I have a magic shef and as I push bake button and try to increase temperature to 300 degree a F3 code starts flashing and Oven does not cook.
Any idea what is it?

Thanks

The F3 code means there is a fault in the sensor circuit.

Check the oven sensor it should read approximately 1100 ohms at room temperature.

If sensor is good replace the oven control.
