Hello, everyone, today i teach you to fix this electric pottery. Its failure manifests itself as a normal turn-on, but it automatically turns off as soon as it is heated。
When the panels are removed, the curtains are shown in these parts. The electric pottery said it was an electric furnace, with a panel and a control circuit. This is the 220v input end, this is the electro-hot wire plate, this control panel, this is the temperature switch, and it regulates the fire power of the furnace。
This is the main plate of the electric pottery, where the heat fan is here, where it's a hot spot, where there's a temperature fuse, and where the temperature insurance breaks off, it's not hot. The middle of the stove is a thermoelectric doll, and the two are its connections, and this is the port of the dispersing fan。
The fan won't turn after i plug in this pottery. It's always black and red. If there's a straight flow of 18v, it means the fan's broken. If not for 18 vs, it is either fan-driven level 3 tubes or the electric capacity to charge it。
After a check-up, the problem of failure cannot be ruled out. If the chip is good, the encoder is broken. The breakdown of the encoder would result in the chip not producing the correct wave shape and thus not working properly. The chip is not working properly, so the fuse cannot heat normally. As long as the encoder is ignored, the measurements are normal, but they are not hot。
So, you remember, this malfunction, the good or bad encoder, the good or bad, and the problem is basically solved。
I'm a nut, watching me, teaching you the most useful maintenance techniques。
