F12Serious
Frigidaire Oven/Range F12 Error Code
The oven temperature sensor circuit is open, so the oven cannot detect temperature.
Common causes
- Broken sensor wire
- Disconnected sensor
- Faulty sensor
How to fix it
- Unplug the range.
- Check that the sensor connector is firmly attached.
- Measure resistance; an open circuit will show infinite resistance.
- Replace the sensor if it is defective.
⚠ When to call a pro: If replacing the sensor does not fix the issue, check the control board connector.
