The cardboard cover inside the microwave broke, how do I get a replacement. Is it safe to run it without it ?

Not sure why a microwave would have a piece of cardboard in it. Maybe packing material?

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 ###.########

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.

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.

you need to replace the cavity cover "the cardboard like",the antenna bearing set "the gun barrel like" and the gear motor.If the "gun barrel like" is stuck up because the gear motor is not rotating excessive heat will occur inside the microwave thus burning the cavity cover.

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!

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.

It sounds like you may be talking about the wavegudie cover. Does it cover a square hole in the side or top of the caivty? If so, it is needed. It prevents grease and food debris from getting in the waveguide, which can damage the magnetron. I would refer you to Danby customer service: http://www.danby.com/page.asp?code=5
