If your Xiaomi Mi Ionic H300 has completely turned off, here’s how to reset it: Reset Procedure Let it cool down : Wait at least 5 minutes before restarting. The device has a thermal circuit breaker that cuts off power in case of overheating. Unplug the device : Remove the plug from the wall outlet. Plug it back in directly : Connect the hairdryer directly to a wall outlet (220-240 V~, 50/60 Hz) without a power strip or extension cord . Press the power button : The hairdryer should restart. The temperature indicator will light up blue (cool air), red (hot mode), or yellow (constant 57°C). If the problem persists If the hairdryer still does not turn on after 5 minutes of cooling down and a direct reconnection to the outlet: The thermal circuit breaker of this model is not automatically resettable - if it has been triggered, the device cannot be repaired by the user. Check that the voltage of your outlet is 220-240 V and the frequency 50/60 Hz . Contact Xiaomi customer service if the problem persists after these checks.

Q: Why does my Xiaomi Mi Ionic hair dryer suddenly turn off during use?

The sudden shutdown of your Xiaomi Mi Ionic H300 hair dryer is generally due to the built-in thermal protection system. This device has a non-resettable thermal fuse protection that automatically cuts off power in case of overheating. Here are the possible causes and solutions: Causes and solutions Overheating due to prolonged use - The hair dryer turns off to protect itself. Allow the device to cool down for at least 5 minutes before using it again. If the problem persists after cooling, the thermal fuse has likely triggered its permanent protection. Blocked ventilation - Check that the air intake and exhaust grilles are not obstructed by hair or debris. Clean regularly with a cloth, cotton swab, or toothbrush to ensure optimal airflow. Electrical issue - Ensure that your power supply meets the device's specifications: 220-240 V~, 50/60 Hz. Incorrect voltage can cause unexpected shutdowns. Thermal fuse permanently triggered - If the device does not restart after 5 minutes of cooling, it means the non-resettable thermal fuse has permanently cut off the safety circuit. In this case, contact customer service. Tip: To avoid repeated shutdowns, use lower temperature settings (Cool mode or constant 57°C) instead of continuous Hot mode, and allow air to circulate freely around the device during operation.
