So I've got a fan that needs to be replaced in my 5100i. I stopped by my local dealer but no one was in (I guess because it's high summer) so I did some on line searches when I got home and the prices I'm getting are right around $140 or so not including shipping (Blackswan and somewhere else I think). One of the online dealers had a pic of the fan and it's a Rodale AC Axial fan, part number FP-108-1. I've taken the bad fan out of the insert and there are no model numbers or any other product info on it but it looks to be the same design and material as the pic of the replacement fan on the on line dealer web site. I researched the manufacturer and part numbers I took from the picture of the Quad fan at the on line dealer and have found a source for the same model at several different places on the net, prices range from $15.95 to about $25.95. So I'm willing to take a gamble on the $15.95 plus shipping for the fan available through a non-stove dealer.............but wanted to get a reality check from you guys first before I pulled the trigger. Is there anything I'm missing or not taking into account?
