Does the WSM run hot when brand new?
According to Weber, the unit may run up to 50°F hotter when new. The shiny interior surfaces reflect heat back into the cooker, resulting in higher than normal cooking temperatures. After 2-3 uses, a layer of smoke and grease builds up on the interior. As a result, it becomes less reflective and absorbs more heat, which radiates out of the cooker and results in lower cooking temperatures. However, it should be noted that not everyone notices this 50°F difference.
