Use a long "Micro Cooling Fan" did not turn up how to do, first of all look at the motor lubricating oil is there, if the motor lubrication is not, generally have noises coming out, more serious is the fan does not turn. In case of power failure you move a hand to pull the blades, the fan will be a little stiff.
"Micro Cooling Fan" Repair Methods: In this case just add a little oil to the motor on the line (if it can not find oil, vegetable oil used at home is also possible.
In most cases we may all encounter the following phenomenon, "Micro Cooling Fan" did not turn up, you move a hand to pull out or to wait a long time will slowly turn up again after a period of time to find a hand to Stubbs would not move. This phenomenon is most likely reason is that the start capacitor smaller fan inside, enough to make motor rotation.
Maintenance: Replace the capacitor "Micro Cooling Fan" inside, we can see the capacitor after removing the fan motor housing. We can replace the same specification capacitors, capacitors may be a little larger than the original (not more than 20% of the original capacitance).
