Dryer making noise and was terribly weak blow. Open it and look at what it was.
Fan filmed. One can see the motor mount and its axis.
In general, hair dryer disassembled, inspected, nothing looks broken or defective is not found. He pulled out a spiral, even the motor disassembled. Replaced the electrolytic capacitor.
It turned out that the fan was slipping off the motor shaft and rub on the rear housing.
In the central hole axis of the fan slipped gum as a sealant and put it on the axle. Fan ceased to move out, and a hair dryer continued to work properly.
Was very simple, but to understand it took to sort out almost all the hair dryer. Not always passes repair "shortest route".
