Kitchen Aid Convection Range,KERC607EWH0. I press "Bake" on the electronic oven control it should set to 350 degrees. As of last night when I press "Bake" it automatically sets to 180 degrees. and will not allow me set higher than 260 degrees with out getting an "Err". I also tried other oven setting pads and it sets to odd degrees such as when pressing convection bake its sets to 75 degrees Thank You!
