My oven stopped working in the middle of fixing Thanksgiving dinner. The stove top works fine but the oven just stopped. We checked the breaker and found no issues. We let the oven sit over night and were able to turn it on again and set the time. We then tried the oven and it came on and started heating up. We turned it off and a few minutes later the LED display was completely off again. When I open the oven door the light doesn't even come on when this happens. Any suggestions would be great. I am out of work right now and hate to pay repair costs, especially right here during the holidays.
