GE Wall Oven F3 Error Code
The Ge Wall Oven F3 Error Code is an oven temperature sensor fault. It means the temperature sensor is open (over 2850 ohms). The temperature sensor is the probe you see protruding out of the back wall inside the oven. Remove the screws that mount the temperature sensor bracket to the oven and pull it forward, disconnect the plug from the wiring harness and if you have an ohm meter you can test and see if it’s over 2850 ohms, if so the sensor is bad.
If the sensor is good the display module control board is bad. If you don’t have a meter or know how to use one just replace the temperature sensor because that is the most common failure that causes the F3 error. If replacing the sensor does not fix the problem the control board is bad.
