It sounds like moisture/condensation from the 'thousands' of steamy cooked items have finally got to the control panel/control board. You could try to locate a control board and replace the wonky one. I'd only try it if it's a custom over-the-stove install that would be a hassle to deal with. If it's a countertop model, just replace it; it is 7 years old. Even with range hood style, get a replacement unit (measurements!) at an appliance store and get one with installation of the new and remove/dispose of the old. Costco may provide those services (I do not know).
