Thank you, very helpful. And just a safety reminder that the capacitor in all microwaves is a high voltage one, it holds charge even when the whole system is unplugged and it can seriously and dangerously cause electric shock.
I hypothesize that your magnetron wasn’t the problem but it was the door switches which caused it to keep running without a fan and overheat your magnetron to the point it blew the thermal fuse and cracked your magnet.
I think you are right except of the door switch. Think about new, properly working microwave. None of the state of the door switch (off/on - open close) should not cause cooking mode (if the timer is off)
I had the same issue. Just 4 years old with a GE model JVM3160RF2SS. I felt lucky that it was me that heard the noise the first time. Someone else may not have recognized it as a problem which could have easily created a fire.
Same problem with my GE microwave, only 2 years old. I'm getting tired of the garbage appliances lately, not only by GE, but by just about every common brand. It's like they all got together in a meeting and figured out a way to maintain competition amongst each other while still ripping off consumers.
I'm so annoyed at this problem right now. I'm just going to unplug the damn thing and plug it back it back in when I need to use it. A royal pain in the ass
While trying to figure it out (reset circuit breaker in panel, google, youtube, GE reviews) one reviewer said they slammed the door a little harder than usual........and the problem went away. One month later, microwave still working.
I think you made a wrong conclusion in the end about the broken ring magnet caused all you problem. It is more important what you said in the very beginning: you had two stages: 1) Cooking all the time when door is closed 2) Nothing works. I guess at stage 1 the inner fan that is cooling magnetron did not work. This caused overheating of magnetron, then failure of the ring magnet and only after that turning off heat fuse. The main reason is in something (relay or other switch) which is turning magnetron without inner fan.
Just fixed my microwave with this video thanks for reminding me about the cracked magnetic problem I thought I had other issues lucky I had a spare magnetron and it works now for how long not sure
I just had this problem arise when I was replacing the door handle. I replaced the handle and closed the door and it started running. After unplugging and replugging the unit in, it still was started to run when I closed the door. I found out what the mere problem was. I thought I had properly fitted the inner door gasket or frame on the inner part of the door but I did not. After making sure that inner frame or was properly fitted....it solved the problem. Before tearing your microwave apart or getting a NEW one, maybe its just that inner door frame that is not properly fitted.
if it is still running after you open the door , it may be the 2 micro switches (latch) on the door ( some of them have 3 ) or the main relay inside to turn on power. Don't play power on magnetron, power transformer or the capacitor its about 5000v and easily kill humans............. due to this problem while door open it it is working there is radiation hazard.
A lot of people consider this as a helpful. How did it help other than to take a decision to throw out microwave. Did you replaced magnetron with the broken magnet and it did help? It does not seems help to me since magnet is a consequence but not the main reason
@@u-tub7072 From this, I found that a small piece of paper folded up and taped to the frame, kept the door away from the frame. This resolved the issue and I didn’t have to throw it away. I was going to pitch it until I saw this.
@@JeffScherer treat this as a coincidence: You had completely different problem with your microwave (does not cook when it is supposed to work), vs the microwave of the topic-starter (cooked when it is not supposed to, before the magnetron burnt due to non working cooling fan)
I have a Samsung microwave with similar issue. With closed door it makes buzzing sound and when I put water in it it makes it hot. No light inside when door is closed. In my case a relay on control board was defective. It was sending power constantly to the the element that creates microwaves. The relay model# f5h-dc12v-p1
thanks for the video. I think I have a very similar issue. My Microwave makes a buzz/humming noise when we close the door and now its not even heating anything up when we run it. So we unplugged it.. I am also assessing if we should just purchase a new Microwave instead of trying to figure out if the Megnatron or something else is the issue... Do you have any recommendation?
My guest likes to stop the running of microwave by opening the door on it's way of running and then left with the door open until one day I found it makes sound after I closed the door . The microwave can't stop making sound after I close the door and became very hot hours later . I have to unplug the microwave so it stopped . I replug ,the same issue happens again . I don't know what's wrong with it . I have to call someone to check .
Were you able to fixed that problem?..what was the cause of this prob. Coz i facing the same issue. With my Samsung micro oven. Plz.if u can answer what was issue finding?
Had a similar issue, pretty sure it's the control board power relay. No way that thing should be running automatically. Mine I think died with the monitor interlock switch, it was completely seized closed which is fed by the power relay. I replaced the switches (all 3) disconnected the power relay and everything seemed ok but of course no magnetron. Anyway, this is #2 of the same model, first one had the door switch issue. Complete garbage.
I take that back, I know it was the power relay. I unplugged it, heard it click, now the unit completely functions. No way I can trust it though with a bad relay.
Same problem. I don't understand why the microwave would still heat food with a broken magnetron. Why was the magnetron running unless power was being applied? I'm curious if the broken magnetron was the effect of something else in the circuit or in the controls.
Robert - the magnetron probably broke from running without any food to heat. It overheated and cracked, plus blew the thermal overload that he showed jumpered out. Same thing would happen if you ran the microwave empty for a few minutes. Usually it’s a sticky main relay or bad control board that will need to be replaced that is causing it to run without clicking on the popcorn button or something else.
Exactly ! I suspect the issue may have been one of the 3 door relays allowing the microwave to run after shutting the door. This may have then caused the magnetron to fail.
@@bmoore3199 Ok. This same thing happened today on my Kenmore microwave. It was caught (noticed) immediately. It still cooks with the door closed, so it works. I'm starting with the switches after reading your comments. Thanks.
@@highqualityhomemaintenance7565 any luck on yours? I just changed the switch latch that holds the 3 switches and after the replacement, when I close the door the microwave starts by its own and won't stop
I pressed turn table off for the first time and now the thing won't stop running. There are forbidden buttons you shouldn't press on microwaves apparently
I replaced the magnetron and the microwave would cook perfect but then the Cooling fan world not self activate. I would have to manually turn it on. After trouble shooting i determined i also need a new key pad/control pad. With that additional cost i ended up buying a new microwave.
Thank you, very helpful.

any switch can broke in 2 different ways: keeps ON all the time, keeps OFF all the time. Neither should run magnetron as long as the timer is OFF

Thank you very much for your video. I just fixed my microwave switches.
great job, I decided to junk mine and get a new one was more cost effective for me. Your video helped me decide what was best for me. Thanks
Joe Smith
Glad i could help, good luck with the new microwave.
Instructions unclear. Spider got irradiated in the microwave and bit me. Now I'm crawling on the ceiling.
Very informative! Exact same issue we experienced.
Thanks, I experiened the same thing. I was very lucky to have been in the kitchen when it failed. Model number: GE JVM1630WTC01
You smelled a slight burning noise I know what your saying just busting em😂
GE use to mean something, this microwave is just a year old...P.O.S...
I'm so annoyed at this problem right now. I'm just going to unplug the damn thing and plug it back it back in when I need to use it. A royal pain in the ass

I think I will try this tomorrow.

For how long did it end working?
@@altansukhganbold5558 around another 3 months then it finally went out with a bad transformer
I think I’m just gonna buy a tea pot.

That was the first comment that make sense here and is related to this video. Everything above is a B.S.
I found parts to put in my computer now im warming up food inside of my computer
Same problem with a CEB1590SS3SS. Very expensive microwave which will not turn off.
thanks for the video.

Do you have any recommendation?
After I ordered the part it would work but then the digital screen stopped working. I ended up finding a new one sale and bought it.
Same thing with mine currently. I’m no electrician. Probably just gonna buy a new because mine doesn’t even heat right now
Did you get a price ?
I appreciate the video. It helped.
Your welcome.
Don't ever work on a microwave. Very dangerous. Better to just get a new one.
Ground capacitors to bleed off charge, right? The magnetron is stuck on with mine too. Probably cheaper to replace the microwave at $200.

No luck on mine.
I found out it was the circuit board. That's $200.
I ended up getting a new microwave.
Probably I’ll just buy another, and set this my Panasonic microwave aside. 😊
The part is about $80 and a brand new microwave was $350ish...
yes very relatable has one myselfs
Do you want Fukushima? Because this is how you get Fukushima
crap this is prop my problem. it was the latch which i fixed and now this crap happened ughh.
I pressed turn table off for the first time and now the thing won't stop running. There are forbidden buttons you shouldn't press on microwaves apparently
What was the out come?
I replaced the magnetron and the microwave would cook perfect but then the Cooling fan world not self activate. I would have to manually turn it on. After trouble shooting i determined i also need a new key pad/control pad. With that additional cost i ended up buying a new microwave.
Ok, thanks. I was thinking that was the final outcome. Congrats on the new microwave, although it’s always awesome to successfully fix something.
