Try replacing the screws with larger ones. Maybe you ordered the wrong piece, if your microwave comes with a mica cover (A fine, square piece of mica) and you received a plastic one, you will need to get the right piece or adapt the one you received.
You can get the mica cover on any microwave service.

SOURCE: Sharp R403 microwave internal electrical short/fire

This is a simple problem & solution.

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


The waveguide cover (also called a spatter shield) is usually about the size of a playing card and often held in place by a plastic rivet.

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.

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

You can order parts from Encompass here or you can call them toll-free at 866-779-5835.

Hi. Our 1 1/2 year old Sharp KB6524PS Microwave Drawer: While cooking oatmeal, at start of cycle, the microwave started arcing, then smoking. Shut off at 15 seconds. Microwave-safe china used.


I expect the arcing came from the waveguide cover or aerial cover having either a crack or carbonised food particles on it.
A new cover may affect a cure if the magnetron is not damaged.

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

Is it dangerous to use the microwave without a duct cover


Yes, the waveguide (duct) cover protects the waveguide and the magnetron from damage caused by grease and food particles getting on them.

The waveguide cover (also called a spatter shield) is usually about the size of a playing card and often held in place by a plastic rivet.

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 area is charred or chipped, the area will first have to be sanded smooth and cleaned and dried thoroughly.

If the cavity metal of the oven is cracked or split, you can use a small amount of steel-based epoxy such as JB-WELD to patch the crack or hole.


Once that dries thoroughly, you can sand it very smooth.

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 critical protection for the magnetron.

That's the waveguide cover you're talking about. It covers the opening in the side of the cooking cavity where the microwaves enter. The oven will work without it, but if you don't have the cover in place, food particles can get into the waveguide and cause problems. You can buy a replacement here.

How do I install a waveguide in a Sharp microwave oven? The old one burned through because of corrosion beneath it. I sanded it & repainted with rust preventative paint. I don't want to break it during...


If you mean the waveguide cover, those are almost always mica or plastic.

They would normally install by sliding them into slots in the cavity or ceiling, and sometimes they are held in pl;ace with a plastic rivet, too.

If a waveguide cover is damaged, it should be replaced with a new one, not repaired in any way.

Arcing will occur, which can damage your magnetron, waveguide, and / or chassis.

If you mean the waveguide itself, which channels the microwave energy from the magnetron to the cooking cavity, that cannot be removed or replaced. They are welded in place. If the waveguide is bad, the oven has to be replaced.

We have quite a few Sharp service manuals which cover disassembly and parts lists, etc. If we have it, I can point you to a link to download it free.

Feel free to contact me directly with your model number.
