Why change thermo actuator and blocapuerta next to platelet?

If testing the block and thermo actuator work well, why should we change them if the platelet broke? What is the characteristic of these components that causes the platelet to be damaged? Thank you.

4 Proposed Solutions

Hello, they are changed as a precaution since they are components that, when put on short, ruin the plate, if you put a new plate the other components already have use and we do not know when they can fail, it is also cheaper to change block and thermos than a plate, greetings .

    This is a good answer. I didn't understand why a bloca and a thermos that work well could have burned a plate. I listened and read a lot of times that "the plate burns for a reason, then you have to change also block and thermos that are responsible." In my case, those components work well, but not the board. Thank you.

Dear, I think there is an error. The suggestion of replacing door block and thermo actuator is when the triac "Q3" is damaged on the board, which controls these peripherals. Said triac controls these two peripherals next to the drain pump. Regards

    I also tested the pump and it works well. If the triacs are damaged, but I test those components (block, thermos and pump) separately and they work, should I change them anyway, next to the triacs?

    Dear, the triac is replaced if it is damaged. The suggestion of the replacement of the two components mentioned above is because in the live tests you cannot determine what the consumption of them is and the triac can only handle a few milliamps. Regards

    Very good answer. I have some small adhesive heatsinks. Would it be a good idea to put them in the triacs?

    Dear, the only triac that usually causes problems is the number 3. It can handle about 600 milliamps, consumption higher than the pump, block and thermo actuator together, when they are well. The issue of live tests is that they often exceed this consumption and cannot measure it, which suggests that they are well and when placed in place, lead to the deterioration of the triac. It is from there the suggestion of the change, although direct they work well. Regards

SOLUTION ACCEPTED
a block and a thermo-actuator, any of the two, that the triac Q3 or its resistors are on the board, with a tester, measure the same (ohmiage) as a new block and thermos, even if you test it directly (obviously assuming this that these devices do not have kemados pins and that there are resistances) work well, BUT WHAT HAPPENS ???. For that we must apply the law of omhs, the current is equal to the power over the voltage and the current is equal to the voltage over the resistance, the triac is manufactured to handle a certain intensity of amps, if in these two components, there is an excessive consumption (amperes) that exceeds what the triac handles, the latter will be kemara or cross. You will try them with a lamp in series to the block or thermos and you will see that there is no short, but what you do not see, is the consumption / hours or amperes / hours, that's why technicians change them, for precaution and so that there is no headache, since its cost is not high enough to replace another plate

    Interesting. Isn't it better to bypass the door block to prevent this component from damaging the board? There are no pets here that can open the lid.

    obviously, I do, but if the client wants to have the lid locked, because he has small children, what would you do ?????

    I know what the blockchain was invented for and why washing machines cannot be manufactured without them. I was struck that the fact that you have to change the door block if the corresponding triac is burned is highlighted so much in these forums. That is, if the first symptom that the door block is bad is that it damages the plate, I prefer to eliminate it before it does. Thank you.

Hello champion, the door blockers are integrated and the thermo-actuating tablet does not come, that's why everything is replaced and ready

    Thanks, but I still don't understand. They always say that the two components are responsible for burning the platelet. I never saw why this is so, nor why I should replace them if they "appear" to be doing well.
