We have a 2011 Big Country 3450 and the fireplace fan will only run for 2 minutes and then shuts off. My dealer has told me that it needs a new part(don't remember what they called it) and they are waiting for the part for two other units as well. Anyone else having fireplace issues? It has been almost 3 weeks and no parts yet and they are claiming its the factorys fault. They have known about the problem since last October!
