I currently have a Harmon Accentra pellet insert. It makes a high pitched (like ringing in the ear sound) not constantly, but on and off and not in any paticular pattern. The dealer has been out twice, hasn't any clue as to what it is. I did not have this problem for the last two seasons. Sometimes its so loud I can hear it throughout the house. Any ideas?
