I have a PB 105 and ever since I got it if i run out of pellets I get no error code the board has been replaced twice but still I get the same problem. Any ideas?? Other wise It has been running fine. I have also replaced the burn pot a few times and a few ignitors. I now have a SS burn pot from Harman, I installed it in the fall and it is starting to bump up but no cracks yet.
