F4

The F4 error code generally means a bad temperature sensor or a short in leads to the sensor. Under room temperature conditions the resistance should be approximately 1100 ohms. If you are not comfortable around electrical apparatus and/or don't have an ohmmeter, you will need to contact an appliance repair technician. GE typically places a trouble shooting guide in the top of their ovens behind the touchpanel. You will have to remove three screws in the bottom of the touchpanel to open the panel. Be sure and turn off the power before opening the touchpanel!!!
