Video is good, but it would have been better if voice and explanation were added side by side.
Sa lahat po ng nanonood ng video ni sir sna po wag po natin skip ang ads nya para makatulong tyo s kanya.maraming salamat po godbless
Maraming salamat sir and God bless po...
Agree, tinutulungan tau ni sir pro Tech. Kailangan din natin magsupport sa kanya kahit man lang wag iskip ang ads.
good video...irritating music.. the best thing about this video is that you showed the difference between good and defective (transformers/capacitors/diodes & magnetrons) thumbs up to your video
Turn down the volume?
Ohne Worte, leicht zu verstehen wie Bauteile einer Mikrowelle geprüft werden können. Klasse!
Thank u. Pag disconnected n ung mismong magnetron tube sa filament terminals nachecheck nman na wala na shorted. Medyo mabusisi lang magpalit ng filament terminal pero I think worth it nman than to buy a new magnetron. Make sure lng cguro n maayos ang gawa para wag mag karoon ng arcing. Thanks again for your very helpfull response and videos. Keep safe always, bro.
Great job, most comprehensive easily understand video
You're the best man who did video tutorial uploaded.. easy to understand thanks Alot my friend☺️may god bless you
Maraming salamat sir s kaalaman kng paano malaman ang sira ng hv transformer at iba pang parts ng microwave
I see a lot of video
Your video is very good
Thank you very much
Good .defective compare is very nice
Very important you check and show analog meter well dane god bless you.
Thank you
Good one, you are a professional in this
Thanks a lot 😊
thank sir sa info about sa pag test pyesa na ginagamit sa microwave
Thanks for sharing ideas boss, baka pede mag test din kayo yung may supply voltage nman sa next video nyo..
Very good testing process 😊
Great video! Thank you! It was very easy to understand.
Please mention when you test on which range u have set the multimeter and what should be the reading of good and defective what you are checking
Very straight to the point. ❤️
Thank you sir. Your video gave me lots of knowledge.
Very simple to understand
Good Job
Excellent ❤❤❤.
thx now i know the bad ones
Thanks. It was very easy to understand.
Heavy varnish on laminations is a insulator on transformer! Base where it is bolted to chassis would be better to show up shorts between coils and laminations!
Maraming salamat po sir malaking tulong po ito sa amin.godbless u sir
I think the "symbol" of the diode is inverted,
But the measurement is correct.
Nice video sir thank you ng marami
Nice thanks dito sir more power sa channel mo
Good video
salamt po kuya . dami ko natutunan
Nice tutorial bro thanks for sharing,
thanks for getting knowing Godbless..
Thank you. Great video.
Reduce boring odio , good
Nice bossing thanks for sharing..
Maraming salamat din bossing.
Another interesting and sourcefull video. Thank you sir. God bless and be safe.
Ser tnk u po sa learning
Does magnetron has a polarity or if I connect in reverse will it blow up and is there any way to find its polariry
No polarity
@@protechelectronics79 thank you sir
Nice practical
Nice tutorial boss idle
Thanks so much sir
How to check they with digital multimeter? How to set it? Can you write in description the setting ex Mega Ohm for magnetron ect. Thanks
Hello sir.good day to you.if the value between HV terminal and body shows 75.4 ohms,its good condition or bad.?
Good job sir god bless you
Good job bro
Great video! Thank you!
Nice
Thanks for sharing sir
Salamat sir...God bless
Thank you for sharing. Very Useful Information. New legit friend . . You got my Red support.
Thank you sir.
I performed the test on the magnetron and the results would suggest that it is fine. I notice NO crack in the magnets either. I have a Panasonic Prestige 1300W inverter microwave oven. The issue was that it would chip the breaker after 2-3 secs. The switches tested fine. If I disconnect the magnetron from the inverter board microwave does not chip out. Once I connect it the issue occurs again. Any insight?
Try to change new magnetron.
What is the multimeter settings for transformer.... Can't see in the video.
Ohm
@@protechelectronics79 thanks sir
Boss baka puede rin mag video kong paano mag palit ng door switct at turnanable switch ng microwave oven salamat
i like your video
thankas
boss ask ko lang, checked na po lahat good ang transformer, good ang capacitor, good ang lahat ng fuse good din po ang magnetron, pero lagi pa din blowing ang main fuse, ano pa po kaya ang reason, baka po may na encounter na kayo na ganitong scenario, tnx
Check po yong mga door switch, may upload video na po ako tungkol sa ganyang problema check nyo na din po.
If mark value of capacitor is one microfarad and measured value by a DMM is .87 microfarad. Then capacitor is ok or not. Waiting for your kind reply
Very informative! What should be the normal capacitance for microwave HV diode? I replaced the original HVR-1X 3 with CL04-12 HV diode, now the microwave is heating the food. I set the digital multimeter to 200M, the original HVR-1X 3 reads 7.5 and the new CL04-12 reads 17.
Does it works?
Useful sharing
Thanks for this very informative post. I checked all HV components on my Sharp R89ST, to find them ok, but found the HV diode had gone down taking the HV fuse too. The only other thing was the HV capacitor discharge resistor had failed. But this is not a requirement to run.? My microwave now runs in all functions but does not heat the food despite the case above the magnetron getting warm. Any ideas where to look more deeply next. Cheers.
Nice sir
Thanks sir...
PLEASE WRITE ANSWER..I WANT ASK THAT BECAUSE CHECK TEST THE PRIMARY WINDING FROM TRSNSF.MICROWAVE IS 2.8 OHMS. ITS GOOD OR NOT? THANKS FOR ANSWER
Do I have to take the transformer out to perform this?
No need to take it out, just disconnect the wire connections of the transformer and check.
hi po, ask ko lang po, pag digital po ginamit q pang test sa diode wla po sya reading pero pag analog meron po ano po kaya problem?
Sa digital wala po talagang reading pero sa analog may mareading pero sa high resistance.
nice video boss
Salamat boss
Thanks a lot
IBIG SABIHIN PO BA HINDI KAYANG MADETECT NG ANALOG TESTER YONG SIRA KAYA HINDI MO PO GINAMITAN NG ANALOG TESTER?
Kaya nman po, digital lang ang ginamit ko para makita ang saktong reading ng resistance bawat winding.
Hi great video - tested my transformer -
on hi voltage winding I am getting 82.6 it’s a zebra 100TT in 120V & 60 hz -
On other side getting .4 not .5 to 1 1/2
It’s a Viking microwave with oven -
Microwave works just no heat up food - the sound is a lot less then before as well - change Magnatron - changed Diode and high voltage capacitor and all switches - do you think it’s the transformer ? With those readings above that’s bad ? Thank you !! Michael
thanks paps
Nice content sir keep posting god bless
Salamat po God bless..
Sir continuity lng ba ang ginamit mo sa pagtest ng short to Ground ksi ung tester ko Hindi auto range anong range po ang gagamitin ko kng magtetest ako sa winding to body tnx sir
Yes sir continuity lang
Sir pwede bang ipalit ang 0.75 sa 0.85 capacitor ng microwave
Yes pwede po.
Sir kapag OL or open yung last test mo sa hv xformer may prob? dapat ba at least nasa hundred ohms yun?
Yes po
Sir tanong ko lng po Yung nabili ko mot ang reading sa tester ko po sa hv output nya ay 208ohm,good po ba ito? Salamat po sa sagot😊
168.9 ohm line to ground is good? Should it be 0 right?
Typical Readings on a Microwave transformer: Filament winding:
Thanks
good
Sir, ok lng b n ung filament terminal n lng ng magnetron ang palitan? Ito nman ang laging nagiging shorted. Madami kasi ako nakikita dito s youtube n palit filament terminal lng at meron nman nabibili nito online para makatipid sana. Thanks
Pwede nman sir bastat sigurado lang na mawawala ang shorted.
Merona inaayos microwave midea problem pumuto or nag spark magnerton pinalitan ko ma magnetron at Capacitor
Ganon parin
Sir umuusok po ung transformer ng microwave ko sira na kaya un saka ung diode nya sir kapag tinester ko ng baliktaran may reading
Sira na yon sir kung umusok, shorted na din ang diode kung kabilaan may reading.
What is the black measurement device replacement of the digital multimeter???
Analog meter.
salamat boss...pwdi magtanong? saan pwdi makabili ng ganyang mga pisa?..wala kasi dto sa cebu..yung legit na online site..
No idea boss kung saan pwede omorder online.
Mantep gan
Master tanong ko Lang po ano pinang di diischarge nyo sa high voltage cap?
Short to ground lang po...
I don't understand why you tubers are adding background music.
Can we use any side for diode
sir saan makakaorder ng mga parts nito hv cap, mgntron hv diode,
Check nyo po marami po yan online or sa Raon don po ang bilihan.
Boss sir magkanu po magpaayos sa inyo ng sony smart tv 42 Inc ? Ok nman po yung sound nya ano lng po yung sa screen nya walang lumalabas😊😊thank you po😊😊
I checked all parts twice and thought they were all working.. realised my multimeter shows 1ohm instead of 0.. so magnetron is shorted.
Costs a bit much to replace.. not sure the cheap version on AliExpress is worth it. At best 1/3 the microwave price. 2/3 for the more expensive version on AliExpress.
Transformer Magnetron HV capacitor ka price kya kya hai thank you
Ed Aranaz ask q lng sir hinde b pwede Ang multi tester pang test sa high voltage trasformer at anng pwede pang test sa RK
Pwede nman sir gamitin ang multitester, nakasanayan ko lang kasi gamitin ang digital at makukuha mo ang saktong reading.
@@protechelectronics79 tnx po sir God bless
Noisy sound track ruined rhe video
Really wish you'd state what setting you're using and show what exactly it is you're touching the probes to. This video was next to useless.
Sir ano po yon Value ng diode salamat po
CL04-12, 450mA 12kV High Voltage diode.
hello sir ,,marhaba...silent subcriber nyo po ako sir...ask ko lng po sana kung normal lng po ba sa capacitor ng microwave na kung itest ko po sya good naman po pumipitik naman po...pero pag sa isang termal then yun isa sa body po nag cap may reading po mga 15ohms...sana po mapansin nyo ako...shukran thank you po sa pag response...
Wala po dapat continuity ang terminal to body ng capacitor.
Multimeter knobs position...?
आरे भावा मुजीक देवुन काय डी जे वर नाचायच आहे का ❓
Di mupo naipakita sa analog tester yong sa transformer po
What kind of tester is the second one used in the video?
It's an analogue tester.
@@chrisophertshabalala TYVM!
@@Brian-yz8dj KYVM. It's an abbreviations let me know its meaning please, also the first one is...!? 🤔
@@chrisophertshabalala TYVM = Thank you very much.
