Greetings to all.... I already fixed the problem, it was the R38 resistor, I looked for its replacement and eureka all functional again. As suspected, in R38 there could not be a short 1 honm is sufficient for the current there. Thank you for the support provided

So I'm going to look for the resistance that goes there and test

Q2 is a triacs below attached datashet [ATTACH]n3449335[/ATTACH]...

Check the resistor with the lighter and if it rises values in minivolts, that is to say it is fully functional, the R38 resistor was smd and its code was 1R00 which in the smd code tells me that it is a 1 ohm That's why I joined the connection with a cable, is that why?...

Hello everyone, next I have the following problem with the Sumsour 8586D 110v dual station I bought it a year ago and it worked wonderfully, now it presents the H-E error on the soldering iron side, the hot air side works correctly..... I disassembled the soldering iron head because the manual tells me that this error is due to ceramic resistance problems, in effect, I measured it and it is open, I bought a new one that is working verified in a soldering iron and nothing.... The same error continues, I proceeded to open the station and check visually, I found a totally damaged 1R00 surface mount...
