Frigidaire F1 Error Code with a beep//EOC or Temp sensor

I just go home from a trip and my wife says the oven has a problem

It show an F1 error code on power up. It also emits a repeating beep that is unsilencable, except to pull the plug or throw the breaker.

After reading the forum I suspect that it is an EOC but some threads have pointed to a Temp sensor. Any help on this issue would be greatly appreciated. I would rather not spend the big money on the EOC if I can get away with a Temp sensor.

Thanks
