Harman Pellet Stove Problem
A hi-pitch noise when the auger is running, can be cured by oiling the auger motor, both front & rear. Tough to get at but not impossible. Also check on alignment of the drive chain as older models had rubber grommets holding the motor to the bracket, half of mine were missing. A new bracket is available, but don't wait for your dealer or Harman to tell you so.
I have found that for me anyway, Harman service and warrenty are non existant. I have fired my dealer and will find a better service outlet.
Allthough I am more than pleased with my Accentra purchased in October of 2004. I would, if I could do it over, go with a Vermont Wood Stove. There is a basket for wood stoves that utilizes a pellet brick, that would give the same results as a wood stove with no cutting, splitting of cord wood, stacking or drying and result in lower ash and handeling that is the benifit of the pellet stove.
