How to test a microwave oven diode. 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 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!
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.
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.
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.
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
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! 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.
@@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.
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!
@@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?
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.
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.
I am writing this to invite you to take a video on RU-vid, and you will get these multifunctional voltage tester for free. Looking forward to your reply, we can talk about cooperation in detail.
