I have had great luck for with my Harman Accenture for the past 8 years replacing an auger and convectiion blower. The stove runs but blows low heat, After following advice on the forum I cleaned the ESP and the stove worked fine for a week but now the same low blowing returns. When I asked for an appointment to service the Harman, the dealer states that as I filed a complaint about their service in the past they will not service the stove. If the dealer refuses service on a Harman product and Harman policy is that I must do business with the Harman dealer who sold me the stove where do I find a Harman service that will service the stove?
