Mabe selenoid washer card G15

I have a problem, the washing machine came because of a sensor failure since I was not doing the washing cycle. I changed it but at the time of testing it starts to move the engine but it does not activate the selenoid I was testing the card and the orange circular fuse that has the card was burned probe by placing another and just connecting the washing machine burns it automatically. Test the mosfet transistor that it brings to activate the selenoid and mounted it marks me an abnormal reading. (I HAVE ANOTHER ID CARD FROM ANOTHER IDENTIC CUSTOMER AND I WAS COMPARING AND WHEN I TESTED THE DIODES, I AM CHANGED BY PROMANDING IN BOTH POLARITIES. the selenoid What I think is that something is short but I really don't know that I've tried everything. Help please I need to solve

Comment card registration .... Verify that the solenoid has 145 ohms ... see this document ... https://drive.google.com/file/d/1cmJXfgxhML3GdZqOCvVEiZJ6vo3rsUFy/view? Usp = sharing

In addition to writing and sharing with you, check the wiring .. Although I already suspect a problem with the card .. Always disassemble a terminal when measuring each period. Regards

I already tested with a functional card and the normal active selenoid with the other card does not show me that fault. But I really do not understand that the diodes are already disassembled and they are good as I say I just change that fuse I just connect the washing machine and it goes off in a short time the fuse fires and at the terminals of the diode (Where they are mounted) There is a resistance that on the card That is good there is not.

I require card registration ... Otherwise, we would only be guessing, where you will have to check ..

Well, I have no doubt that the MOSFET is damaged, I also believe that one of the diodes is damaged, so, remove the MOSFET and measure it externally, proceed equally with the diodes.

Can you tell me what the correct reading of the mosfet would be.

Watch these 2 videos to clarify the picture, about Moset measurements.

ready and check the mosfet is badly damaged I was looking at all the stores in my city and nobody owns the component will there be a way to replace that component with another more accessible?

Good afternoon, effectively disassemble the diodes and 3 of the diodes mark me continuity (Bone testing diode) marks 0.00 in both polarities only one reduces the voltage to test it. The question now I need to change the mosfet or just change the diodes.

Most likely, the Mosfet is also damaged (place an IFR840)

These are the right replacements .... P6NA60
IRF830,
IR840,
IRF740
Or the latter, IRF850 .....

One of these 2 is your mosfet .. the difference is only that one is SMD and the other is not ..

Well, we only have to wait for results once the new devices have been cloned.
Remember that you can replace the diodes with 1N4007, the ideal is that you replace the 4 ..
Do not go wrong installing one upside down, well .... you will damage everything ...
Greetings and I hope to have an answer that will be satisfactory to me!

I was able to locate the P6NA60 and the IRF840 but I could tell that they are not superficial mosfet in that case as I would do with that third pin, in the case of the P6 it comes with the plastic top contact ..

I explain the IRF840 is not exactly a shallow mosfet the diagram is similar but it brings 3 pins down and the top one would place it the same without placing the middle one, right? above

I do the test with this and it doesn't open the gate in the same way: C

The central leg and the metal backrest of the mosfet ARE THE SAME .... Now I had already sent you the address of Mercado Libre Venezuela, for the purchase of the exact component ... https: //articulo.mercadolibre.com .ve / MLV-502132344-03n60s5-spp03n60s5-cool-mos-infineon-power-transistor-_JM ... Maybe you have damaged it, I don't know, but you have to measure the ends of the mosfet and indicate measurement, then you reverse the tips and measures and comments ... I think it should be between 1.10 v and 0.9 v ... installed but de-energized the card, If it gave you values of 0.00 already "passed to a better life" (heh, heh, heh)

I bought the IRF840 at a store since the free market had no personal deliveries. Do not directly mark 0 bone if we look straight ahead as proof there in the video. the right leg in positive and the middle one in negative is always marking bone if it marks well but I try exactly the same as it is in the video and it does not mark I have not mounted it I was even testing it as well as I bought it.

You mean this video? .In it he shows you how the shot is activated and how it is “shut down.” ... https: //youtu.be/1Q64AlahOkA

Responder

Exactly in the IRF840 I test in the same way as it is there in the video and it does not activate or anything then I invert the positive in pin 3 and mark it with the one above the drain and mark the diode but it is always active. so I really wouldn't want to ride it like this since I see that it doesn't do the same function by testing it below: C

Place only one end of the tester to “short circuit” G and D (gate or gate and Drain or Drain) to “eliminate shot and therefore once done, the reading that worries you will be removed.
