We had a thunderstorm blow by and my oven went on the blink.
It now displays F7 a couple of minutes after being powered on.
(I can set the time in the meantime)
"problem solving" in the manual says F7 is a result of the touch panel signalling a touch/push for an excessive amount of time.
I am guessing that either a panel signal output or the corresponding control board input got zapped.
Any good ideas?
