Why does the fan turn on after the induction cooker is powered on?
If it stops, the internal electronic component is protected by heat and power off, such as a wire plate thermistor. The resistance is controlled by temperature. According to the different temperature, your cooker at a certain temperature, it will not stop, until the temperature rises to the set temperature protection when the thermistor becomes infinite, power-off protection, then the fan will stop.
This phenomenon is normal, because the electromagnetic furnace in the process of operation will generate a large amount of heat, and the heat radiating block electromagnetic oven on the circuit board is unable to effectively discharge the necessary auxiliary cooling fan through the rapid discharge, so that the internal electronic components to work properly.
In this case, the fan drive circuit is faulty, that is to say, the drive triode is broken down and the fan is in the condition of long power supply. The way to deal with this is to replace this triode. Usually located in the fan socket, you can find this triode, remove the model of the pipe to find a replacement, you can pay attention when you install the new pipe, do not adjust the wrong foot on the line.
