I’ve had my Absolute 63 for a month now and it’s been great! Two days ago it developed an extremely loud noise, rotational impact noise. I narrowed it down to the combustion fan. Looking further I found the fins on the combustion fan cracking and hitting Phipps screws that are right underneath the fan. The store I purchased the fan from wants to send me a new fan, ok great. I do feel some play in the fan motor but I don’t feel it’s enough to actually cause the blades to hit the screws. It seems like a horrible idea to have screw heads right below the fan. Seems like the fan is just failing to me. Is this going to be a maintenance item every 1 ton of pellets? Is this a known issue? Should I request a new combustion motor? Just for the record I do burn a 50/50 mix of pellets and corn. Would this have an effect of the fan blade life? Thanks for all and any input!
