I didn't see this post. I'm thinking this controller is malfunctioning as RemE thinks also.Thanks for the info and the suggestions. I will double check the wiring. Yes, it is correct, both the auger and fan are running continuous and not being controlled. I put a new controller on it (after market bac365) and having the same issue, running continuous. Will get really hot on smoke, then hit an error message and shut off (see attached files). The first one is the error message and looks like it says "Her." The second one shows it at 462 on smoke.
