Recently, the control panel on my double oven went completely blank, but randomly displayed the error code F2-E2 or vice-versa and beeped randomly. I had atechnician check it out and he said that it was a bad control panel. I replaced the control panel and when I turned on the power, the panel displayed power failure error code and the clock displayed . I was able to set the clock to the correct time and then a few minutes later the entire screen went blank and no error code or random beeping occurred. However, each of the various "buttons" when pushed made a beep. When I pushed and held the "enter" button, a fan turned on for a few seconds, but the screen was still blank. Is it possible that the control panel is not working and /or does the control board need replacing?
