The wall control unit of my Mt. Vernon has been acting up intermittently. Sometimes, adjusting the temperature causes the screen to go blank and flash - light up and get dark. It's totally random and will sometimes correct itself after a 15-30 seconds back to a normal display. However, sometimes it will flash for longer periods and when that happens, I have to cycle the power to the stove to restore the screen.
Now it has been occuring more frequently in the last few days. Do I need to replace the wall control or perhaps the control board in the stove? Or is there something else I can check?
