INSIDE A MICROWAVE | How to fix a buzzing sound in your microwave and replace the magnetron yourself

[@SchmitaEclipses]

Would have liked to hear noise it makes when running.

[@turbanwearersblow]

Same here. Mines making a weird noise and would’ve liked to compare

[@HB-cg4jv]

@@turbanwearersblow what kind of noise? i have a weird clicking noise, it sounds like a relay switch that pops on and off, and when i tilt the microwave it clicks on and it starts heating, when i untilt it and let it sit naturally it starts clicking on and off and doesn't heat at all...

[@turbanwearersblow]

@@HB-cg4jv was a random surging electrical sound. Almost like something was shorting out. It was an LG brand unit that I only had for about 15 months. Think that the A/C unit deprived it of power. Had a Panasonic unit before that and it lasted like 7 years, so I bought another of those

[@CarolinaCowboys]

I wish I would have recorded the noise before tearing into it but as others have said it is like something getting electrocuted sound.(if you know what that sounds like!)

[@mrsvan001]

@@turbanwearersblow Our LG Grill microwave is also making a sound like that - buzzing electricity as if building up, and twice it made electric 'popping' sounds. LG checked it the first time while under warranty (

Sharp metal on wooden table. Next project, repair wooden table lol

[@CarolinaCowboys]

LOL, it sounded worse than it looks. No damage done

[@MyVinyldollsandMore]

Would like to know why or what your microwave problem was before you changed it. What type of noise, was it not heating the food🤷🏼‍♀️

[@CarolinaCowboys]

I know I wished I would have recorded it beforehand. It was making a loud buzzing sound at random.

[@JbBackFeeble]

Why doesn’t anyone ever show the noise so people watching will know if that’s their issue?

[@CarolinaCowboys]

Sorry about that, I didn't even think about it until after I tore into it. But if you have any kind of buzzing that isn't part of the normal microwave sounds there's no other component that makes that sound, unless you have a broken fan maybe, but this is a common repair.

[@quentinsturdivant4349]

Google is why.

[@peopler2stupid165]

My 2 cents worth: There are MANY helpful videos on KZbin for diagnosing and repairing a buzzing or non working microwave. Here is a mini compilation: A faulty High Voltage Diode can cause the Magnetron to buzz and still work / or not heat at all. A faulty Magnetron can buzz and sometimes heat the food and sometimes not! A faulty transformer can make an annoying buzz under load but the magnetron may still make heat. (It is NOT always the Magnetron or High Voltage Diode causing the buzzing!) A faulty High Voltage Capacitor can keep the Magnetron from making heat. •It is cheaper to watch the various videos and learn how to test the pieces than it is to just guess and buy unneeded parts! •It’s worth the extra $12-$16 to replace the High Voltage Diode at the same time as the Magnetron. When removing the microwave from the cabinet, you should protect the range top below with a piece of plywood with a few heavy towels under it in case you slip while handling the unit. A friend repairs appliances, he said Do It Yourself handymen often try to save a few dollars and repair their microwaves by themselves but end up dropping the built in microwaves onto the range top and end up buying a new microwave AND a new range. He refers to it as “Good for Sales”! . •A clothes basket turned upside down on the range top and wedged under the microwave provides support when removing and re-installing the microwave into the cabinet. It’s very light and is a valuable extra hand when trying to hook the back of the oven to the wall bracket and holds it in place until you get the mounting screws threaded into place. With some common sense you can successfully repair your own microwave. No harm in trying to fix something you were going to throw away ! ALWAYS UNPLUG THE UNIT! ALWAYS DISCHARGE THE HIGH VOLTAGE CAPACITOR! Hope this helps someone! 🤞🏼

[@CarolinaCowboys]

You should be doing videos!

[@andrewcpham]

Great details. Thank you for outlining other potential issue.

[@billhill839]

Great tips, thanks!

[@vencent8329]

im going to buy a new microwave 😪😪😪😪

[@CarolinaCowboys]

It wasn't that hard. :-)

[@chrizmatiq3932]

mine makes an unusual loud buzzing noise, the fan (noise) stopped working and it heats extremely fast in less than a minute at 100w. Could it be the fan that's broken or the magnetron as well?

[@CarolinaCowboys]

The fan not working could be a secondary issue, but the buzzing noise is the magnetron going bad.

[@kco0]

chirz same with me and my fam

[@925209]

I have this exact model microwave and the magnetron just died. Your lucky that the grey box above the magnetron did not burn. That grey box on top of the mangetron burned and the the microwave guy basically told me get a new one. I was pissed.

[@CarolinaCowboys]

What part? There's basically only 3 things, the magnetron, a transformer, and a capacitor, and they're all pretty cheap to replace.

[@A.C.71]

Mine is crackling randomly ( sounds almost like a geiger counter detecting radiation) when the microwave is not in use..sounds like it coming from around the lcd display. any ideas???

[@CarolinaCowboys]

Sounds like it could be the light relay. Are your two lights working underneath?

[@duckpond-studio]

nice work, I don't think I have the patience. It was good to see what I am locking at.Thank you.

[@CarolinaCowboys]

Glad I was able to help!

[@gracecollins8415]

What problem does a very soft whistling sound suggest?

[@CarolinaCowboys]

That could be the cooling fan going bad, or it could just be dirty.

[@Moezza_D_cat]

Can we use micro even though noise is coming from it please reply

[@CarolinaCowboys]

Yes you can still use it but your food may not heat up

[@bhorstkotte]

Or just buy a new microwave for a hundred bucks

[@CarolinaCowboys]

Try $650

[@KevinMoker]

I never knew you could fix a microwave. I would have just tossed it, but mine is a higher end one too. Glad you did this video.

[@CarolinaCowboys]

There are other opinions that say I should have thrown it away, but ya know...

[@waynewayne9693]

@@CarolinaCowboys eh to replace mine was 157 and the new one 207 plus it being 12 years old I just got the new one but yours being 50 made it repairable. Definitely gonna be relative to the machine and part price.

[@Buciasda33]

You should have placed a piece of tape on the buzzer while you wore inside

[@CarolinaCowboys]

We always turn it off anyway

[@TomyCroSound]

New microvave has thin aluminium case - vibrate. Soundproof when put finger on case. Can i glue armaflex on aluminium inside to reduce vibration?

[@CarolinaCowboys]

Are you sure the vibration isn't coming from underneath?

[@TomyCroSound]

Yes, i m shure. I even opened it, there is no protection on the screws (hisense). The sheet metal is very acoustic, it rings and vibrates. To begin with, I put some rubber tape, when I buy something for damping I will stick it inside.

[@CarolinaCowboys]

I don’t see why you couldn’t do that being careful it’s not touching anything spinning or hot

[@Pfirtzer]

I need probably a magnetron for a Whirlpool microwave, I live in Europe , we have a 220-240 AC can or is that an issue when buying a magnetron?The cheapest I could find in Europe was 65 euro, including shipment.

[@CarolinaCowboys]

If the model matches your unit it will work

[@macleanclassics]

Watching you flip that microwave around on top of the wood dining table made me cringe....at least throw a towel or piece of cardboard under it first.

[@CarolinaCowboys]

Ya...

[@dadthefixerflorida]

I replaced the magnetron and the diode and the capacitor. It’s still making the buzzing noise and not heating. What else could it be?

[@CarolinaCowboys]

Sounds like you got a bad replacement magnetron or the wrong part!

That's what it sounds like

[@jewermank8536]

Nice camera work man. Mine is buzzing too, but it's not as nice as yours. Probably not really worth the repair being 20 years old

I've found that microwaves haven't changed much in 20 years, unless you want convection I suppose

[@craigmankey9011]

The magnetron in my microwave was buzzing and getting hot when when the microwave wasn't running. I bought and installed a new magnetron but it's still doing the same thing. Is it an issue with the transformer or possibly the capacitor?

[@CarolinaCowboys]

If your Microwave is getting hot even when it's not running, that is definitely another issue since the magnetron only activates when the microwave powers on. Is your light always on inside the microwave?

[@craigmankey9011]

@@CarolinaCowboys I thought maybe it was one of the switches. I unhooked them one at a time and the buzzing stopped with the top one unhooked. I plugged them all back in and now the magnetron isn't buzzing or getting hot but it does make a high pitch whining noise that seems to be coming from the board. I can get a new control board off ebay for $30. Is it worth trying? The microwave seems to work fine now other than that whining noise.

[@CarolinaCowboys]

@@craigmankey9011 There's basically only 4 main components, the fan, the board, the capacitor, and the magnetron. If you've already replaced the magnetron I would replace either the capacitor or board next.

[@paulmonk7820]

@@CarolinaCowboys You forgot the high voltage diode, which is often the cause of no heat.

You got it right, that the magnetron was bad, but how did you know that it was the magnetron before you even opened the microwave oven? Thanks

[@CarolinaCowboys]

The microwave was making a buzzing sound when heating was activated. I probably should have shown the symptoms beforehand

@@CarolinaCowboys I thought you were a psychic because you bought the magnetron even before opening the microwave oven, LOL. Good video though, thanks.

[@scottvan1898]

How did your diagnosis the magnetron went bad ? Not the capacitor or the transformers ?

[@CarolinaCowboys]

@@scottvan1898 Because of the buzzing sound, I don't think the capacitor or transformer would make that sound.

[@rev3609]

Hmm 🤔

[@CarolinaCowboys]

It really does work!

[@kwixotic]

I consider myself "reasonably" mechanical(heck, I work on pianos) but I probably wouldn't go to the trouble of attempting to fix this. With my luck I wouldn't be able to get the thing back together! I do suspect though that the magnetron is the problem with my occasionally buzzing microwave. If it's doing that intermittently does that mean it's only a matter of time till the thing breaks down and can't function to cook anything?

[@CarolinaCowboys]

Correct, it's only a matter of time before you will start seeing sparks. My philosophy is to take apart everything and if I can't fix it I was going to throw it away anyway. :-)

[@v31.48]

Your Magnetron is located on the top.. The waves enter the cavity through the mica sheet that's placed on the ceiling of your microwave. (They can't go through the holes)

[@CarolinaCowboys]

Interesting!

[@netdude]

I noticed the new magnetron didn't seem to fit properly and you had to use some brackets to hold it in place. Can you explain that a little? I have the exact same model and need to replace my magnetron as well. I used your ebay link but fear I'm going to have to jerry rig the thing like you had to. Any way to determine if the bolt-hole pattern is correct? Thanks!

[@CarolinaCowboys]

Yes, the part number is correct, but the bolt pattern was slightly different. I just used some clamps I had laying around to hold it down and it's not going anywhere, but perhaps its jerry rigging, or what I like to call "creative problem solving".

[@netdude]

@@CarolinaCowboys thanks for the quick response! I'll purchase it as well and prepare myself with brackets like you had. Appreciate the quick response!

[@netdude]

@@CarolinaCowboys sorry, one more quick question. I pulled up the Amazon link and eBay link. It appears both have different part numbers. Do you have any suggestions?

[@CarolinaCowboys]

Sorry, the Ebay link is no longer valid so I removed it. The Amazon link is the right one. Best of luck and let me know if you need any help!

[@danieledwards8779]

When you find that your mounting pattern is off, I would rivet it on. If I don't plan on replacing it for a given length of time. Say at least ten years.
