this is the sensor it is #43 on the look up. The f-2 says the oven has gone over temp. If you have a meter you can test it and order a new one. It should read around 1050-1100 ohms at room temp. If you do not have a meter most parts stores will test it for you. Unplug the unit and find the sensor in the upper corner in the oven. Remove the two screws that secure it. If the sensor checks good you will have to replace the control. Click here for parts.
