Our oven overheated and after it cooled down still displays f10 error it is a free standing Frigidaire model ffef3048lsm. Serial vt33155018 60 ha. How do we fix this

If you have an ohm meter and know how to use it, disconnect the temperature sensor (the probe you see protruding out of the back wall of the oven) and check the resistance it should be roughly 1100ohms at room temperature, if not its bad and needs to be replaced. If the sensor is good replace the main control board. If you don't have a meter the most common problem that causes the F10 error is the temp sensor just replace it. If that don't fix it then order and replace the control board. The parts for your model are linked below.
