I’m new to wood burning and we are loving our new Lopi Revere and the blower (~15 fires so far). I’ve read many people say the blower on low is “near silent,” but mine is quite loud. There isn’t a rattle or any other sound to indicate the fan is broken, it just sounds like a really loud fan. On my blower, turning the dial clockwise goes from Off, to High just after the click, and then is supposed to transition all the way to low on the other end of the dial. I’ve noticed that it transitions from High to Medium quickly (maybe a sixth of the way around the dial), but then the fan speed never changes after that, no matter how far I turn the dial. Is this normal behavior? Is there a fix, or should I return the fan for a replacement? Thanks!
