Whole House Fan

 I removed the vent in the ceiling, and fiddled a bit with the exposed fan, and now it spins. I'm not sure what I did to fix it. There is a 3 position pull chain sort of hidden, and I set it to the fast speed. We are due some hot weather this weekend, so a working house fan is good. My plan is to run it in the morning to draw cool air into the attic, then in the evening. 

Editor's note: Two days later the fan failed. But after resting a half hour, it works again. I guess I need to test the capacitor and motor.
