The F2 error on your Frigidaire means the oven has detected that its internal temperature is too high, or the electronic control board sees a fault in the temperature sensing circuit. In most cases this is a safety response, and you can often clear it yourself before deciding if a repair call is needed.

Error code F2
Meaning Oven temperature exceeded the safe limit or the control board detected a shorted/open temperature sensor circuit
Severity Medium — the oven will usually shut off heating elements until the fault clears
Time to fix 10–45 minutes
Tools needed Multimeter (for sensor testing), screwdriver

What the F2 error means

Frigidaire ovens use a temperature sensor (a probe mounted inside the oven cavity) to report the current temperature to the electronic control board. If the board reads a temperature above the built-in safety limit, or the sensor’s resistance readings fall outside the expected range, it triggers the F2 fault code and locks out the bake and broil elements as a protective measure.

This can happen because the oven genuinely got too hot, or because the sensor itself, its wiring, or the control board is misreading the signal even though the oven temperature is normal.

Common causes

  • Faulty or degraded oven temperature sensor giving inaccurate readings
  • Loose, corroded, or damaged wiring connection between the sensor and control board
  • Oven door left ajar during a high-heat self-clean cycle, causing heat buildup
  • Stuck or shorted relay on the electronic control board
  • Sensor touching the oven wall, giving a false high-temperature reading
  • Power surge or electrical interference affecting the control board

How to fix the F2 error

  1. Power cycle the oven: Turn off the oven at the breaker for 5 minutes, then restore power. This clears many temporary control board glitches.
  2. Let the oven cool fully: If the code appeared during or after a self-clean cycle, let the oven cool for at least an hour before running it again.
  3. Check the sensor position: Open the oven and make sure the temperature sensor probe is not touching the oven’s interior wall, as this causes false high readings.
  4. Inspect the sensor and wiring: With the oven unplugged, check the wiring harness at the back of the sensor for looseness, corrosion, or damage, and reseat the connector firmly.
  5. Test the sensor resistance: Use a multimeter to check the sensor’s resistance against the manufacturer’s spec (typically around 1,100 ohms at room temperature). Replace the sensor if readings are far off or unstable.
  6. Call a technician if it persists: If the code returns after these steps, the control board itself may be faulty and should be tested or replaced by a qualified appliance repair technician.

FAQ

Can I keep using my oven if it shows an F2 code?
No. The oven will typically shut off the heating elements automatically. It’s best to power cycle it and address the underlying cause before cooking again.

Is the F2 error dangerous?
It’s a built-in safety response rather than a hazard itself, but repeated F2 codes can mean a sensor or control fault that should be checked to avoid uneven cooking or heating element damage.

Do I need to replace the whole control board for an F2 error?
Not always. Most F2 errors are caused by the temperature sensor or its wiring, which are cheaper and easier to replace. The control board is usually only replaced if the sensor tests fine and the code persists.
