Microwave oven

microwave bgh quick chef 16600 does not heat

Hi how about, I bought a microwave bgh lights as normal, but it does not heat anything, when I uncover it turns out that the fuse was blown and was also bridged. and also the capacitor did not explode but left a black mark under the plastic and on the lid. probe the capacitor is 0.95 uf and the tester gave me 0.94 uf and I also tested it with the bulb and turned on half the intensity of the light, (it means that it is ok). I don't know it could be.

it's the image of how the capacitor was

first change the capacitor second measure the magnetron if it is not derived amaza and check the transformer too and the diode

try the magnetron, with each leg and does not give mass, then look for continuity in the 2 legs and neither. in this model you cannot find the diode,

if he didn't give you anything on the legs then the magnetron is open is bad

Friend if you measured the capacitor with a bulb should not turn on half its normal brightness, the correct thing is that just turn the filaments, in the magnetron terminals you have to have a coil resistance if it is not open. I recommend you check each component of the electrical circuit since there is the problem and finally eliminate that bridge due to its fuse, luck

I measured the magnetron in ohm scale and it gives me 000 (infinity), I take one of the legs and measure it with the sheet and nothing happens the tester shows 1, the same with the other leg. And so until trying all the omh scales in the multimeter, now with the capacitor it is a case because despite leaving some black under the plastic I measured it and with the tester in Uf and it marks me 0.94 (it is 0.95) and with The bulb works too.

Then check that the magnetron does not have physical damage such as broken magnets or that the housing is not flamed, and if your capacitor is well check the diode, or disconnect the magnetron from the electrical circuit and start it, if by putting it to work with the magnetron disconnected there are no strange noises or anything else out of the ordinary as smoke effectively mind is your magnetron who is damaged and replace it luck and comment

I want to add, that apparently the microwave had already had a fault, because where it had to be a high voltage diode is not.
they only put a direct cable to the sheet (https://ibb.co/Qv0tWVR), the diode apparently exploded and spotted the fan, not the capacitor
(That's why the measurement was good https://ibb.co/VBc0mHH)
and well the 10A fuse was blown too
what could have failed? so that the high voltage diode and the 10A fuse have blown?

then the magnetron is bad open

Maybe only the diode was short and that caused it to burn then place a diode and if it does not heat also buy the magnetron

Tomorrow I buy the diode and today I see if the magnetron has cracks or something. (I tried it and the measurements are good for me)
why could the diode be shortened?

I do not know exactly but every component has to be damaged at all times everything to serve is over, a tip the tester itself will not always detect the failure of a magnetron since it only detects if one of its terminals is grounded or if between its terminals not There is continuity, if not, you have to check your physical condition in detail because a magnetron that is damaged with one in good condition also in most cases have continuity in its terminals the difference is that the damaged one has broken magnets, etc. luck

I already fixed the microwave oven thank you very much guys I tell you,
At first he believed that the microwave had the capacitor left and it was not like that, it turns out that the microwave probe was bridged in the fuse and where a high-voltage diode was going they also made it a bridge. That is why it did not heat, it turned on nicely, but when it was marked towards a strange noise and did not heat. In the end I put a fuse of 10A 250v Fast cut because they did not have the common and a universal diode

The capacitor I have is a Samsung of 2100w 0.95uf
and ready it worked great
