You are an excellent teacher. Thank you very much!!

This very practical test procedure is very clear and concise. Well explained and effective. I especially appreciated the concept of continuing testing all main parts if a fuse is found bad. As in all electrical work employing fuses or breakers, there was most likely a reason (failure of a main part such as condenser, diode or transformer) for the trip or blown fuse. Very well done. Thank you!

Thank you very much, through your video I discovered a shorted magnetron.

The video is outstanding. Thank you very much.

Well done and thank you for your effort and knowledge you share. Repairing a micro and with your instructions I found the fault , a faulty capacitor. 👍

Thanks for this tutorial. Well and clearly explained.

Thanks a lot. Your video helped me to diagnose the faulty microwave at home. Our 4kv glass fuse was gone. Good simple English.

Fantastic and well articulated I will definitely try to repair mine when I buy the tester....thanks very much

Very well done...thank you Ravi!

Sir u r very expert thanx a lot for sharing your knowledge God Bless You

Knowledgeable video sir. Thanks

Awesome explanation! Thank you.

Excellent tutorial. Thank you

Best video and the way of explaining superb ...

Soo clear and precise thank you chief

Awesome Explanation! 🙏😊

Awesome video. I found the capacitor to be bad on mine, shorted between the two terminals. Fuse blew and monitor switch was recommended (per a sticker on the inside) to be replaced with the fuse, so that'll be replaced also.

Well done bro.. lot of thanks to you

Very good video, well explained covering all safety precautions to be observed failing which, can cost yr life. Thanks bro 👍.

Great info.

Sir,if check only continuity of transformer,if it's short it also give beep, check resistance in 200ohm, and and other checking perfect ok my dearest brother,I know your language is Malayalam, you are very good 👍

Good work ❤️👍

Very good, thanks

very nice thank you.

Good way of explanation

Very, very good perfect explanation sir,but what should be the resistance of a good magnetron,in low resistance mode, continuity ok,but should check resistance also,is n't. thankyou very much 😊

Good explanation of microwave.

So so Wonderfully explained Sir.. U just earned a subscriber +1..keep up with the great work

Thanks!

Thank you for the reply. I guess you are right. I suspect that the thermal fuse and the line fuse blew. rather than the capacitor. I will attempt to fix it myself. My first step is to identify the types of fuses and buy them cheaply. If after replacing the fuses it still blows then i will have to change my capacitor etc. for now I just want to confirm that any 20 amp 250v ceramic slow burn line fuse of the same dimension can work?

Hats off Sir

Very good informative video

thank you 😊 Sir thank you very much 😊❤️

Thank you Ravi Fix for the informative tutorial. I checked every thing in my LG microwave oven using a multimeter. These are my observations. I used continuity testing. Diode is OK, HV capacitor is OK, all the fuses are OK including the thermal fuse. Magnetron is OK. Door switches are OK. HV transformer is OK except for (I am not sure) the high voltage terminal connected to the HV fuse going to the HV capacitor. There was not reading or a beep at this terminal. Microwave oven operates, but it does not heat up the food. I also cleared the front dial. What seems to be the problem? Thank you for your input.

I just went through Ravi’s video and followed every step. Turns out that my problem was the high voltage 0.9A fuse had blown. I could immediately tell because that fuse has a spring inside and the spring wire was broken with the spring no longer stretched inside the fuse. Everything else tested okay. I’ve ordered replacement fuses from Amazon. A $0.50 fix. Thanks Ravi.

Excellent video. My Panasonic inverter Microwave blows fuse while sitting idle. Sometimes after one hour and sometimes after one or few days while door stays closed. I checked all parts are ok and the microwave works good while fuse is not blown. Please give your comments. Thanks,

Thank you bro

You are very good technician but only one thing yoo forgot is to check door switches

Sirji, I have GEC microwave table top. While plugging current does not flow and front panel no light. I have checked with multimeter transformer. magnatron, capacitor, diaod, fuse termostate, all ok. I have also checked main cable,it is OK.I have not checked PCB and it is bit complicated. Appreciate if you could response. I am in CHICAgo, USA and here it is 120V.

Excellent

But still a good video mate 👍👍

Oh,ich glaube das es dir Spass macht solche Videos zu erstellen😎😎😎

Nice safe start ... then safe fail by using dead short on capacitor. Damage cap & tool and create explosion risk !!! Use a large resistor for a few minutes then check the voltage. Then do it again. Then don't die ; )

awesome

Very good

how to make sure that capicitor is dischare completely? is there any other equipment to check capicitor?

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?

Super

I have done all the checks and every component passed but the microwave is still not heating. What could it be?

does all transformer had soldier pont on top edge?

Nice

Hi Ravi, Thanks for the video was really informative. I have a microwave which have blown fuse. Tried replacing and running it and blew the fuse as soon as tried to run it. I checked all the other components and could not find any fault with any components. The only thing is I can't find another high voltage fuse between transformer and capacitor. Also when testing the capacitor, do I have to remove the diode and resistor which is attached to the capacitor.

I had the same issue. Fuse blew instantly, repeatedly. I tested everything, with the help of the video. There was no fuse between the transformer and the capacitor on mine, either. Then, I unplugged everything from just one terminal on the capacitor and found my capacitor to be shorted between the terminals... which is bad. I did not remove the diode (no resistor on mine) from the capacitor, as that was the side with more items plugged in. I left all connections on one terminal, removed the capacitor from the microwave, and freed up one terminal on the capacitor free of any connections. Then, I used the flux capacitor, and I went back to the future... ok, just kidding. I then ordered a capacitor, because I need my microwave now, not later/future. I'm not going back to the future, I am staying here with my microwave and its new capacitor.😂

for top fuse you put red wire point of multimeter on left and for bottom fuse you put red wire on right. what if is vice versa? is it dangerous?

Hi, Do all microwave use 15-20amp ceramic line fuse? i have a sharp carousel microwave that uses a 20 amp. It blew when I attempted to cook rice in it. It can been over 1 year. Can I buy any 20 amp ceramic fuse to replace it? Thanks

Most microwaves use 15 to 20 amp fuse. Before replace the fuse, should check the issue why blown the fuse.

first of all if it is not possible to find something, highly recommend please get professional person assistance. Check for corrosion or oxidized on wire connection. Duble check transformer, Make sure you have replaced right amperage fuse.

Which wire is F and FA on magtron contecter?

Model MG7040NWR, microwave 1350w, Grill 1250w, conversation combination 2650w, originally in ac income supply 12A 250vac. Original fuse white type but now available glass type in market is glass type fuse suitable for above mention. Give suggestions thanks..

If same amperage doesn't matter glass or ceramic. Ceramic fuses are more safer when it blow. Glass fuses are harmful when it blow.

what if not having 9 volt battery, then how to check diode?

And also to check TT table motor

My microwave panel on has a few touch buttons working help fix it pls

Where ur u from

The diode is used as part of the voltage doubler, not solely as a means of discharging the capacitor. Also, you did not explain how to test this diode, which is a high voltage diode, and cant normally be tested in the usual way like a lower voltage diode. You need a higher test voltage to forward bias the diode while testing. Hope this is helpful...

@pierretessier1682

You're right Richard! The diode is for the voltage doubler and it's not for discharge de capacitor

Peace be upon you, teacher. I want to ask you about the microwave does not heat up. I changed the fuse, changed the diode, and checked the capacitor, it was good. I checked the micromagnet, it was good. I said, maybe the problem is from the transformer, but the transformer when measured it looks good, but when you run the files inside it, it gets hot and when the transformer watts increases. Coming out of smoke and smell

My high voltage capacitor reads 20 megaohms from terminals to chassis is that bad

I'm not clear on how did you do the high voltage diode testing. Using a 9V battery ? 🤔

@ravifixall

Жыл бұрын

I have clearly mentioned in the video that we need a bit higher voltage source to check this diode. Because due to high resistance in the diode, it has a voltage drop. If you use small voltage source like AAA battery, you will not get any reading. Because entire voltage drop in the diode. Hope you understand.

for checking the fuse you did not mention the precise way of connecting the two pints of multimeter whether red should be on left and black on right or vice versa for both fuse. you just display but did not mention the precise way of placing both the points of multimeter. what if placed wrong?

@ravifixall

If you discharged the high voltage capacitor properly, then you don't need to be afraid to touch or check any component. Please follow the procedure explain in the video beginning. To check the fuse no matter polarity, it is just continuity test, you can use any lead to any side, carefully look for a conductive point on the transformer body to chek continuity, should be somewhere around, try it to find it by touching the multimeter lead.
