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

I'm replacing a westinghouse 3504 microwave oven BUT...the new one isn't here yet. inside the oven/cooking chamber is a small, rectangular recess that WAS previously covered by a foil coated cardboard panel, which has now fallen off. what is this small recess? is the oven safe to use until my new one arrives? can i/should i improvise a covering for this recess, and if so with what material?

Thanks from single dad, father of 2, from all of us.

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.

I have a Panasonic microwave and it has rust inside is that dangerous?


It should not pose a hazard as far as operation goes.. only if it becomes a sanitary issue..

Clean the interior per mfg suggestions.. and you may have to clean it more often now that you have this issue.

Microwaves cannot travel through metal.. you can actually use small pieces of foil (flat pieces) in most microwaves to shield items.. without any issues.

Best of luck

The cardboard foil piece is falling apart. Is it dangerous if don't put any?


That is a piece of Mica that is called the Wave Guide Cover.
It is very important as it stops food particles from entering the magnetron output aerial.
You must replace it. Contact an appliance repair centre for replacement.

Arcing inside microwave


unless you are familiar with these, leave it alone. Over time small particles of food become carbonized inside the oven, hence the electrical display. the solution is to clean it after every use.

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.

Metallic-like cardboard insert inside microwave is crumbling???


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:

http://www.a-1catalog.com/wavandstirco.html

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!

Set up Oster Microwave


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.

Hole in plastic on inside of door


check the conductivity of the plastic with an ohmmeter by placing the probes an inch apart on the plastic surface. If the resistance is large or infinity, the plastic probably performs no role in stopping the microwave radiation. If so, any epoxy probably can be used to close the hole safely. Make sure you don't use too much and if possible place tape over the repair and orient the microwave so the epoxy presses against the tape while drying to prevent it from oozing into any door hinge/close mechanism. Otherwise, a piece of microwave door glass from a broken unit can ge glued over the hole and should stop the radiation. You can check for leakage with test units but be very carefuly anyway.
