Microwave oven

micro wave does not heat .. DAEWOO KOR-9GDB

Good morning friends of I repair. I have problems with my microwaves, I stop heating it, I checked it and the input fuse burned every time I put it to heat. the magnetron connector was terrified. I did a job and the probe started well and the fuse no longer burns. But it does not heat. They could guide me to see what happens. There I leave an image

I already did it and it's fine. He is not terrified. There is continuity between the filament but not with the chassis .. change the diode and the condenser and it remains unheated. But the traffic warms up, I don't think it's normal

Check the magnetron, this should not have continuity between the housing and the connectors, the magnets should not be broken or with game, luck and comments.

With the tetser based on ohms, the following measures the primary connectors of the transformer. Measures the secondary between the secondary connector and the base of the transformer. You have to scrape the base to remove the varnish a little and that the metal in sight then measures the cables that go to the magnetron and tell me the results of the 3 measurements

Check the tip of the magnet. It must be bright and without carbon or puncture. On the other hand it cleans the interior well. It has to be clean without food debris. If there is rust, you have to paint the interior with epoxy paint.

I already checked it. And I cleaned it well. I look like new.
I tried it again and it still doesn't heat

I suspect that the HIGH VOLTAGE fuse is 100% damaged. and that is why voltage does not reach the magnetron filament, do it and tell us later. because you apparently changed other things! you also say that you removed the SHORT from the capacitors that are normally DAMAGED and send the voltage to ground and the magnetron does not work = MOST CASES

The thing is that this micro does not use fudible of hv only has the input the output cables of the traffic reach the capacitor and magnetron without fuse so it has me crazy already.

Then the card may not send the pulse to the transistor that controls the RELAY that is responsible for turning on and off the high voltage TRAFO that sends HT to the magnetron, I regret to have responded so late for not going to the forum. I hope you have solved the fault because by removing the internal capacitors from the magnetron you will recover the magnetron, in fact I have recovered several like this and they work perfectly without problems, you just have to know how to do it and ISOLATE very well so that the voltage does not land on the chassis or box.

After doing everything that the colleagues indicate, it is worth noting that the magnetron contacts, perforations, inflammation or different color have no indications of carbon. This takes it short and cancels the heating as well. and that the transformer heats up ..... well it works with 1kw or more so it must heat because 1kw cannot go uncovered either by the thermometer or the domestic energy meter

Hello friend, you say you changed the line input fuse, but if the magnetron filament was terrified, it sure burned the high voltage fuse, which goes in series with the filament feed, inside a plastic case. Check your status. Comment results. Cheers !

Friend, the fault is obvious, it replaces the magnetron, if at any time it was short to ground it is because it is damaged internally even if its filaments give cotinuity, he says, greetings!

Hello greetings as the colleague fermin says that failure is the magnetron The first thing that should have changed was the magnetron get one who knows that this beno and places it and will see that it solves the fault greetings to colleagues. Atte Hector of Venezuela
