If you liked the video or if it was worthy to you, don't forget to give a LIKE. You can also join the Channel for more interesting videos about electronics workshop.
Thanks for watching it!
I like the format of the demonstration. Very easy to follow and clear!
This was beautifully explained. The best I found on youtube.
great help. Still I need to know what to set my multimeter at. I'm a novice so I need EVERY step
THANKS for this vid and your previous vid.
Your explanation was the best I have seen! Very clear, even for an armature like me.
i never realized the diode wouldn't polarize until more voltage was added! something i should have know, but just never really thought about. thanks that explains a lot
Hi! Then let's make a video of how to make a switch with a diode. Most of us know a diode is a one way electronic component, until we start to play with low voltage, high voltage and frequencies. That is the point when we start to forget the "ideal diode" and start learning the real electronics". Thanks Cris for the comment!
Amazingly simple setup to test higher voltage diodes! Thanks.
thank you bob i am from egypt i admire your test it simple and easy thanks
Thank you for a Great Video, as I'm testing components of a microwave that won't Heat, and eliminating different components as to why. My Diode tested good by your test. So I've narrowed it down to the Termal Fuse, so hopefully that will fix the microwave. Thanks again.
😅
Excellent! Thanks for a great video and sharing the knowledge.
Great video Bob.. Thanks for sharing
Nice video. I was able to test my diode conclusively.
I have the same voltage but one is positive and another is negative. I checked 4 times. Thank you, sir.
Nice Job. This was a BIG help.
Como,siempre,bob,muy simple,pero,didáctico y útil tu aporte.Felicitacioes y sigue adelante con tus muy interesantes videos ,Saludos from Argentina.
Like, always, bob, very simple, but, didactic and useful your contribution. Congratulations and keep going with your very interesting videos.Regards,desde Argentina.
Very helpful and informative video
Thank a lot 😊😊
Amazing video! Thanks!
Thanks Bob! Great video!! :)
Yes good explanation you got to the point Thank you
Testing Microwave High Voltage Diodes this video helped me a lot
... And your tutorial is GOOD 👍
Great tip, thanks!
Very clear, thanks!
awesome video and explanation as to why I couldn't get any readings subbed -PawPaw
Great job!
Excellent very helpful thanks🙏
excellent video!!!!
Nice job!
Thank you for the video. Perfectly explained, the graphics of good/short were well done. Thank you sir.
Very nice video thank you
Great explication! By far the best one I have found. Thank you!

👍👋🙏Great video and valuable information.
Thank you very much your video help me check my diode I like the way you explained step-by-step I subscribed to your channel to learn more🙏🙏🙋♂️🙋♂️
Very helpful
Awesome job thank you so much
th-cam.com/video/sHHMyxdxiyU/w-d-xo.html
Helped me isolate the problem with my microwave to the Magnetron. Thanks so much!
VERY GOOD, A CLEAR SIMPLE TEST

Nice video
Thanks brother
Good that is complete diagnosis. Covers everything. Mine is outputting dropped voltage in reverse mode too. So I guess it's bad :)
Thank you bro.
How can you tell the value on these? or does that matter that much I am sure their are different ones.
very importante, very likes
Thanks for you 🌹 iran
Excellent
Thank u Sir
Hey, I have microwave that blows fuse. My problem is capacitor is fine but bidirectional diode 2X062H is shorted it is connected to CL01 diode on one side. The CL01-12A diode is working. If I unplugged the one end of he bidirectional diode from the cap, will it work? I can't find the diode where I am loctated.
....two thumbs-up , great vid . shalom,a.j.
Gracias.
Hi, I have 15SQ045 SCHOTTKY diode, this method is not working with 9volt. If i use diode function in multimeter it is not short, but however when i use 9v battery it is showing 9volt on both sides even if i flip cathode and anode.. diode is good because i have more than 20 and i tried with many diodes.. apprecaite your help
Like!
how does it show when the diode leaks , short and open are good
Super 💖
I test was 1.5 on positive is it still good
Hi how r u what happens in technically if a diod get short or open in a microwave why microwave not heated
GOOD

¿¿Y el video en español Bob?? ¡¡¡Gracias!!!
Hi, my diode drops the 9 V battery to about 4V, not to about 7V. Does this mean the diode is defective? it passes the reverse test. My MW jumps the fuse. It is not due to the defective the HVT or HVC. Thanks
Hi @Alan Fani I am getting the same result, was your Diod bad or not ?
@@izrekeicitaticom It still means the diode is good, just "stronger"
I get 8.8 v with no diode... And 0.88 v with the diode (in the correct direction).. 0 v with diode in the wrong direction. Is my diode bad?
What if the voltage reading is one half of the input voltage?
Master, may i have explanation the test other kind of microwate diode, they call bidirectional diode?.....mostly install at side of above diode..
th-cam.com/video/sHHMyxdxiyU/w-d-xo.html
What about if I get 5.4volt dc and the. 1.6 milk volt on the other direction? Good or bad
Hi! Minute 2:08, 9V - Vdiode = 5.4V, and Reverse 0V or close to 0, is a good diode. But it looks like you don't know what you are doing. Please, take it seriously; you are not qualified to service a microwave oven and you put your life in danger. Bring it to profesional service or get a qualified mentor to help you. Consider the mentor's help. I graduated as industrial electronics technician, and as electronics engineer in medical equipment, but I was next to an old electronics engineer for was mentor for nine years. Thanks for ask!
@@bob.kalpon1398 Microwave stopped heating. What might be wrong other than the diode? Still in circuit, the high voltage capacitor isn't shorted when measured across terminals, so that is good. Over temperature sensor (disables microwave especially when humid wet) is 0.2 ohm both directions when measured on meter's 200 ohm setting - while removed from circuit.
@@PeopleHealthTru did you solve the problem? I am getting on the diode 3,2 V but I do not know is that enough or I need to have at lease 5+V
@@izrekeicitaticom as I wrote my diode is 3 volts across the diode and it's not shorted. I didn't replace the expensive diode. I replaced the capacitor and the magnetron and it still didn't work so I'm guessing the control panel has a problem. Your diode isn't shorted so maybe it's okay. I'm not the one to answer your question.
my multimeter gives 3.6 v does this means that my diode is broken?
What if I get voltage of 4.8v using a 9.51v battery? In a cl01-12

❤❤❤
Does anyone think a cut wire to the plug the microwave is plugged in will fry it ? Fuse is good

👍🏼
👍
can i use a 12v battery?
Hi! Be careful! ...a 6V or 12V lead acid battery can source many Amperes. It is too strong if the diode was in short and you miss handle it. It is the reason why I recommended the 9V battery.

What if I get 4.9v and the reverse 0 ? It's good or bad? Pls
I got 4.3v and the reverse 0? same result as you. Was this good or bad?, thanks.
@@eaopanama good
@@tiburon0 are there any table details, how many Volts at least you have to got that Diode is good? Some people are saying that if you get less than 5V than your oven does not heat enough, can that be a true?
I have no idea what any of this means. Are you suppose to have 9 volts in one direction and none in the bother direction?
Can lask a question purse?
Can I ask a question please?
Am getting the same voltage both ways 5.4 volts
that sounds like you used a resistor instead of a diode
th-cam.com/video/sHHMyxdxiyU/w-d-xo.html
Diod is BAD and you need to replace it with a new one. Also check the fuse and thermal fuses which is easy to check.
Dear Bob,
I was able to figure out that my microwave diode was in short circuit, thanks to your video.
(It was 9 volts in both directions), when the diode was attached to the 9 volt battery.
I was able to repair the microwave for $10.
Thanks!
my friend was electricuted when he open the microwave
Electricity doesnt kill ignorance kill
My inverter P. S in microwave is buzzing with fan and magnatron disconnected. The diode pair is reading in reverse bias a small 0.01 V leakage. Not zero. Is that acceptable range? Display works and can start but no warming and shuts off after 30 seconds or so.
Replace the High Voltage Diode and check the High Voltage Transformer because transformer seems suspected. Reply if that fixed your problem diode need to be replaced anyway shouldn't be any leakage at all.
@@skyneo823 thanks for your message. Actually fault on that was magnatron. usual magnatron tests were good but trying another mag and all good.
hello, Mr. Bob,
take a look over "gasifier"
BR,
