So I just cleaned up my Dirt Devil m08510 after replacing the fan, I checked the motor too as the last time I used it, I heard a clicking sound even when I want picking up anything. Now I put it back together., and the I hear an electrical buzz followed by the motor slowly turning. I’m concerned that the little white adhesive seal behind the fan is not permitting free turning of the fan, the carbon brushes are bad, or one of the screws are too tight. Any ideas? I’d hate to throw away such a rare vacuum over a simple fix!
