We've had the 42 Apex from Fireplace Xtrordinair for 4 years and the blower started getting loud the end of last season. I removed it and cleaned/lubricated it but after 2 months, it's noisy again. I only found one place online (stoveking.com) that sells the listed model and the price is over $400. It's a 400cfm convection blower part #250-04176. Is there a recommended place for blowers and/or an option for refurbished blowers or getting it reconditioned? Or maybe a comparable model that can be fitted?
