If the negative ion hair dryer fails, do not continue to use it, ask a professional to repair it, or take it to a repair shop yourself. But before repairing, it is best to understand some of the hair dryer failure repair methods, so as not to be fooled by the maintenance personnel and spend a lot of money. How to repair the negative ion hair dryer?






1. No hot and cold air: The hair dryer does not have hot or cold air. The reason may be that the button switch spring is not working or burned. You can adjust the pressure position of the spring with tweezers, and clean the contacts with a small amount of alcohol. If the spring plate is severely burned, it must be replaced with a new one.


2. Insufficient wind power: The cause of the failure may be the short circuit of the motor winding of the hair dryer, the wear of the oil bearing or the loss of oil. It is necessary to replace the new motor and inject an appropriate amount of oil to eliminate the failure.


3. The motor does not turn: the motor is an important part of the hair dryer. If the motor does not turn, it may be that the motor carbon brush is in poor contact, the ventilator is stained with carbon powder, and the capacitor is short-circuited. Repair and replacement are required to eliminate the fault.


4. Loud noise: The cause of the fault may be the wear or vibration of the bearing of the hair dryer. As long as you replace the bearing with a new one or add an appropriate amount of oil to the bearing to make it run smoothly, the fault can be eliminated.
