So I bought a $3000 napoleon furnace this summer. Installed this fall, the thing works great WHEN the primary air control doesn't stick! About every 3 or 4 nights I awake to a cold house and a stove full of wood. I have taken it off several times to check it out and I think it is binding. I can tap it or work it up and down and it startes opening. Then a few days later it sticks again. So I email Napoleon and their reply is they haven't had any motor failures to date. They did give me a few things to check, which I did. I replied back that they have had their first motor sticking apparently. So now, they ignore me! Won't get back with me, now I'm stuck operating this $3000 furnace manually! I guess I'm gonna have to buy a new motor assembly IF I can ever get them to get back with me. I am starting to feel very bitter towards them, do you think its justified?
