make sure your key switch and feederhouse and seperator switches are on to get fan speed to work if you take the motor off to see if it turns it could be screw is stuck and pulling the motor down
We had a problem at the beginning of the season with the fan speed staying up on our 9410 in beans. Know what we did to fix itIJ Beat the hell out of that little motor that changes it with a hammer. Has worked fine ever since. It must have been stuck on that screw.
