The reason why the flexible induction heating coil is burnt
The possible reason is that the quality of the heating plate is not good, the aluminum heating plate, and the insulating paint of the heating plate are burnt, and the use time is too long. These will greatly reduce the heating efficiency and will expand the scope of failure.
Several reasons for the burning of the heating plate of the induction cooker:

When the pot is empty, the heating is not stopped in time, which may be caused by the decrease of the internal resistance capacity in the detection circuit
The temperature sensor in the coil of the induction cooker has undergone qualitative changes, the resistance value fluctuates, and there is no command to stop heating or there is no thermistor
Alternating current enters the inside of the coil, causing the coil to heat up and turn black. -The general reason is caused by the short circuit of the inductance coil
The universal board is replaced, or the overall quality of the circuit board inside the induction cooker is poor. The heating is slow, and the heating coil works for a long time to form the existence of black shadows.
If the black shadow of the coil of the induction cooker is not serious, it can be washed off with water and dried or dried in the sun, and then it can be used after being dried with some insulating paint. However, it is recommended to replace the heating plate directly. There may be a short circuit inside the coil, and the current will increase greatly, and then the insurance, rectifier bridge stack and IGBT power tube will be burned. The gain is not worth the loss, so it is better to replace it as soon as possible.
