Kitchenaide Gas Range Superba comes on by itself

The units oven is coming on by itself, it does not ignite but acts like someone is pressing the convection bake key, or sometimes dehydrate key. No error codes are displaying. The oven does still work. Not sure if their is a something in the keypad that should/could be cleaned, or if a part would need to be replaced. I turn the power off when not in use in case it decides to start when we are out.
