1. Check whether the power supply is normal, whether there is a power outage, circuit fuse fuse, plug not plugged in or loose during the use of the hair dryer.
2. Shut down and unplug the plug to check whether there are any foreign objects entering and exiting the trend. Foreign objects entering may cause the hair dryer to fail to operate.
3. If there is a non-working phenomenon during the working process, it may be due to the hair dryer entering or leaving the trend blocking, etc., causing the hair dryer to overheat. When the hair dryer overheats, it will automatically shut down for protection. Guide the user to clean the filter, let it stand for 5 minutes, and then restart the machine to use it. "" "
