Answer to continue safely
Is it safe to keep using?
No. A shorted sensor causes temperature misreading. The oven could overheat. Do not use until repaired.
Can I reset the code?
Yes. Power cycle can clear F2 temporarily. If moisture was the cause, drying may resolve it permanently.
When to stop immediately?
Stop if you notice: Stop if F2 returns after drying and power cycling., If you detect burning smell from the sensor area, disconnect power..
Symptoms You May Notice
Oven turns off immediately
The oven begins preheating but shuts down within seconds, displaying the F2 code.
Display shows extreme temperature
The temperature display briefly shows an unrealistically high reading before the error appears.
F2 code with oven locked out
The display shows F2 and the oven becomes unresponsive until the code is cleared.
Oven overshoots set temperature
Before the error triggers, the oven may read temperatures far above the set point.
Possible Causes
Shorted temperature sensor
The NTC thermistor has an internal short circuit, sending near-zero resistance to the board.
Requires ProfessionalPinched sensor wiring
Sensor wires are touching each other or grounding against the oven frame.
Requires ProfessionalMoisture contamination
Steam or liquid in the sensor or connector area creates a low-resistance path.
DIY PossibleSafe Checks You Can Do
-
1
Power cycle the oven
Disconnect power for 2 minutes. If moisture is suspected, wait 30 minutes for drying.
Moisture from steam cooking can trigger a temporary short.
-
2
Inspect sensor probe
Look at the probe at the rear wall of the cavity for physical damage.
Self-clean cycles can damage sensors with extreme heat.
-
3
Check for moisture
Look for condensation or liquid near the sensor and wiring area.
Leave the oven door open for several hours to air-dry.
When to Call a Professional
Contact a qualified technician if:
- Multimeter test showing near-zero ohms confirms a short requiring sensor replacement.
- Wiring damage inside the oven cavity requires professional repair with heat-rated wire.
- Repeated F2 after sensor replacement indicates a control board issue.
