Hi all, I purchased my pellet stove 3 1/2 years ago, II have never been able to get it running. It runs for an hour, then goes out. I think it overheats, then comes up with an error code. I called United Stove, they have a customer service, but no service reps. They thought it might be a circuit board, they sent a replacement, I had it put in, same problem. Im not sure if its a fan problem or what? Any ideas, before I get some good use out of it and use it as a boat anchor.
