There is a heating / warming element in the back of the oven on the right-hand side that seems to stay on after operation - keeping the oven around 200f. I think this is a new occurence and may have only come about after running the self cleaning mode. The controls, including the display appear to be off. 
Does anyone know how to shut this off?
