I used the oven last night to cook dinner. When the timer shut off, I took my food out and pressed the off button on the control panel and the ellement in the oven did not shut off. It started beeping and throwing the F1 code. We unplugged it for about and hour and then plugged it back in. The oven element started to heat up again, so we unplugged it again. Could the problem be my clock circuit board or the element itself.
