appreciate the help Stephen. Good advice on the speed control. Don't think were happy with fan at full speed. Now , I should say that the new fan motor is somewhat different than the old, and required a different bracket and hold down. Don't remember seeing this control but will look again. Is the speed control change pretty straighforward? Out with the old in with the new? Any one that can give a specific direction, or how to please advise further. and thanks.
