Answer to continue safely
Is it safe to keep using?
No. A faulty temperature sensor in a gas oven means the gas valve cycling cannot be properly regulated. This can lead to overheating or inadequate heat. Do not use the oven until the sensor is replaced.
Can I reset the code?
Yes. A power cycle may clear the error temporarily, but the sensor issue will cause F2 to recur during cooking.
When to stop immediately?
Stop if you notice: If the oven temperature feels significantly different from the display reading., If you smell gas during normal oven operation, the cycling may be impaired..
Symptoms You May Notice
Oven temperature inaccurate or fluctuating
Food burns on one cycle and comes out undercooked on the next, even at the same temperature setting.
F2 displayed during preheat cycle
The error appears during the preheating phase, often preventing the oven from reaching the set temperature.
Oven shuts down mid-cooking
The oven turns off unexpectedly during a cooking cycle as the sensor provides erratic readings to the control board.
Temperature display jumps between values
The digital temperature reading fluctuates rapidly instead of climbing steadily during preheat.
Possible Causes
Defective NTC temperature sensor
The sensor probe has developed a short circuit or drift from prolonged exposure to high oven temperatures.
Requires ProfessionalCorroded sensor wiring connections
The wire connectors at the sensor or control board have corroded, creating intermittent contact.
Requires ProfessionalMoisture in sensor area
Steam from cooking or cleaning has entered the sensor housing or connector, affecting readings.
DIY PossibleSafe Checks You Can Do
-
1
Power cycle the range
Disconnect power for 2-3 minutes. If moisture is suspected, leave the oven door open for several hours before retesting.
Moisture-related sensor issues often resolve with thorough drying.
-
2
Inspect the sensor probe
Look at the temperature sensor at the top-rear of the oven cavity for visible damage, bending, or detachment.
The probe should be firmly mounted and the wire should be intact.
-
3
Test with oven thermometer
If the oven runs despite F2, place a standalone thermometer inside to verify actual temperature vs. display.
A difference of more than 25°F confirms the sensor is inaccurate.
Tools required
When to Call a Professional
Contact a qualified technician if:
- A multimeter resistance test at the sensor confirms whether it is within specification.
- Sensor replacement is a standard repair completed in about one hour.
- If the sensor tests correctly, the control board input circuit may need diagnosis.
