I have a GOSM 36" Smoker, tried to smoke some briskets over the weekend, but had problems getting the heat hot enough. I was able at first to easily get the temp up to about 250, but after I had the racks full smoke roaring and water in I couldn't get it above 209. It was 55 degrees outside with a 15 mph wind. So i brought it into our garage. Still could get the temp above 209 checking with digital temp. gauge. I noticed when I turned the value, from low to high, you would see a slight surge in the flame for about 1 second, then it would drop down as it was before and there was no difference in the flame that you could tell. Think I had this problem last time. But got the job done, put it away and forgot about it. Tore into it today, took the burner out and blew threw it to make sure it was not clogged. Took the value out and took the hoses off to check there, put burner, hoses and value back together on the floor and tried it again, still no difference in the flame. However when I was blowing air through the hose the value would control the air flow. Is it possible the regulator is bad?? I found the new Landmann site where they had parts listed for the GOSMs, but if I replaced the burner it would cost $60 or if I replaced the regulator, value assembly it would cost $60. So a trial and error would cost over the replacement cost of the smoker. (walmart $118.00). Any suggestions?? I am fix it type of person, but don't want to throw money away, if I can fix it with different parts that fine too!! Thanks LMN Rancher I tried a new propane tank too.
