Thanks you so much, I searched whirlpool microwave removal because i havent done before and not heating popped up and I watched video on meal at work and it didn't look too hard so I ordered parts on ebay and watched your video and did each step along with you and sure enough it worked and saved me from having to replace microwave. The diode was clearly burned and not sure about magnetron yet I had both parts and replaced like you did and I am very happy with the results of hot food and the accomplishment of doing a repair so thanks again
This was awesome! I did not attempt to fix mine but it was great watching this video to know the symptoms and resolution. I learnt names of microwave components thanks to you. Your assistant was awesome with the questions! Thanks you guys!
Thanks so much for the comment! That’s why we do this. Fixing the microwave aside, these little moments are always stuck in time with my little dudes. If your microwave is broken, I hope you get it fixed soon!
Thank You for showing the symptom BEFORE the repair. Genius!
I love the little voice asking questions! :)
This made me smile. One of my little helpers. I appreciate the comment! Hope the video helps get your microwave working.
Thank you! Replaced the diode with another video and realized it was the magnetron. So, your video took it over the finish line and got mine working again. Saved me a couple hundred bucks. Thanks!!
Was yours making a loud humming and no heat?
After watched this video . I think I will buy a new Microwave lol
😂😂
Getting real tired of all my whirlpool appliances needing repair. This is the fourth repair I'll be doing in 4 years after buying new. Going to Bosch next.
Customers need to think twice before buying the Whirlpool microwave- wmh53521hz-5. When the light won’t shut off the only way to fix it is to buy a new motherboard, and they range in price from $156 to over $300 online plus tax and shipping. Also $150 for service call to install it. And it’s an inherent problem in this Whirlpool model. You can buy a new microwave for $450 or pay that much for repairs or buy an LED stick up under cabinet lights for $12 to $18 as a alternative solution.
I just fixed my whirlpool duet steam yesterday...now this. 😡
Nice job young men ....its great to see you include the young man helping you..... great video

Well finally got the Megatron installed. Found one that would work on line. $80.00 but cheaper then a new microwave. Can’t thank you enough for your video here. It was a life saver 👍
That’s awesome to hear! Im glad the video helped and I’m glad you kept in touch through the repair process. Take care!
Did Optimus Prime showed up while you're installing Megatron?
@@ryk1265 no but Bumblebee was there to be sure there are no troubles
FINALLY i have clicked through like 10 videos "how to fix loud microwave" and NONE OF THEM thought it was a good idea to have it make the loud noise in the video, they all just went straight to taking the parts out. really short sighted on their part.
Thanks so much. Great video. I watched it yesterday, ordered the parts through your link from Amazon ($42.00 for both parts.)
They came today and I installed them in about 45 minutes start to finish. Works great. The only issue I had was the orientation
of the Magnetron. The ears went front to back instead of side to side, I just installed it with the ears lined up with the holes
and just connected the 2 wires to the front instead of the side as that's where the connections were.
Works like new! Thanks again.
What model microwave do you have? I bought the same parts on Amazon from the links above. Did you swap the wires on your new magnetron? I noticed that the FA / F were not on the same orientation on my the new magnetron from Amazon. Thank you and I look forward to hearing from you!
Thank you for showing and allowing us to hear the symptom before the fix. Once I heard it, which was identical to the sound mine was making, I knew there was a good chance this repair would be my fix too. BOOM! Replaced both parts on a GE JVM6175YK2FS . FIXED! Thanks for helping me get my microwave repair degree!
Awesome!!! So glad we could help. Glad you got it fixed.
Mine is a Kitchenaid but the process should be similar, great help, thanks. BTW I'm an ace losing screws so I put them in freezer bags taped to the part sometimes so I know which go where . Makes notes on the bags if need be too.
Great video. Just finished fixing my microwave. Outside looks a little different, but once I opened it up it’s identical.
Dude!!! TY sooo much! i have the same wave, i watched this video and fixed it because of you! HERO!! ty keep it up!!
So glad I found you, ours just started making the same noise, same style it appears as ours. Do you happen to have part numbers needed for this repair?
Thanks again great timing 👍
Ok never mind, I didn’t look fat enough, you have us covered,
Thanks for the video. I have the exact same model, and exact same issue. I just ordered the parts from you’re links. Wish me luck!!!
Good luck! I appreciate the comment. It was a little intimidating at first but so glad I did it. It’s a shame that these issues happen on newer microwaves.
Be very careful. Microwaves can kill you working on them. The most dangerous appliance in the house. Make yourself a capacitor deactivation tool for changing that out also.
Apparently this is common in this model at least.... Would be nice if they made one that can at least last two years....
I have a very similar microwave and exact same problem. Replaced the $3.00 diode and works perfect.
Was yours making a loud humming and no heat?
This just happened to mine and it's a year and a half old.... The whirlpool dishwasher only lasted six months before the heating element broke... In our newly built home....I will never buy whirlpool again!!!
Funny I just searched buzzing and no heat and your vid comes up....I have the exact same microwave 😂
1. HV Capacitor from ovens built in the 1990s and newer have an integrated bleeder resistor, so no need to discharge; 2. Most DMMs cannot test the HV diode, used a 9V battery to test forward/reverse current for an open/closed diode; 3. Test the HV capacitor to verify it is a capacitor, remembering there is a 10MΩ resistor built in and 4. Test the two filament terminals on the magnetron for continuity around 1Ω between two terminals and no resistance between ground and either terminal. Only after all of these tests fail bother to replace the magnetron.
Nice useful video! Like!
Thanks for the video. I wish you had replaced and tested after installing each component, just to know what which exactly was the issue. Nice job either way
Thank you so much. I got the same problem. Now I can fixed it myself. Is it possible I could get the parts number for the diode and the megatron. Thank you once again. Its a great help.
should you be running a microwave without the cover on to shield the microwaves??
wish you would have played the sound it makes after fixing, comparing it to before. Does it still hum?
Are all magnetrons standard in power, voltages, watts and ohms, etc., and can be used as replacements in any microwave oven?
I'm trying to repair my microwave oven which is just about 2 years old, and the magnetron has stopped working. It's one of those that has a static (hot) plate - not the rotating kind. Can I use a magnetron from a rotating plate microwave oven to repair mine?
Thanks a lot for doing this. The greedy technicians were asking $400
I have a whirlpool countertop microwave model GT4185SKB -2 made in August 2002. (the “-2” at the end is the “ECN” number). It looks new inside and outside, with no food residue, no scorching and negligible rust. So I figured this machine may be “low miles.” So I just put a TV dinner in for 5 1/2 minutes. Everything worked fine, clock works, turntable spins, light comes on, and no unusual noise. But the TV dinner was still frozen. So apparently, no heat. Does this model default to the “HI” power setting? (most, if not all microwaves do). Did I not set the power setting right? Or any other possibility of “operator error?”
At 9:36 there is a black box with yellow and black wire connected. I have this same looking part and thought that was the capacitor on my model (Whirlpool GH7208xrq). What is that part called?
How about if it has NO SOUND? It was so funny, he could not take off the cover. It was so funny.
Will this work on just about any microwave? Thank you so much for your video dude.
It’s possible. Steps of diagnosis may be the same but parts may be different. Just process of elimination for me on repairs like this.
The kid has the idea to put something in to see if it warms. Haha
This just happend to our microwave. Ours was 30 years old so we just decided to replace it. But it was interesting to find out what the problem was.
Thank you the microwave is working again. was a faulty magnetron.
why you replace the diode after the magnetron was replaced? it may work with the old one?
Can this magnetron replace lg 2m226 in a similar whirlpool?
I have a Whirlpool WMH31017HS2 that made a popping sound and now it runs but does not heat... and has a loud hum to it. I have looked up what could be wrong and it's the magnetron, diode, capacitor or fuse. How do you know which one of these it is beforehand? What part would make it hum if it goes bad? I don't want to buy parts I don't need, especially if the cheapest one.. the fuse is the culprit versus the magnetron.
We're in the same boat. It made a very loud snap noise, continued running but wasn't heating. What a piece of garbage!
🆘 Think twice before you buy the Whirlpool microwave in the above video. When the light won’t shut off the only way to fix it is to buy a new motherboard, and they range in price from $155 to over $350 plus tax and shipping. And it’s an inherent problem in this Whirlpool microwave unit 0:05 wmh53521hz. The guy in the video does an excellent job showing how to replace it but you can buy a new microwave for $450 or LED stick up under cabinet lights for under $10 as a solution.
Can you send the link where we can get the part? Good video. Thank you
Yup! This is what we used:
Magnetron Replacement:
amzn.to/2Rv9zbs
Diode:
amzn.to/2Fy1xMz
Hi, Thanks for the great video. I have replaced just the diode, it was working good for just 1 day, then again got the sparks and stopped heating. I don't know why the new diode died soon. Do you think the old magnetron damaged the new diode? do I need to replace the magnetron too?
Hi! That’s one of the reasons I feared using my old magnetron and just replaced both. I would say if your microwaves symptoms match ours, I would surely replace the magnetron. I would check the part number of your existing one before ordering the replacement.
@@BrickBuildingKids Sure, I will try to replace the magnetron too. I have another microwave when I turn on it trips the circuit breaker, any tips for this issue?
Was it tripping the breaker before you replaced the diode? Is it always tripping the breaker? There could be other reasons why it’s tripping your breaker but a bad diode or magnetron leak match up with a reason it’s tripping the breaker.
@@BrickBuildingKids It is totally another microwave, did not change any diode or magnetron. Just tripping the breaker whenever turn on the unit.
Is the diode magnetron thesame for all whirlpool microwave oven? Or do i need to check the model?
Always check the model number. Never assume it will be the same.
Can you tell me what I should do
How can you check if either is defective?? Just trying to see which part is cheapest to fix, Before ordering both...
You should shorted out the capacitor with a 20 K ohms, 5 watt resistor in series with an insulated screw driver. For DYI guys a safety alert should be noted on this video. I would have use plastic insulated gloves like Ansell® 11" CLASS 0 Black Rubber Insulating Gloves. Other than these two things I brought up your video is excellent.
Cut the bullshit.The best way to discharge to the capacitor is with 2 screw drivers.I have been fixing microwave for over 35 years.
Jump it to ground and discharge it. It’s not that hard.
Maybe I missed it, but why did you decide to replace both components? Isn't the magnetron quite a bit more expensive than the diode? Why not try replacing the diode first and if that fixes it, then you wouldn't need to replace the much more expensive magnetron?
For me, all signs pointed to the magnetron. I didn’t want to be in a situation where I replaced just the diode and waiting on the magnetron or the old magnetron damaging the diode. You are totally right though on costs.
@@BrickBuildingKids thanks for the clarification
What is the model # for this Whirlpool?
@@alittleofmeisallyouneed314 not sure. I decided to get rid of it. Gave it to a guy for parts.
Any way to test the Magnetron prior to replacing it?
Look for cracks in the magnets won't heat if either one is cracked. Shake it around and listen for broken or loose pieces inside. Test the each pin with ohm meter to the metal case if any continuity it is bad, shorted.
Good info, but you need a camera that auto focuses or something. Gave me a headache with all the focusing in and out. You could have explained the pin mech on the electrical connectors to the capacitor. Other than that, great video.
Is this Microwave a wmh32519fz -0
If you own a Samsung microwave they have a ten year free replacement warranty for the magnetron. 9/10 it's the diode. Not the magnetron.
Good job teaching your child some safety.
Can you not test the diode or magnetron to see which one has failed before throwing parts at it? The testing would be good to know too.
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?
Sir, I have GE brand MV and it's not getting power supply. Have checked all parts with multi meter and it's ok only problem is not getting power supply after switching on.
Perhaps it's the bigger relay on the logic board (directly connect the two wires coming out of it) or the thermal fuses (on the magnetron and on the oven body). There are also two more fuses (one where the main cable enters the case, the other between the transformer and HV capacitor).
For me it was the magnetron that gave me these exact symptoms. Not too bad of a job
Why did you replace the $170 magnetron when it was the high voltage diode?
Another question, what to do with the magnetron?
I would check your local rules. We had to drop of off at a hazardous disposal facility.
Literally my same issue and microwave lol😮
Ok, ordered by the part number you have here but the ears used to hold the magnetron in place were different. Instead of coming out the sides they came out front and back and the plug in came out the side 🤷♂️ where did I go wrong, any advise?
I see that too! Looks like the orientation was changed on that part. Do the holes still match up?
Brick Building Kids they would have but it put the prongs sideways and the leads wouldn’t reach
Got a call into them to see if they have one to match. Haven’t been able to find one that matches my numbers on the old one. But your microwave is identical to mine , other then the part all was good , thanks for that, helped a lot 👍
@@nutthrower4415 just took mine apart and have same issue. What was the resolution?
Just a tip, never start a microwave with out anything in it to heat it.
What is you don't have that thing to check for a live wire?
Hi! It’s a non contact voltage tester.
Leather doesnt protect you. Rubber then leather over the rubber. The leather is to prevent wear to the rubber gloves. Also, when using a ticker, check a known power source first so you know it works properly.
Hey my microwave don't heat i did change magnetron and dios
What can i do now
The Magnetrons are not cheap on some models. Sometimes replacing the Microwave, is a better option if it has failed. In this case, testing before replacing did not happen. The diode is much cheaper than a magnetron. It may have fixed the problem. Less than $10.
Was yours making a loud humming and no heat?
@@marymiguel9904Mine was making the humming noise. I first tested the Capacitor. That was good. I found the diode to be bad. After replacing, the Microwave now works again. My Magnetron was fine & heating.
Can I bypass the diode
This very good video got me started on my repair, so thank you! For anyone researching a microwave repair, I highly recommend this video first: czcams.com/video/t1tdj3OnlXU/video.htmlsi=PndPjWnIl0Mqzb6q There could be multiple reasons why a microwave doesn't work, probably good to run through them all. Repairing appliances is great (saves $, reduces waste) but it doesn't pencil out if you purchase parts on unnecessary repairs. So accurate diagnostics are important. I have the very same microwave as in this BBK video. In my case, I replaced the diode first - that wasn't the problem. I don't think the link for the magnetron in the description should be trusted (in my case, the mounting points were 90 degrees off) so research your exact model number. I found a magnetron and it solved the problem. Back to quieter and hotter operation! My magnetron magnets were not cracked, but the top one was loose (it would spin freely) so I think that was the problem. The link I pasted in this comment has a good approach to diagnosing the magnetron beforehand. Good luck on your projects everyone!
Can i bypass the diode
Hello, is there any reason what causes this to happen? Bought a new one just a few months old but now it's not heating and there's a buzzing sound too.
Reason, I’m not sure. But with how new it is, I would hope you would be covered under a warranty and not have to take it apart. Sounds just like what happen to this one.
@@BrickBuildingKids Before it happened, heated up some food and it splattered so i cleaned it up with some damp towel. The next day after that, not heating anymore. Is there any chance this what caused it to malfunction?
I guess it could be possible, but I would think the diode and magnetron would be more protected.
@@BrickBuildingKids Got this. Thank you so much for your replies :)
Some PLEASE HELP my microwave says light next to the time but idk how to change it and it won’t heat up
Maybe I should add my part number just to make sure , whirlpool microwave model wmh31017hz making noise
I have the same model. Did you got it fixed and what did you replace?
@@Zionbutler8 I just changed the Megatron
But be careful. After I got mine done I still was checking around and found out the pink circular thing is very dangerous so take care, can’t find where I saw that but you might look around on CZcams for people that remove the magnets from these, that might be where I seen that
Been running good ever since 🫰🫰🫰
I could have built a microwave by now.....
My personal advise don't buy expensive microwave big brands.. After few years the die too.. The time of my parents, buying a expensive brand was equally quality.. I changed my mind.. My whirlpool microwave cost me $250 few years ago.. And broken from nothing.. Soo why pay extra money for a well known brand? If the longevity is the same as a low cost brand?
Now i will buy a $60 microwave..
Welcome to the excessive consume society..
So, just a magnetron is more costly then a new microwave ?!
The magnatron part he listed in the description is currently selling for $50 on Amazon. The microwave he is reparing costs between $250 (Best Buy) and $320 (other vendors) brand new. My general rule of thumb is if the replacement parts cost less than 1/3 of the total cost of purchase, I’m down to fix it. If it starts costing more than that, I might as well save up the difference for a new one. Especially because sometimes you get the thing open, replace the recommended parts, and still have the problem. Then its back to the drawing board, or you’re buying more parts, wasted a whole Saturday messing with it, and still don’t have a working unit.
I got mine out the trash I know it seems gross but I made sure to clean it and it never comes into contact with food
This video. $17 ebay magnetron. Microwave fixed.
Quality Mexican microwaves they make... lol
You should not test it empty.
LG my way only run about 10 seconds and is not getting hot and it'll pop off on the computer screen set f-11
The microwave Raymond about 10 months old and has been taught about a month and a half
You lucky cause you didnt test anything YOU GUESSED THAT IS NOT GOOD IT DIDN'T HELP
My microwave isn't heating up and the plate isn't spinning
For the heat, this video should help but for the turntable not spinning, it could be your drive motor. If you take the tray out does the coupler still not spin?
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?
