I used one AA battery and took two wires from it to the two solder points on the fan. Impeller did not move (it was a little difficult to hold the wires to the solder joints and look at impeller at the same time).
Did not hear anything either. Did same with two AA batteries in series. Nothing.
Before I did these tests I made sure I got a proper reading of the two wires so I knew they were contacting the + and - of the battery (batteries).
So impeller/fan = motor. It must be a bad smoke motor, right?
