a housing defining a cooking area, the cooking area to be heated;

a mounting bracket coupled to a side wall of the housing, the mounting bracket having a cavity defined by a first side surface, a second side surface spaced apart from and located opposite the first side surface, a front surface extending between the first side surface and the second side surface, and a rear surface spaced apart from and located opposite the front surface and extending between the first side surface and the second side surface, the front surface defining a slot to allow access to the cavity, the mounting bracket defining a thermal barrier provided by an air gap between the front surface and the rear surface, the rear surface having an opening proximate the side wall of the housing when the mounting bracket is coupled to the housing, the mounting bracket being formed of an electrically conductive material; and

a controller removably couplable to the housing via the mounting bracket, the controller having an engagement member structured to be at least partially received by the slot of the mounting bracket, the thermal barrier positioned between the controller and the housing when the controller is coupled to the mounting bracket, the thermal barrier to protect internal electronics of the controller from heat generated within the cooking area of the housing.
