J G When I took a microwave apart I used a pair of insulated screwdrivers, although it had been sat in the garage for years... no spark at all. Oh, and it turns out that the capacitor had an inbuilt 10MΩ bleeder resistor, so a more reasonable resistor should be just fine.

Multiple claims here are FALSE. Show me one report of anyone killed by the capacitor. It has an internal 10 megohm resistor to bleed off any residual voltage for safety. The rating on the capacitors is shown on the side of them, 2100 volts, not 3 to 5 thousand. What he claims is a resistor is instead a high voltage diode and part of the tank circuit. Find videos that describe how it works. Almost magic. . My credentials: I invented coin shrinking, 50,000 volt capacitor bank producing a .75 million amp pulse for 4 microseconds and worked with a 3 million volt Tesla coil also, for example and was tutored by the man who invented the world's first automated heart defib unit, so many patents he stopped counting. Fun fact: His favorite TV show back then was Mr Rogers Neighborhood.

When it comes to working on live current, you should work with only one hand when possible, because when working with two hands, a path for the current exists from one hand to the other. Placing one hand in a pocket to prevent contact with grounded work surfaces while performing energized electrical work is done to prevent electrical current from flowing through the heart.

A very sensible comment. This is not emphasised enough in many fields of training and employment. An electrician told me this when I was an apprentice. Best keep one hand in your pocket! The left one preferably. The strange fact is that this same guy never used a mains tester when working on the 240V supply; he just used to tap the wires with his finger to find the live one. I noticed that he always wore boots with thick rubber soles though. No kidding, this is a true story.

Maybe 10 megohms as a discharge resistor, much lower and the dissipation would be too high and cook the resistor. The electronic/electrical crowd use a capital M followed by an upper case Greek letter omega (Ω) for megohms... 10MΩ. 0.2 milliamps flow during the peak of the cycle, 2,000 volts at 0.4 watts. Don't open the capacitor... they are oil filled, not toxic, just very messy. The waveform is a mess, huge ripple with a peak voltage up around 2,000 volts, down to less than 1,000 volts at 60 hertz in USA and 50 hertz over here in NZ. Our capacitors are 1.2 to 1.5µF for 50Hz. The reason that diodes blow here is because the mains voltage is 230 volts and we don't need such a grunty diode to rectify the high voltage. . Our primary has approx 1 turn per volt and about 1,600 turns in the secondary. Yours would be 110 or so turns in the primary with twice the cross sectional area of copper and 1,6oo turns in the secondary. A lot lower impedance ergo, a higher current available. If you reuse a microwave transformer, don't forget to remove the magnetic shunts before you rewind it. Those shunts are just "I" laminations to compensate for the weird waveform being put out onto the grid because of the half wave DC rectifier. . I use a rewound transformer for my "hot knife". A heated 304 stainless steel blade for cutting plastic ropes and sealing at the same time... carving plastic foam, etc. 3 turns of 4AWG cable to the element mounted on a bit of heavy duty industrial Formica, heat controlled by a "variac". I also have the mandatory spot welder using 2 identical transformers, primaries and secondaries in parallel for higher duty cycle or welding power. Secondaries are 2 turns of 0AWG and controlled by a timer and heavy duty relay from a foot switch. . I also have an unmodified transformer that I use as a break finder in cables. This is mounted in a toolbox and has 2 push button switches that must be pushed at the same time but are further apart than your fingers can reach... a safety feature. The high voltage comes out to 2 crocodile clips on the end of some 15 kilovolt rated flex from a neon sign. The clips go to either end of the broken wire in the lead which is spread out on the concrete floor of the workshop. Plug in the box... put on the clips, push both buttons and wait for Mount Vesuvius to erupt. Takes about 5 seconds and a hot flame forms where the break is and this burns through the insulation. Don't do it inside your house... it stinks and burns wooden floors and carpets. . Have fun BUT be careful. Further thoughts... Maybe that cap with a 10Ω resistor is a "snubber", a device that reduces sparks across contacts. The resistor limits the inrush current and the capacitor slows the voltage rise rate. Value of the capacitor could be 1µF but not a big metal job, more likely a plastic box type. . My apologies Kevin for taking over your post.

[@rolandsequeira]

I have fixed 2 microwaves Samsung and IFB and tried to short the capacitors with a plier before touching them but they never pop or crackle like it's being discharged already right when just plugged out.

I will be discharging them pretty soon here for fear that they will represent a danger to me and my family.

My house is equiped with an actual vent outside for the fume hood so that was a challenge to get the pipes lined up so it actually blew outside. A year or so after use the relay that turns the Megatron on would not engage. A swift tap to the section under the bottons will unstick it every time and it cooks perfect.

PLEASE READ EVERYTHING BEFORE REPLYING.

Second of all that's not a resistor that's called a "Diode" the microwave transformer puts out between 2000 and 2800 volts AC and it runs through the capacitor and diode and doubles in voltage because the diode and capacitor make what's called a "Voltage Doubler" and that feeds the magnatron with 4000 to 5600 volts DC it gets half wave rectified so it's actually half DC but point is your really incorrect about what you are saying I've taken apart like over a hundred microwaves and other electronics and I mess with them constantly and those transformers are really good high voltage power supplies but please DON'T DO ANYTHING WITH MICROWAVES IF YOU DON'T KNOW WHAT YOUR DOING IF IT IS PLUGGED IN DO NOT OPEN IT USE YOUR COMMON SENSE AFTER IT'S UNPLUGED THEN YOU CAN OPEN IT and unless you want a good buzz just use some pliers and open them and shove each end into a separate terminal and you might see or hear a discharge but all of my days of fiddling with microwaves I've never saw or heard a discharge off of the capacitors even right after unplugging and running them and if you didn't actually cook with the microwave then you don't even have to discharge it cause no power would have even gone to the capacitor just use common sense please and stop spreading false information and research before making a video for the sake of people like me having to type all of this thank you and please don't take this as offense im just teaching you :).

Actually, not entirely correct. The output of the capacitor-diode circuit is at 5000 dc, but only while its running. The actual voltage of the capacitor is 2 100 square root 2, which is roughly 3000 volts. Also, that is a zener diode, not a resistor, and sometimes, the capacitors have a pre-installed, internal capacitor, rated at the mega ohm region. So even if you take apart the microwave immediately after using it, the voltage of the capacitor would have dramatically dropped

This is the stuff that urban myths are made of. I could be a smart arse and ask you to name them, but I won't and this is why... Most people just throw the stuffed microwave in the rubbish, drive down to their local big box store and buy a new one. . Those who pull the old ones apart for the bits in them have watched these sorts of videos and are aware of the "dangers" that lurk inside and short out the high voltage capacitor without killing themselves. They don't see a spark when they short it out as there are discharge resistors fitted inside the capacitor. If you are silly enough to power up a microwave and grab the high tension leads from the transformer... tough. Instant Darwin award. . If however the discharge resistor has failed and you get across the terminals, you will get a belt equivalent to that from an electric fence. The energy stored is around 1 joule. The terminals are small and reasonably well shielded and unless you are determined to put one finger of each hand on a terminal, all you'll get is a belt across one hand. Doctors apply about 300 joules when using a defibrillator. . If you are stupid enough to pull the magnetron apart and grind up the beryllia insulation and inhale the dust, you may cause chronic beryllium disease which could kill you... many years down the track. . Throwing the transformer at someone may kill them if you hit them in a vital spot. Maybe that is how people are killed by taking them apart.

[@BigBadJones]

Yeah. Good luck with that. Hopefully you never get a reality check next time you tare apart a microwave.. the only thing that discharges the capacitor on most microwaves is the mag. If it happens to be an open circuit then the capacitor can still be charged and it's will hurt you if don't know what your doing. I know someone personally that died because of this.

[@wateryblaze]

As a retired electronic tech, the main failure in NZ is that the magnetron fails, takes out the diode... goes short, blows the fuse and all is safe. I've only come across one incident when there was any charge left in the cap and that was just a few volts from the pathetic little spark. Yeah, I short them out too. All our current batch from good ol' China must have a built in discharge resistor. Maybe your first lot didn't or maybe they were faulty back in 2008. Ever worked on a microwave tempering (thawing) tunnel? They are great fun... 10 or more magnetrons all operating together. You take precautions so that you don't get fried, either way. . I feel sorry for your farmer but it wasn't from the high voltage in the cap... he didn't unplug the thing before working on it. It plainly states... he was fatally injured while removing the back cover of a microwave oven. The same thing can happen if you take the back off any appliance still plugged in and turned on. I have even come across power cables in the wall that have melted the plastic coating due to continuous overloading and had the phase welded to the earth and the earth wire blown off between the switchboard and the plug. Phase on the earth and the phase wires. Luckily no one was killed. It was in the wash house or laundry. Over here we have 230 volts at 50 Hz. There are very few people who get electrocuted over here. Maybe we don't do so much DIY... don't you believe it, we are a nation of DIYers but we do it carefully.

[@BigBadJones]

@@wateryblaze i'm glad to hear you retired...

[@BigBadJones]

@@wateryblaze I've never seen a shorted diode cause a fuse to blow , just makes the microwave growl . A shorted capacitor will blow a fuse.

[@wateryblaze]

I started out as a domestic repair tech and finished up as a industrial electronic tech. Worked on and in some scary situations... X-ray transformer servicing - 64kV a few inches from your hands, under oil that eats rubber gloves and makes them slippery as hell. Lepel treater that etched the surface of a polyethylene film with high voltage and frequency to make the plastic take ink and adhesive... a form of Tesla coil generator. Ward Leonard motor speed control of DC motors up to 200 HP and 300 volts DC. Plastic injection molders with 80 tons clamping force with faulty controllers scared the hell out of me but I'm still in one piece. Worked on the electronic controls in 11 kV sub-stations. Ever seen one of them hit by a surge? I have after the fact. It makes a hell of a mess. I'm glad to be retired.

[@TheOpoas]

First I read about taking apart a microwave oven I saw info on that capacitor. I just let the microwave sit for about two months before taking apart. I was more worried about Beryllium Oxide poisoning from the magnetron (that's even how I got here). But I'm still alive so it seems I didn't do anything wrong.

[@wateryblaze]

A 1 microfarad capacitor with a 10 megohm internal resistor fitted will be safely discharged within 10 seconds or less. A screwdriver or similar shorting device will do it in less than 1 microsecond. Two months?

[@TheOpoas]

@@wateryblaze I had it in a garage for about two months. Partially because I didn't have time to disassemble it.

[@wateryblaze]

Fair enough.

[@seanholloway5296]

I've been scrapping over 20years(in England )and have taken apart thousands of microwaves and never knew this to be true can Somone explain why I would get a shock?

[@ktoutdoor]

I think the newer Microwaves have something called a bleed off resister that is supposed to drain the capacitor but I would not trust them. Watch this video I found to see the power of a microwave oven. kzbin.info/www/bejne/aGLEg2uImt-Xh5o Do you research and be careful...

[@e_wa.n5036]

Well a capacitor stores potential difference(voltage) much like a battery except with minimal current. Because it doesnt store current also it can be fully charged within a few seconds and some can store extremely huge amounts of potential difference. There is a different potential between the two studs, (the amount thats stored) and bridging the studs with each other via a conductor or a finger causes the two studs to want to have the same potential as each other, hence it discharges everything quickly to get the studs balanced and that discharge shocks you.

[@Chadwickyboy]

@@e_wa.n5036 a battery doesn't "store current" either. The only component that can store current is an inductor. The reason capacitors are viewed as more dangerous is because power supplies (batteries) have resistance, and so when they are shorted the short circuit voltage is significantly lower than the rated voltage. Capacitors do not have this problem - your body will see the full voltage, and the energy put into your body is proportional to the square of the voltage. These ovens have a pretty damn high voltage.

[@e_wa.n5036]

@@Chadwickyboy well a battery is just a chemical reaction either way. Wether its charging or discharging. For explination sake i like using the word 'store' because using correct terminology can make it more complicated. For instance...the more correct thing to say is that a capacitor builds up negative charge in the form of electrons on one of the terminals, although it doesnt store them, or for instance an inductor creates current flow in the form of collapsing magnetic flux and also doesnt store current officially. A battery also doesnt store either voltage or current, instead; like in the case of lead acid batteries; the electrolyte and positive and negative terminal plates would have different chemical compositions in its charged and discharged states and the reaction between them would cause a potential difference causing current flow...nothing really stores anything but its easier explaining it that way. The difference between batteries and capacitors are the amount of potential difference the negative can push to the positive terminal. The external resistance across the conductor also plays a huge role. The resistance in the human body is around 1mega ohm and because of this the 12 to 24 volt across a lead acid battery is not strong enough to push much current between the terminals...whereas the voltage across capacitor terminals range in the several thousands of volts, sufficient enough to push what little current it pushes through your body much more easily. You do bring up a great point about the internal resistance though but i would think thats more of a definition of the difference between the two components,? But im just another person learning so yeah i might be wrong

Be safe out there folks. That red wire shocked the shit out of me

[@ktoutdoor]

Thanks for contributing.. yes be carefull

[@markpolyakov1512]

Often not as dangerous as this video makes them seem. Even a high value bleeder resistor will discharge the capacitor quite quickly. Even if there is no bleeder, as long as the oven is unplugged, the capacitor isn't ground referenced, so touching it with one finger wouldn't hurt you. You would have to touch both sides of the capacitor simultaneously to get a shock. If you did this with one finger, for example, then the current would only flow through the finger...unlikely to be fatal.

[@ktoutdoor]

Welp tore down the microwave and touched the cap and scratched the beryllium because I didn’t know what it was scrapping seems less and less worth it lol

[@santiagodavila1426]

Shit man.. thank you thanks a lot.. I already fixed my microwave once’s few months ago was the resistor, and literally destroyed te whole unit and out back on and not it’s working. and now I have and other but has no power AT ALL I was thinking either the fuse or capacitor but after this video I have no more intention to fix it anymore.. thanks a lot..! 👏👏🙌🙌

[@Psycho9263]

We have capacitors in A/C systems and Washing Machine motors. It's not enough electric to kill a person, but enough to hurt. In an A/C a capacitor is anywhere from 370 - 440VAC and it can vary between 5/45 - 5/80 uF.

[@MC_DesmondSparrs]

Omfg Im glad I didnt disassemble my microwave all the way. I had no idea its this dangerous..i think im gonna dispose of this

[@Bryankaaskoning]

I have taken apart a lot of microwaves and i never realized how dangerous those capacitors are. So next time i'll be extre carefull so thanks for the vid

[@SineEyed]

Not just the capacitors are dangerous. There are a couple of ceramic looking rings (might be white or pink) found on the magnetron which might be made with a beryllium compound. Those little rings are safe as long as they're intact. If they get broken, it's all bad - the dust released from being fractured will contain a volatile carcinogen. If you breathe any of this dust, you will get cancer, and you will die. Try to be careful..

[@antresia.9723]

I don't know why they put High voltage capacitor on Microwaves.when I take the microwave apart I'm just going to take out the fan and the display pad and that's it.

[@walter7454]

I'm not quite sure but i think a diode and a capacitor increases the voltage

[@SineEyed]

I'm pretty sure it's to deliver a sufficient charge to initiate the magnetron..

[@pyrojackal8950]

A magnetron (like every other vacuum tube) need high voltage to operate and emit microwaves. (if course high voltage DC)

You're much better off using a neon sign transformer because a microwave oven transformer uses a tremendous amount of power compared to a neon sign transformer which makes it very expensive to operate because it draws as much as 1600 watts , A neon sign transformer draws around 100 to 150 watts
