Recirculating fan or exterior venting? Is is the exhaust system overhead or downdraft? If its exterior venting, does is vent to the exterior? Or terminate in an attic area under insulation? If its exterior is the stack blocked? Or blocked at the damper if its through the wall? Does is have screens or filters?
As for blades, fan blades are fixed and shouldn't move. What blades are you talking about?
