    Hello all.
    This is my first post, so I apologize for any irregularities.

    So, as in the title, the problem is that the refrigerator stopped working, a professional came and told me that the control module had fallen, I took it out and see that one of the chips is burnt, unfortunately so unfortunate that you can not see its numbers, I was at three "professionals", but everyone spreads their hands and says that without a number they can do nothing. My request is that if anyone knows what are the parameters of this transistor, I would ask and info (possibly a picture or circuit diagram), my gratitude will be huge. Burnt scaler marked in the picture. Whirlpool ARC 7558 / IX - control module

    Hello, I managed to fix it, I have the same problem, repair cost estimated at about 650 PLN

    Yes, the module worked, but it burned at every voltage stroke I exchanged it already 3 times (cost 3 zlotys), so I suggest to immediately connect the refrigerator to the surge suppressor (strip, filter). I did it and so far everything works.
    And so it is BAAAARDZOY THANK YOU for giving the number of this baby because I really pity to throw away a new and efficient refrigerator, and none of the few "professionals in which I was unable to help me and for them the only solution was replacement of the module.

    Do you have a photo of this tile from the 2nd page? I have a damaged item as an attachment ...

    This is a smd jumper.

    so I can replace it with an ordinary piece of wire ??

    You can, just look first for the reason why this jumper has evaporated you.

    the reason was prosaic I made a conclusion.
    unfortunately, after soldering the jumpers, one must look for further damage.
    But thank you very much for your help.
    greetings

    Electrolytic capacitors with incorrect parameters (dry) can damage the inverter. TNY268 can work up to 265 V, and I do not think that such large voltage spikes will appear on your network.

    Usually Koshiny are falling. Either a short circuit or a total loss of capacity. What causes the burning of the next elements of the power supply.
    Generally, the most common repairs are: TNY268PN, 2 * 22 µ / 400 (better give slightly more capacity than not too small), 1N4007 SMD, 10 Ω / 5W.

    I have a question, in which place this module is, in the aforementioned description should be fixed in the upper beam over the part of the refrigerator but it is not there.

    Well, I got it, today in the afternoon after almost 10 years of work, the fridge hit ARC7550 / IX and it with a loud slam :) after opening the controller casing you could feel the pleasant smell of the "magic balloon" that disappeared from the torn switch TNY268PN.

    Marcin, thanks for pointing out the cause of the explosion. The capacitors were easy to find (C13 and C32, 15 µ F / 400V). The diode and the power resistor are probably next to the C32 capacitor - therefore D1 and R42 respectively. Anyone can confirm this? R42 efficient (about 8 Ω no outlets), D1 also C32 theoretically efficient (14uF), C13 slightly swollen and at the outlet he hissed, leaving behind the leg in the PCB :) The other side of the PCB clean, no visible damage. Is it worth refining or replacing any other elements in advance?

    EDIT : After replacing U11, C13 and C32 refrigerator still did not get up. However, R42 was burned so that there was no trace on it except the micro-cracks on the underside, and I, at the beginning of laziness, did not desolder the resistor for measurement. Here's a tribute to Trull for a clue. After replacing the R42, the fridge came back to live and continues to work.

    Hello
    I just got caught up with this fault. In addition to the previously mentioned elements, I replaced the C15 capacitor because it was also swollen.

    The fridge is 10 years old
