If the device does not work, please refer to the following troubleshooting steps:
1. Check whether the power supply is normal or whether there is a power outage, blown fuses, unplugged or loose plug during the use of the hair dryer;
2. Check whether the voltage at home is too low (below 187V);
3. Switch off and unplug the device to check whether there is any matter in the air outlet;
4. Due to the air outlet being blocked and other reasons causing the working process doesn’t work. The hair dryer overheating will automatically turn to the cold air and then restore the hot air after the machine cools down.
