Before I start opening the stove or call the dearler I want to see if anyone else has this kind of problem? My Accentra installed this past march is now making a high pitch squeal when the feeder is on. The problem is that it is doesnt do it all the time. It did this all day, and just now all I did was to move the pellets inside the hopper (it is half full) and the noise stopped??? I can't make any sense of this... Anyone experienced anythign similar?
