I have a AMNPS for my masterbuilt and have successfully used it for years. Recently I upgraded my units controller to an Auber and since then (possibly coincidence) my pellets seem to not smoke much, if at all. I used to get about 4 hours per row on the AMNPS, which is typical, now I am lucky to be able to keep the pellets smoking. The pellets are the same I have always used, as I bought a 40lb sack and keep them in a bucket with lid. I dont put any water or liquid in my smoke box so thats not the issue. I also have been warming the pellets in the oven prior to lighting them, to warm them up and maybe dry them out (doubt they need it). Warming the pellets does seem to help but I am getting very limited smoke and a row is lasting significantly longer than it used to. I have tried moving the exhaust vent (typically wide open) to no avail. Do I need to drill extra holes in the old smoke tray to bring in more oxygen? Any other tips?
