"220V Cooling Fan" damage arising from the use or failure is normal, in its blades turn no, we should how to fix it, here are several methods.
1, often caused by reasons not turn the fan blades, is the problem of poor maintenance. If the power is turned off manually rotating blades struck stiff, you should use some of lubricating oil dropped shaft, it can be lubricated, it will not affect the motivation to drag blades.
2, for the wear caused by "220V Cooling Fan" fan does not rotate, the easiest thing is to replace the parts, especially the sleeve, if the wear and tear easily burned.
3, if the capacitance decreases causing "220V Cooling Fan" does not turn, you can remove the capacitors, the same model for a new capacitor is recommended to select 20% larger than the original capacitance, will have a better rotation effect.
