hello im new here and this is my problem. I bought a used pellet stove for my camp. installed it and worked great for 3 days. I had it pretty hot when the stove shut down and the h1 code came up. I did what the manual said to do. still the same. went back up to camp this weekend to punch in different codes that were mention in this site. still nothing. I took out the 2 250 sensors the 2 160 sensors and the 1 sensor that is in the exahaust. it has a gasket that wasn't any good. I tested them and they seem to work. (note) when I take a lead off of thhe 250, either the exhaust goes on or the auger. I hope its not the board. any suggestions?
