stains on the lower portion of the back panel


    Probably rust stains bleeding through, try CLR. Don't get it too wet or the panel behind it will rust more. Use one of those vacuum type cleaning machines that spray a little and picks it it back up Good Luck. We owe this attempt in honor of Billy Mayes.Good Luck

    I have a Spacesaver Microwave (manufactured 1988) that still seems to work ok, but I noticed on teh back wall under the glass tray the coating has rusted away. Should I continue to use this microwave?


    Hi,

    As long as the oven's metal bottom is sound underneath the rust, there isn't a problem. The cooking chamber walls are so thick and highly conducting that they reflect the microwaves extremely well even when they have a little rust on them. However, if the metal is so rusted that it loses most of its conductivity in the rust sites, you'll get local heating across the rusty patches and eventually leakage of microwaves. If you're really concerned that there may be trouble, run the microwave oven empty for about 20 seconds and then (carefully!) touch the rusty spots. If they aren't hot, then the metal underneath is doing its job just fine.

    Thanks.

    My microwave is rusting inside. mainly the area where the turning wheels meet the base. I have sand and painted with microwave paint but after a few weeks the paint area around the wheels is rusting again.


    try the microwave touch-up paint again but this time clean the spots you sanded with rubbing alcohol. also make sure the rollers turn freely

    Microwave door has burn spots on the glass of the door...


    The brown spots are usually grease / smoke deposits. Usually there are indeed two sheets of glass in the door. If the grease is not arcing or smoking, and the metal screen / mesh (that blocks microwave leakage) is not damaged, then it's likely better left alone. It might be useful to boil a few cups of water with a little vinegar inside the microwave to help dissolve the deposits. In case you want to take it apart, I have attached a photo from a similar model that illustrates disassembly of the door. It is not necessary or advisable to remove the door or hinges when disassembling the door.
