Was reading another post regarding cleaning the MES inside so I wanted to clean the temperature sensor. I thought it was this round deal on the left hand side back wall (the only clean thing in there). However I just read about a "shiny 3/16 bar" on the right hand side back wall 2/3 of the way up being the sensor. Confused again. There is (of course) nothing shiny anymore in there but I see no bar, just this round thing. There is a little tiny thing up in the left hand corner too. Got this smoker last June. Any input would be welcome on this. It still seems to work ok.
