Today is my first smoke. It is about 37 degrees outside and my smoker is set to 240, yet maximum temp on the gauge is 219. However, I put a 8x10 ceramic tile on top of the smoke box to try to keep the temperatures even and 2 additional charbroil temp gauges on the top rack, one left front and one right front. The left front gauge reads 250 and right front gauge reads just under 300. (I think I need a bigger piece of tile to block out more heat). Is the built in gauge suppose to be that off? is there suppose to be that much of a temperature difference between tieh left and the right even with the tile in? Will post more pics once the chicken is done. Here is how it started off though....skinless boneless chicken breast from Costco, seasoned with Memphis seasoning and wrapped in bacon. I didn't realize how much bacon I needed, barely covered the chicken!
