my fan stopped working again, last time it was the resistance that was broken, this time the fan wasn't spinning free, so i opened the whole thing,SUPRISE , al the magnets did come loose , wich fucked up my resistance again to !! i putted some glue on the magnets and adjusted them again on the original place, after 24 hours i asembled the whole thing again,installed a new resistance, and my fan is working like a new one, at no cost !!
