Hi all. I have an 8 year old xxv and in the last week the blower fan/distribution fan has been acting wacky, doesn't seem to always want to blow at high speed where I almost always keep it set. Everything is original, never needed to replace anything. Now the fan is intermittent in speeds and fire goes out after about 15 mins. I've ruled out most obvious things. ESP is clean, took back panels off and looked at distribution blower had some minimal dust etc but vacuumed good and it spins freely. fines box is empty, ran in test mode and no indicator lights come on. The door seal is matted pretty good and I've noticed this season I do get a light smoke smell during lighting phase. I have ordered a new rope/door seal because that needs to be done, did the dollar bill test and it failed in a few areas. So could it be the leaky door gasket doing all this or is the distribution blower def bad? Where would you suggest getting one, ebay seems to have them for around $129? Any other suggestions would be appreciated or perhaps I just need to go ahead and get a fan coming? Thanks..
