I have a 2011 3450TS and the ceiling fan just does not put out any air. I have change the rotation that the fan turns and it make no change. It appears that the blades just do not have enough pitch. Is this a common thing in this unit? I the previous SOB I owned it also had a low profile fan, but it actually worked. I really hat to have to purchase a replacement fan. I currently have my unit at the dealer for some warranty work and did bring this issue up. I did the same thing in in July and the service response was that this fan just did not work well.
