Ohne Worte, leicht zu verstehen wie Bauteile einer Mikrowelle geprüft werden können. Klasse!

[@wannabe8x6]

Great job, most comprehensive easily understand video

[@nachovelino]

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.

[@nigelmitchell351]

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.

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

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.

[@lillyminutolo5716]

Does it works?

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

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

Can we use any side for diode

[@fffinga]

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?

[@protechelectronics79]

Try to change new magnetron.

Sa digital wala po talagang reading pero sa analog may mareading pero sa high resistance.

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.

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.

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.

Sir kapag OL or open yung last test mo sa hv xformer may prob? dapat ba at least nasa hundred ohms yun?

Yes po

I think the "symbol" of the diode is inverted,
But the measurement is correct.

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

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...

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.
