Jenn Air wall oven not heating

We have a Jenn Air electric oven that was given to us. Within the first week it starting flashing F1 and beeping, and would do so throughout the day. Then one day it stopped. Now a couple of months later it won't heat. You push BAKE and the temp will come on and the fan...but does not heat. The broil doesn't work either. I don't know the model #, but I have a picture instead. Hope this helps. Thanks.
