Answer to continue safely
Is it safe to keep using?
No. A shorted sensor causes the control board to misread oven temperature. The oven could overheat without proper feedback. Do not use the oven function. Cooktop burners remain safe to operate.
Can I reset the code?
Yes. A power cycle can temporarily clear the error. If moisture was the cause, drying may permanently resolve it. Otherwise, the code will return.
When to stop immediately?
Stop if you notice: Stop using the oven if F2 returns after a power cycle and drying period., If you detect any burning smell from the sensor area, disconnect power immediately..
Symptoms You May Notice
Oven turns off immediately after starting
The oven begins its preheat cycle but shuts down within seconds, displaying the F2 code.
Display shows extremely high temperature
The temperature display may briefly show an unrealistically high reading before the error appears.
F2 error code on control panel
The display shows F2 and the oven becomes unresponsive until the code is cleared.
Oven preheats but overshoots dramatically
Before the error triggers, the oven may appear to read temperatures far above the set point.
Possible Causes
Shorted temperature sensor
The NTC thermistor inside the oven has a short circuit, sending near-zero resistance to the control board.
Requires ProfessionalPinched or damaged sensor wiring
The sensor wires are touching each other or grounding against the metal oven frame due to insulation damage.
Requires ProfessionalMoisture contamination
Steam or liquid has entered the sensor or connector area, creating a low-resistance path between conductors.
DIY PossibleSafe Checks You Can Do
-
1
Power cycle the range
Disconnect power at the breaker for 2 minutes. If moisture is suspected, wait 30 minutes to allow drying before restoring power.
Moisture from steam cleaning or heavy cooking can trigger a temporary short.
-
2
Inspect the sensor visually
Look at the oven temperature probe at the rear wall of the oven cavity. Check for bent or damaged housing.
If you recently ran a self-clean cycle, the extreme heat may have damaged the sensor.
-
3
Check for water near sensor
Look for signs of moisture, condensation, or liquid near the sensor area and wiring connector.
Allow the oven to air-dry with the door open for several hours if moisture is present.
When to Call a Professional
Contact a qualified technician if:
- A multimeter test showing near-zero ohms at the sensor confirms a short circuit requiring replacement.
- Wiring damage inside the oven cavity requires professional routing and heat-rated replacement wire.
- Repeated F2 after sensor replacement indicates a control board issue.
