Good afternoon everyone, again here asking for your knowledge to repair a microwave oven that does not turn on the card when I speak the door turns on the spotlight the fan and the turntable but the card does not give a sign of life it should be mentioned that I already checked the Door switch and the source voltages and it seems all right just that it doesn't turn on anything if someone could guide me about what it could be. Thank you in advance and greetings to all.

Hello, check that the transformer is giving the voltage in the secondary, to power the card.

How are you, thanks for taking time to help me.
It does not bring a transformer it brings a switched source at an output of 7.59 v and in the next 12.21 which suggests that the voltage is fine

Well then you have to have the voltage of 5 or 3.3V that feed the mic, is that voltage?

Yes
is not 5, 4.90 are coming I think it is enough to activate the micro

If it is ok, if the microphone is powered and you have nothing on the display, or the microphone is not oscillating or is damaged, it would have to be fixed if you have glass to change it to see what happens.

As I told you if the microphone receives the voltage of 5V and nothing works, it is likely that the microphone is damaged.

Yes, the total functions will be similar since several microwaves are very similar, always talking about the same capacity.

Hi.
But if you turn on the light, the fan turns on, and I suppose it should heat up even if you don't mention it, the mic has to be working. In that case it may be a failure in the display or other peripheral.
Also check the electrolytic capacitors.
Regards.

I already went crazy this oven brings a resistance inside it is the first one I see like that with steel inside and all that you comment on the light the fan and the turntable rotate although without the card, the card I am testing it out of the oven precisely I removed it to check faults in the switches but they do not present faults I don't know what to do but what if the card should turn on outside but does nothing.

But the card has to be connected, by the switches if not it will not be activated unless you make a bridge in the corresponding place.

Responder

It has a switch that is the one that feels the door open and closed the other two interconnect each other to make the fan feeder and the rest

Responder

The one who feels the door has to be in position to be able to test it outside.

Responder

This is how the switch has the test card installed but nothing even lights up a life signal

Responder

That's right, check the entire card and if it is the mic. But now the problem is that no card matches, this panel does not bring numbers only selectors I will have to look for the original card

Responder

I still have the fight to find the card or the microphone even without news
