Mine has just been repaired. We were able to turn off at wall and leave a while and on return if you are luckey the clock may start,then the oven. We did this a few times but took some patience. Anyway the fault is the Console Control Module and needed replacement.
Part 572942p for mine approx 18 years old. Cost with F& P call out fee = $386.00...Alex
