I can tell now after 3 cooks I had a fire in my box, tonight I set temp at 200 and put my wood in a stainless steel sink strainer. I monitored the temp the whole time. 225 highest ,187 lowest after 3 cycles. This cook was the best I have had so far. I believe my wood chunks were falling on the heating element causing the fire. The previous smoke I did on chix legs, they were black, tonight, they ha the mahogony color I like. Do you all think I need the chip tray, or just put aluminum foil down over wood box? Thank you all for your input, I know I will eventually like this smoker once I get used to it.
