I have had a 30" Smoke Hollow LP smoker (Model #30164G) for 2 years now. I have had very good luck with it and it has produced some very good food. In the past 3-4 months the smoker will not get above 275 with nothing in it. And when I say nothing, I mean no meat, racks, wood pan, drip pan, etc.! When I put the wood pan in there with chunk wood, it will not burn the wood. It just smolders and eventually the wood burns out and does not produce much smoke. The wood retains its size, just looks like a black lump of coal when it goes out (it used to not do this). It used to completely burn the small chunks. I have had to resort to using chips and even then some of those will not completely burn. I have tried several positions with the vents as well...top all the way open, bottom all the way open, partially closed on top and/or bottom, etc. When the smoker is fully loaded, i have to run it on high to keep it in between 200-225. While it does run MY ideal temp range for slow smoking, i would like it ot be able to run higher temps for chicken like it used to. It would also be nice if it would run at least 250 for some things. When I first got the smoker it could run all the way up to 375-400 on high when empty and easily maintain 275-300 when full of meat. I pulled the burner out and cleaned the heck out of it and cleaned the fuel line this last week and still did not help.
What do you all think could be the problem? Possibly a new burner needed? New fuel line? New smoker??? I appreciate any input you all may have. Thanks!
