I cleaned my AEG KM8403101 M/wave Combi-oven but there's still brown muck on the roof, so using a plastic spatula (not sharp), some came off but so has some metallic material. What is it &

SOURCE: Replacing lightbulb in Sharp R953M combi microwave oven

most microwave ovens built in the last 20 years do not have an
access panel to the light bulb. you must remove the screws on the back of the microwave that hold the outer sleeve in place.
Then pull upward and backward on the sleeve to disengage it
from the front lip of the chassis. the light bulb should be close to the front of the microwave behind the control panel. Some lights
are not unscrewable from the socket, but the socket and bulb
come as an assembly.

SOURCE: Paint off inside top of microwave exposing metal. Safe to use?

It would be dangerous to do so. Any exposed metal inside a microwave is source for sparks and is extremely hazardous. I would recommend getting the paint job done up, or even better, buy a newer model.

That piece is called the waveguide cover. Emerson calls it a spatter shield. Behind it is the hole where the microwaves enter the oven. Its job is to prevent food spatters from getting into the microwave source, and it's not a good idea to run the oven without it.

The cover is usually held in place by a plastic rivet that pulls out. I couldn't find the part number for the cover used in your model. But here is a link to a parts place that has several covers available:

If one of the covers shown looks like yours you can order it. Another possibility is to contact Emerson at 800-695-0098. This is the number they give to locate authorized servicers near you, and you might be able to order a replacement cover through them.

Hope this has helped. If so, please take a moment to rate the solution. Thanks for asking here!

I just removed my sticker today, and the sticky adhesive would not come my tv either. I tried alcohol first and to that only worked a little. Then I even tried warm soapy water(thats what sharps customer service told me to do) but that didnt work. So I put a razor scraper inside a rag with soap and water on it and that put little scratches on my new shiny black bezzel which made me very mad. The scratches arent really bad but who wants that on a new tv. FINALLY THE ONLY THING THAT WORKED WAS THE WD-40 NO MESS PEN. YOU RUB THAT ON THE STICKY ADHESIVE THEN WIPE OFF WITH WARM SOAPY WATER, WORKS REALLY WELL ONLY DID IT 2 TIMES. TO BAD I DIDNT DO THAT BEFORE ALL THE SCRATCHES. IF YOU DONT HAVE THE PEN I THINK YOU CAN JUST SPRAY REGULAR WD-40 ONTO A RAG AND WIPE.

I did the same thing. Order parts at thegourmetdepotco.com -- This problem is caused when you put the rubber gasket underneath the blade instead of above it. This causes two problems: 1. It lifts the teeth on the jar away from the teeth on the drive gear, which can grind down and break off the teeth, and 2. If the drive gear contacts the rubber gasket, it will melt the rim of the drive gear. In the future, to reassemble the jar after cleaning, first put the rubber gasket on the jar, then the blade, lastly screw on the base ring.
