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

  1. Unplug the range.
  2. Check that the sensor connector is firmly attached.
  3. Measure resistance; an open circuit will show infinite resistance.
  4. 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.
