The fault code of F2 and F3 is indicating an oven sensor failure or the oven sensor circuit has loose or corroded wire connections. The oven sensor is a component that senses the oven temperature.
The oven sensor will have to be tested for the proper resistance to determine if it's good or bad. There is always the possibility of the oven control board being the cause of the fault codes as well, but most likely it's a failed oven sensor. Part number WB21X5301.
I recommend calling a service technician to test the oven sensor and diagnose if it's the oven sensor or the oven control board.
If you want to repair the range yourself and have a volt/ohm meter, send another question and we will furnish you the test for the sensor.
