24V DC Cooling Fan repair method

Often cause "24V DC Cooling Fan" fan does not turn causes problems are poorly maintained. If the power is turned off manually toggle stiff blades rotate, you should use some lubricant drip shaft, it can be lubricated, it will not affect the motivation to drag blades.
