1, check whether the power supply of the bread maker is normal, whether the plug is plugged in, whether the bread maker is connected to the power supply, whether the power switch is faulty, etc. If there are no problems, you can continue to the next step.
2. After plugging in the power supply, observe whether the power indicator light on the charter machine responds. If there is no power supply and no response, the power module in the PCB board is damaged, or the high-voltage part is damaged, and the fuse on the PCB board is damaged.
