1. Check whether the power supply of the bread maker is normal, such as whether the plug is plugged in, whether the bread maker is connected to the power supply, and whether the power switch is faulty. 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 plane responds. If there is no current and no response, it can be explained that the power module in the PCB board is damaged, which may be the part with strong current or the fuse on the PCB board. At this time, you can't repair it yourself. You can go back to the factory for repair or find a nearby home appliance repairman for repair.
