At the end of winter our stoves distribution blower started squealing. To get thru the rest of the season, as long as we kept the fan at the lowest setting it didn't squeal. We need to get it replaced before Oct 2011 because it will start getting cold and because our electrical warranty will be up then. Our dealer charges at least $150 for the house call. Does anyone know what the cost of the fan is and has anyone changed it theirself? We are not very "mechanical" and I'm concerned about doing it right but don't know how easy or hard it would be to try. Do we need to order the fan thru the dealer?
