Plugged it in and turned the switch to "on" and nothing. Dead. No hum, nothing. Someone on another page told me to check the impeller. I stuck my hand into the hole, but I only feel a small round knobby thing that doesn't move. Is the ball part supposed to move or what exactly am I supposed to be trying to turn? Please tell me this won't be hard to fix. We've only had it for 3 or 4 years. But I made the mistake of not taking it apart and cleaning it before winter and storing it in the barn over winter. Ugh. Hope I didn't ruin it.
