Gene, have read all you previous posts. I have the e6 f2 problem as well. unplugged the ribbon cable turned back on and got the e1 f2, them my display went blank. Yesterday it beeped a few times and went blank. If I cut the power for awhile and then restore it the oven will work for a short time and will sometimes give the e6 f2 and will sometimes just be entirely blank, put the panel will beep if i press buttons but the oven wont run. Not sure if I should go panel or board. any help would be appreciated.
