oven not working, gives me a code F3

My gas stove every so often beep with a f3 code or f1, went to try the oven and it just registed F3, need to know what to do?

A model number is necessary to look this up. F3 on many ranges means failed oven temp. sensor, but it can mean other things.

My model # 790.71513405 it is a kenmore.

Apparently Frigidaire made your range. F3 is a bad oven temperature sensor. F1 could a bad sensor or a bad computer.

The sensors fail sometimes and they are fairly cheap. part 316217008
