How To Fix An Arcing Microwave For FREE! Don't Throw It Away Until You Watch This Video! 

Thank you from a very GRATEFUL disabled woman on a fixed income..I really did Not think this would work ,cuz my microwave is only 2 years old-but cheap. That "wave guide" was actually not a metal- it was more like a cardboard type of material. It bent while I was attempting to remove it😲 So, I cleaned it in place...and IT WORKS! 👍👍

I appreciate this because this problem keeps happening to me with different microwaves and I'm glad to see how easy it is to fix instead of having to buy a new one. Thank you

Thanks so much for putting this video together. I didn't realize this was the problem with an otherwise perfectly fine microwave.

It worked!!! I was ready to throw it out until I watched your video. Thank you! Thank you!

We had already put our microwave out on the side of the road for trash pickup because it was arcing and I didn’t think that could be fixed. But just in case I searched the problem and found this video. Brought the microwave back inside, wiped it off and checked out the waveguide cover. Ordered a replacement because ours was so charred it actually had a hole burned in it. The waveguide covers (pack of 5!) came in a couple days and cost about $6. Thanks for this video!

Thank you very much for posting this! Our microwave suddenly started sparking after my wife cleaned it. Turns out she partially knocked off the wave guide. I was going to throw it out, but just for grins and giggles I thought I would search the internet for the cause of the problem. I found your video and after pushing the wave guide back in place, it works fine! Thank you again!

Thank you for sharing... I did the same thing. Right now, I'm not in a position to order another part or search a appliance store for a replacement. You have helped me a great deal... with sincere appreciation...👍👏😊💕 Thanks again.🌟✨💫

Thanx it worked great!! I scraped mine off with a spoon, then i washed it with dish washing soap real good..then i put reversed the plate to the side that was less Damaged...its still working 6 months later..

So I accidentally did this to a hotel microwave and this literally SAVED me bless your soul it’s a Christmas miracle!

Helpful things like this makes RU-vid a useful and worthy site to visit.

Many Thanks Man !! Saved a relatively new MW from being binned. Had overwarmed ( burned) a wheat filled heating pack and thought I'd cleaned interior adequately. But no ......scary arcing continued & I thought it would explode !!!! Your tips have saved the hassle & expense of replacement. I'll keep an eye out in future. Thanks again 🙂

Thank you so much!!! 185.00 on a microwave and I almost tossed it out and bought a new one! Took off the little board and scratched off the burn marks with my nail and back up and running perfectly!!! So glad I seen this!

OMG! Thank you so much for this. I followed your instructions and it worked! I am an over the road truck driver and this really made my day

my friend,i saved now,like you,just replacing this mica protection,now is back one life

Totally worked. Thank you. You are the man!

You saved us. We hurt our hotel microwave and this worked like a charm

Thank you very much! You saved me, i was about to throw away my microwave, greetings from Mexico!

Thank you very very much I have fixed it this morning, I usually clean this on the outside but never taken it out great video

Thank you. I bought my microwave last year and it decided to start sparking and making that terrible noise. I followed this tip and so far so good. I'm so relieved! I thought I had broken the microwave forever.

Thanks buddy. this worked. I was about to order new microwave. Saved 40 pounds.

Worked like magic! 5hought my microwave was FCKED, thank God.

In an old Microwave, you may well need new Mica for sparking caused by arcing wave guard cover...I've just had a very large 30*50 cm sheet of it delivered to me from espares in Birmingham UK which cost £7.99 + p&p (so large it can even be used as a 'Wobble board' musical instrument)... Mica is cheap so get a big piece... why not!? If any of my neighbours in the future have a sparking microwave... I'll have more than enough spare to fix theirs too! Absolutely fabulous customer service from espares.co.uk! Nice video...

THANK YOU!!! Worked great and saved me a bundle! I cleaned mine to get me by and ordered a new cover.

It works man!!! This is a very valuable video, thanks for sharing this knowledge to everyone 👍

Thank you! Our microwave was arcing and had a fire on the side! I thought it might have been doomed to be dumped/recycled. But yes, there was black soot and crud on the wave guide. We gave the wave gude and area around a good clean and all working again. .

I did this years ago and found it on RU-vid but it wasn't you I never seen a coin scrape the stuff off but I wiped it off put it back in there and for about 4 years now it's been the same one and it still works just fine but I was googling because my daughters went bad and I was just going to send it to her to show her what I was talking about and I couldn't find anything I finally found you so appreciate it because it is a fixed quick why waiting on the part or what have you but it does work My microwave's 15 years old maybe older and it has the same wave wider all this time

Ok. I am NO repair person AT ALL 😃! But ... I tried this and OMG IT WORKED!!! Thank you so much for sharing😇

Now the stress of looking for repair shop is over! This is 2021! And this video solved our problem, tried it 15 minutes ago and it's now working...I just have to flip the wave guide cover cause I've noticed some scratches where the burnt part is and that may have caused the arcing...otherwise, I might buy a new wave guide cover instead...over all thank you for this video!!!

Yep. Helped. Thanks for the vid.

Wow, this could save us a few hundred dollars. Our microwave started sparking yesterday. Didn't happen again until today. We'll see what happens. Like the Dixie paper plates. We use them ourselves. Saves time from washing the plates.

I have one of those high end microwaves. GE Monogram. Cost $1300 new ten years ago. Well it was doing the same stuff and your suggestion worked. Completely stopped it. Thanks!

It worked!!!!!Thank you for making this video!!!!!!

I did just what you told me with a dime and my microwave works just great thank you very much for saving me money appreciate it again thank you

Was looking at replacement £90. after your tutorial cleaned and turned card around 2 plastic rivets. working perfectly. New blank on order eBay £2.75 inc del. Lucky to read your post. Thanks from Mid Wales.

Thankyou for sharing. I needed to replace the wave guide because it burned a hole into it. I found wave guide board on Amazon for $7 and all I needed to do is cut it to size and drill a couple of holes in it. Very easy fix!

Thank you. It worked perfectly. My wave guide has 4 little ears that slip into slots, but they are very fragile and are easy to break off. But---a little piece of tape will keep it in place for a very long time and is also very easy to replace.

What you're referring to as a waveguide is actually the feedhorn window. It covers the waveguide feedhorn to keep food splatter out of the magnetron plumbing. The waveguide is a rectangular pipe from the magnetron to the feedhorn which is an impedance transition from the magnetron to the oven cavity.

It seems to have worked for me. So far no sparks anymore. I cleaned that board you showed with a coin and cleaned the microwave inside. Thanks!

That fixed my microwave...Thank you 👍

Worked like a charm. The top edge of our waveguide cover is kind of exposed to splatters-even with the tabs and plastic snap fastener. Seems like there would be a better design. Thanks so much for posting this!!

Thank you, I ordered a new micah board and it works fine again.

Hi, Naym from Cape Town South Africa. Thanks for the video! I have that problem with my microwave, seems like the problem is solved now. Once again thank you for your help it is. much appreciated. the family is also very happy now, especially my wife.

Thanks for the video! I have that problem with my microwave, & I noticed that I have a lot of debris on the top of my microwave. I am going to try cleaning it & see if it fixes the problem.

OMG!!! It worked! Thanks so much for this video

Thanks so much Zack. I have the arcing problem so I'll be putting your solution into action. I hope it works for me

Thank you for the advice .

Thanks for this, worked like charm.

Thanks this video had my microwave running again in 5 mins

Wow! Thank you! I was skeptical, but fixed it no problem! Who knew it was so easy....

Thanks!!! This vid really helped.

Wow so glad i came across this was going to be purchasing a new microwave again.

Gently shaved the browned areas of waveguide cover with a sharp knife including edges. Disposed of shavings with wet paper towel (to avoid inhaling) Found some rust on the interior roof. Used scotch bright to clean. You may need to get some microwave oven cavity paint to touch up any place where the paint is chipped. The chipped areas can arc.

thanks sir. really helped me. otherwise I was planning to buy a new one. Thanks. :-)

Thank you for this video! This is what was happening to my microwave and got a wave guide and fixed the problem.

Dude you'r amazing thanks alot u saved my microwave

Thank you. It fixed my problem

Thanks for the tip. Works like a charm. You saved me $89!

Thank you for this video. It saved me from buying a new one.

Thank you so much bro nuff love and wishing all the best to you 🙏🏾👍🏽

Worked for me too! Can't imagine what a repairman would charge. A service call is at least 50 bucks.

Worked for me. Thanks

WORKED ON THE FIRST TRY! Thank you!!!

yes this does work I went to my local hardware store and I paid eight bucks cut out the pattern with a exacto knife and replace no more arking thanks

My plate didn't even appear dirty but I took it out and washed it, problem solved. Thank you!

Thank you so much it worked saved me money

you just saved me $50 to $100 thanx a lot bro!

Thanks for sharing this tips, it works!

Thank you! Worked like a charm.

The burn occurs on just one side of the mica. So in my case I cleaned it as much as possible, and then reinstalled it, but did so with the undamaged side now being exposed instead. In my case the mica sheet was simply a rectangular shape, so installing it the opposite way around, was very easy to do.

Steven seagal would like that microwave He blows one up in every movie :-)

Even if I ripped it whilst scraping, it did work and thanks to you I have a full belly! May the microwave god bless you with many more microwaves in your lifetime!

Thank you. Your solution fixed the problem!!!

worked like a charm

This fix worked for me. Thanks

Im so glad i seen this video, it worked after i took the guard off & cleaned it but my boyfriend still doesn't think its safe so I guess he'll be the one to buy another one because im in not in my mind I fixed it and it's good to go😁😁

Excellent and helpful video

Thank you for sharing this info

THANKS SO MUCH...although I had to get creative...I followed your advice to use a coin to scratch off the dirt from that board - but...our board had a small HOLE in the middle of it...and when I scratched the BACK of the board with a £1 coin, some “skin” of it fell off... ...so I got CREATIVE...and used “UHU” glue to stick some of that discarded “skin” on to the HOLE to cover that hole...and put the board back in...and...our Microwave stopped sparking!

Thank you so much for sharing this kind of video. With the help this video I fix my microwave oven problem. Once thank you thank you

Thanks man, it actually worked

thank you...it really works.✌

we always cover our food with a plastic dome lid made to stop splashes and such. It saves the mica card and interior. Before we used to get arcing from fat, butter and anything that has any type of vegetable oil in it. Just an FYI

Just saved me money! Awesome video

thanks man it worked, but i cracked the plate cleaning it, its pretty thin everybody, but its working, becareful when you clean it

Thanks a lot, man you saved us a microwave.

cleaned the mica board including scraping some metal burn marks off with a coin, now works fine. A new board looks like it might be around $15 but until mine starts giving more trouble I will leave things as they are.

Thank you I really didn't want to buy another microwave.

thak you this worked!

Thank u and thanks youtube!! Saved myself $$$ by simply buying the mica board from online for a few $.

thanks man, you just saved me a few dollars

Im going to try it in the morning! Hope it works.

Thank you! This saved my microwave

Thanks gonna try it. Hope it wrks

Just mended mine with this video. Thanks
