I have gotten to the part of the installation to where I have attached the ceiling fan blades. Before the blades were attached, the motor worked and rotated just fine. After the blades were all attached, they will not rotate and the motor will no longer rotate. I have checked everything, also including the things the manual has listed on the trouble sheeting page. Do you know what else could be wrong and what I need to do to get it to working? I would appreciate any help I can get. Thanks

Check all power connections and make sure motor rotation switch is in one position or the other, it will not work if it is in the middle.
