Samsung microwave, magnetron perforated

Hello friends of me, I noticed, this Samsung microwave model MG9696W arrived at the workshop, which did not heat, it smelled of burnt plastic, with slight visible smoke, when opening and checking it I found that where the voltage that comes from the capacitor is connected, just in the plastic connector where the 2 connection legs appears, there is a small visible perforation, and with the smell of burning, I ask is it possible to review it, proceed to cover that hole? has anyone happened to it? thanks for your clarifications friends, greetings from Ecuador .

Colleague just change the magnetron the diode and the capacitor is rare to suffer change the greetings.

good afternoon, the magnetron is damaged you must replace it, it is sure that the internal magnetron capacitors will explode due to the high voltage, on the other hand it evaluates the state of the high voltage capacitor and the diode, to verify that they have no damage

Thanks Nestor I will and comment

by the way take the tester and put it in cotinuity and measure the two disconnect pins of the magnetron must have continuity 0001 and then touch a tip of the tester a pin and with the other to the metal chassis of the magnetro if it gives you continuity this toltally damaged

Nestor, I agree with you that the Magnetron is damaged and that when measuring resistance between any pole of it to ground, if there is continuity it is more than unusable. The only detail is that there are no capacitors inside the magnetron, it is as if it were a bulb without a glass bulb: it serves to accelerate the electrons inside it through its cavities (it does not store them, which would delay them) to take them to the antenna and exit to the oven cavity, which is like a waveguide.

You know friends the tester making tests comes from continuity as colleagues say it is very bad, half traffic is ok, half capacitor is ok, I just doubt with the diode, in x10k, with multi analog one side marks, the other does not mark, the other multi digital I got it damaged hehe

you must change the magnetron

I use a homemade 12 volt source applied with a led diode the diode of pessar always does the same thing only allows the flow of current in one direction, I put it and the led marks me consumption and I put it around and I do not mark consumption because it does not allow flow

Hello greetings friend, it is best to replace the magnetron I have reached the microwave many with this type of failure and the solution is to replace said magnetron with an equal one if you can not place a similar one that meets the characteristics to the original for example 1 that the fastening holes match for mounting. 2 that the aluminum fins remain on the fan side. 3 that the tip or antenna is equal to or shorter than the original but not larger if you could not touch the chassis and you would damage the magnetron greetings a hug.
