1. In many cases the reasons causing the blades do not turn the "Tiny Cooling Fan", 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 non-rotating blades abrasion, the easiest thing is to replace the parts, especially the sleeve, if the wear and tear easily burned.
3. If the capacitance decreases causing "Tiny 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.
After much of a problem adjusting shims 4. shaft axial clearance can choose disassemble the motor. But I remember back when the motor is installed, you must pay attention to the rotor and the bearing concentric, lubricating screws diagonally slowly tightening, and finally with wood to knock on the shaft to make sure it concentrically. Remove the motor is very easy, but putting it back is difficult, do not casually, it will be very easy to repair bad fan. If you find that when removing the motor bearing wear serious, it should be for a new part.
5.If "Tiny Cooling Fan" because an electrical fault, you can check the wiring of the lines, sometimes damaged wires, can fix the issues.
