If the fan does not run the fan motor may be burned out or worn out. The fan blades should spin very freely, if the blade doesn't spin freely the fan motor should be replaced. If power is getting to the fan motor but the fan motor still does not run, it may be burned out. The fan motor is not repairable, it will have to be replaced if it is defective.
