Mine did the same thing. Look for them to be missing or not properly sealed. You can't see them but you can feel the escaping air from the blower and the out of place/loose gasket if you feel up there with your hand. Run the blower and start looking for air escaping from anything other than one of the actual vents. Jim 6147
