I have electric thermador built in convection oven. Had power outage Sun, Feb 4,2024. First time ever that I cannot get time on clock to key in as 1st step to reset for time, day, date. Tried turning on oven, NOTHING. My oven will not work no matter what I've tried to do to reset it. When power went out it was huge surge during big CA weather event. Help PLEASE,I NEED MY OVEN!!
