Microwave burnt spot on door seal

I have a 2 year old sharp carousal microwave. There is a 1 inch wide burn mark on the top left hand side between the door seal and microwave door opening. The plastic section of the door seal has melted whilst the paint on the corresponding oven frame has a burnt mark.
We first noticed a small mark some time ago but it seems to have enlarged after some face wax was heated in it.
Could it have something to do with the wax overheating giving off vapor which escaped or built up on a small section of the seal, spot burning at this point?
Is the microwave still safe to use?

SOURCE: Burning smell from microwave

This is the waveguide cover / stirrer cover.

Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

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.

If your waveguide cover is burned, it will need to be replaced. It provides important protection for the magnetron.

SOURCE: Microwave door has burnt patch: is it safe to operate?

From your other post:

The paint should be available at big box stores like Wal-Mart, home improvement centers like Builder's Square, Lowe's, or Home Depot, or hardware stores or local appliance parts stores.

You can order the plastic sheet (called the "door film") here. It is part # WB06X10490.

Be sure the mesh is clean and dry before installing the new film.

SOURCE: burn at bottom of microwave

First try cleaning the burned mark off. Dip a scrubber in lemon juice and sprinkle salt on it; this is also great for burned coffee pots. The smell can be gotten rid of this way: Boil lemon peel in water, then put the water in a spray bottle. Not only will it make your microwave smell fresh but the lemon oil will make it easier to clean. If it still smells of burning rubber, take the back off and inspect the wiring. IF you see burned wiring, please do yourself a favor and replace the microwave!

Microwaves work by making the molecules in food get "excited"-they move more-meaning, if there IS rubber burning, then there will be minute molecules of rubber in your food, which is BAD for your immune system. If it's just burned chocolate, though, it is harmless unless you are allergic.

Assuming your power line voltage is right, bearing the whole thread in mind, I'm sure you have a bad magnetron.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

If you follow the safety & disassembly info, this is not a difficult job for a do-it-yourselfer.

SOURCE: my mother's GE microwave oven

That would be the stirrer assembly. It consists of the stirrer motor, stirrer blade, and stirrer cover.

Without the stirrer in place, the oven will not cook evenly and may arc and spark.

Without the cover in place, food particles and grease can get on the waveguide and magnetron, and cause arcing damage.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you need to replace the stirrer motor, you'll probably have to pull the oven from the wall. You can download GE owner's manuals and installation instructions here.

I have a Sharp Carousel Microwave R-1460A. The disk on the ceiling, opposite the warming plate and about the same size, has severe burn marks (probably from food splatters). Any idea what that part is


see this indication and fix it. God bless you
  1. 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.
  2. 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.
  3. 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 pain

The problem is that the magnetron is arcing when it is running and it has found a couple bare spots 'exposing the metal'. The microwave uses a special industrial white enamel paint to prevent arcing, it is very important that the oven be removed from service until the situation is rectified otherwise there is a danger of shorting out the magnetron.

I put a metal pan with food inside my microwave oven. I heard a popping sound and there are now two tiny black marks pitted into the glass on the door. I can feel the two pitted marks from both inside...


Yes it is safe to continue using the Microwave as long as the integrity of the glass is not compromised and the pitted marks do not exceed 1/4 inch. The RFwave generated by the magnetron is a pretty wide RF wave beam.

If your really concerned you can take the unit to any appliance service center and ask that they perform an RF leakage test. There is really no other way to know if your leakage is within acceptable limits. I can tell you from personal experience that the ony microwave I ever saw demonstrated excessive leakage had either been dropped and had hinge or latch damage.

If your really worried about it and can not get to a service center you can do this test:
- Wrap a tall empty glass with a sheet of aluminum foil and place it about 3 inches away from the microwave in front of the area you where noticed the pitting.
- Run the microwave with a GLASS filled with water of equal size for 1 minute.
- Stand back 3 to 4 feet and watch for any signs of a spark on the aluminum foil.
- As soon as the microwave shuts off check the dry foil wrapped glass for any signs of heat.

(No heat.... no problem. Sparks or Heat = repair time.)

Thanks for choosing FixYa.

It may be a shorted high voltage diode.

Since it's less than one year old, it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

You can contact Sharp at 1-800-BE-SHARP (1-800-237-4277) or visit them online.
