SOURCE: Waveguide cover for Kenmore microwave

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: interior cardboard/foil piece fell off revealing small chamber inside oven--still safe?

This is the mica or plastic waveguide cover. It protects the waveguide and magnetron form grease and food particles.

Assuming you're going to scrap the unit, carefully clean the area around the outside of opening (watch for sharp edges) with a lightly damp soft cloth.

Then use alcohol or a hair dryer, etc. to be sure the area is dry.

Then you can use a couple of strips of clear packing tape to cover the opening and trim it with a razor blade so only about 1/4" or so extends out from the opening.

Note that I only recommend this procedure on an oven that is going to be scrapped. If the oven will see continued use, a new waveguide cover should be purchased.

No, that is the "waveguide cover".

It provides very important protection for the magnetron.


And always keep it clean according to your manual's instructions.

SOURCE: What is the cardboard cover inside my microwave for?

It may not be cardboard - it may be a material called mica which is located over where the magnetron is located in the unit. This is a protective cover and if it is what I think it is, do not remove under any circumstances, otherwise you may render the microwave unsafe to use.

SOURCE: IS MY MICROWAVE NOW UNSAFE TO USE - CAN I DO OWN HOME REPAIR?

It sounds like what you are describing is called a "waveguide cover". You can purchase a replacement from a local parts supplier, or on-line at www.repairclinic.com. It is very easy to replace.

Why is there a burn hole inside the oven, on the cardboard?


That's actually a mica "window" (cover) for the microwaves to come out. And it sounds like the magnetron started arcing and burned a hole in that cover. Either that, or some food (frequently spaghetti sause) got splattered on it, and the microwaves heated it up so much that it burned a hole in the cover. Does the microwave oven still work (heat)? Do you see or hear any arcing? If the microwave oven still works and there is no arcing, you can just replace that cover. Check SearsPartsDirect.com or RepairClinic.com.

WHY DID MY MICROWAVE OVEN BURST INTO A FLAME AFTER 30 SECONDS ON HIGH POWER? TWICE. LMV1314B bought Jan. 2008


Hi,
Actually you don't need to replace the microwave, you just need to replace the carboard piece or "wave guide" and replace the magnetron inside the microwave behind the cardboard piece. The magnetron will commonly arc out to the wave guide if the wave guide gets something that splatters on it. The repair isn't cheap because the magnetron costs about $200 and the wave guide is another $30 or so, but if you replace both these parts you should be good to go again.
The magnetron usually have 5 years warranty, however you need to speak with manufacturer itself for the same.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

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.

That's the waveguide cover.

If your waveguide cover is burned or damaged, it will need to be replaced.

It provides critical protection for the magnetron.

You should be able to get Galaxy parts from the Sears site.

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number at the Sears parts site.

A full Galaxy/Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########
