Electric fan has abnormal sound how to solve?
1. Lack of oil. Although many electric fans do not need frequent lubricating oil, and rely on electric power to drive, the need to use "oil" is relatively small, but the outer ring of the electric fan generally has a small bearing or sealing shaft connected to the fan head, if placed in the warehouse for a period of time, there will be rust or dust, and there will be "sizzling" when used. Solution: In this case, you can not open the protective cover of the fan, you use a chopstick or a wooden stick, dip a few drops of oil on the root of the shaft.
2. Deformation. In addition to the lack of oil in the shaft, there are two situations that are more special, that is, the fan blade or protective cover deformation, the fan rotation will produce centrifugal force, and the protective cover in addition to protecting children or users accidentally touch the fan injury, but also play a role in isolation, because improper use will cause the fan blade screws loose, protective cover deformation, when the fan rotates, Sometimes there is an unusual sound of wind and banging or rubbing the protective cover. Solution: In this case, you can remove the protective cover and fan blades, clean the ash, dust, correct the shape, and then re-tighten it, there will be no "sizzling".
3. Wind the string. Now most fans are electronic, can be neutral fans, but the old fan timing needs to be "wound" first, some washing machines, watches will also be applied to this principle, after the full string will issue a "or sizzle" sound. Solution: If it is this kind of winding electric fan, the "sizzling sound" is normal, because after winding, the fan begins to turn, and the internal timing device will automatically reset, and the reset process will emit a sizzling sound, no maintenance or treatment is required.
4, the loose fan blade on the bearing and bearing wear lead to greater clearance. Solution: You need to remove the fan and tighten the screws so that after it is firmly fixed, it will not vibrate again.
5, screw loosening: the screw at the fan shaft is loose. Solution: Tighten the screw.
