RF Engineer here, this just a cover to keep the bulb from getting splashed on and bursting. The cover does NOTHING to stop the microwave radiation.
Dull Men's Club
An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

It didn't make sense to me either that this cover would stop microwaves going back into the emitter but not stop them going OUT of the emitter...
Then are all lthe claims about the microwave making weird sounds and or "cooking itself" just bs? Or can all that be caused by food splatter getting in there?
You should never run one empty if thats what you mean. And on odd occasions you can get a weird skip in there that makes noises but nothing to be concerned about.

Duality of men
Lmao
It's the bonus meal. It's unlocked after using the microwave 1000 times. bone apple tea
Looks delicious.
I think I remember Mica Plate doing figuring skating for Ukraine in the 1992 winter Olympics

huh weird.. it works for me. what about this one? https://microwaveexpert.wordpress.com/2010/11/09/microwave-waveguide-cover/
Yeah that one works.
Ceramic or mica waveguide cover. Do not use the microwave without replacing it, it stops radiation getting in the electronics and blowing them up.
Mica cover does not stop radiation whatsoever. It stops boiling grease from your overheated sausage from drizzling onto the electronics.
It's still a bad idea to use a microwave without a mica cover, it's gonna stink with burning grease after a few uses.
Most microwaves do not have waveguide nowadays, the magnetron sits right behind the mica cover.
How do you clean your microwave?
I just take a bowl of water and vinegar (2:1), heat it for 5 minutes, then let it sit for 10 minutes. Everything wipes clean with paper towels. Very little risk of destroying components on the interior walls.
Thank you I will proceee to destroy my microweve by using this method and fucking it up somehow
The filth goes into the bowl, and makes a nice soup.
Enjoy!
I just microwave a wet cloth. Don't think you need vinegar, would just make it smell like vinegar.
Vinegar smell is temporary, and it gets rid of smells that last longer.
Also it cleans things. Like soap that you don't have to rinse as thoroughly. You use soap for things, right?
I just zap some tap water most of the time, what matters for the gunk is getting it steamy. If it smells funky then I use like 4:1 water to vinegar to kill the smellls and it doesn't smell like vinegar after.
I really don't understand everyone's fixation on vinegar the last decade. Influencers just kept pushing the stinkiest possible thing, and now a ton of people are just going with it.
Decade? Vinegar as a cleaning agent is 100s of years old. Influencers are just the 21st century version of “old wives”.
I always cover my food so the microwave never gets dirty enough that a damp rag can't wipe it up the odd small spill easily. Are people just raw-dogging their microwaves and letting it all cake on in successive rounds of use? There's always these life hacks to cleaning them but it's not hard to clean if it doesn't get dirty in the first place.
I genuinely never cover the food. Doesn't that make the food heat up slower?
We just clean it once in a while. If the food can pop (like meats and such) we cover those.
No, it makes it cook quicker and prevents it drying out.
I feel like a caveman now, thanks!
Microwaves heat up water molecules inside the food you’re heating. But there’s a limit to how even it can heat. Covering food helps capture the water molecules that end up as steam, which in turn helps everything heat up more evenly.
Helps…. yes, but it ain’t magic. Also you may prefer all or some foods drier. You do you!
I usually cover the food, but sometimes it boils over.
I'd almost never use the microwave for myself, but I've got three kids and I'm always in a hurry. If something does spill over I'll give it a quick wipe, but it builds up. Plus if I'm steaming vegetables in there, there's a residue even if it is covered.
It's an important shield thing, you should replace it with a new one. When ours failed it caused the microwave to start to do very loud and distressing electrical arc zapping sounds inside.
TIL! While dull, super cool
Mica dust is bad for your health. Just FYI.
See the comment under mine for the correct answer(microwave cover).
If you find the model number on the tag, you should be able to order a replacement cover from somewhere like Amazon or similar.
It's not, it's a ceramic microwave cover
Wow, that is a nasty looking screen.
It is just a cover on the microwave generator so that it is protected. I think you can get a replacement easily. It is not critical to operation.
Google: microwave mica sheet replacement
It's critical if you don't want to microwave the internal components
Its pretty critical to operation unless you want a single-use appliance
