Electrolux Oven F31 Error: Shorted temperature probe — probe resistance abnormally low.
Electrolux oven f31 error — understanding this error code helps you decide on the right course of action for your Electrolux appliance. What Does Electrolux Wall Oven Error Code F31 Mean? Error code F31 on your Electrolux wall oven (model ECWD3012A) means the electronic oven control has detected a short circuit in the temperature probe. […]

Answer to continue safely
Is it safe to keep using?
No. A shorted probe sends false temperature data to the control board, which could lead to no heating or erratic temperature regulation. Do not use the oven until F31 is resolved.
Can I reset the code?
Yes. A power cycle clears the F31 alarm, but the error will return when the control board detects the short again during the next heating attempt.
When to stop immediately?
Stop if you notice: Stop if you cannot access the probe connector behind the wall oven safely without professional help to handle the heavy unit., Do not bypass or jumper the probe circuit to force the oven to heat — this removes temperature safety protection..
Symptoms You May Notice
F31 displayed with alarm
The wall oven shows F31 on the control panel and beeps. All oven heating functions are locked out until the shorted probe condition is corrected.
Oven will not heat in any mode
Bake, broil, convection, and self-clean are all disabled because the control board cannot trust the temperature readings from a shorted probe.
Intermittent error during heating
F31 may initially appear only when the oven is heating, as thermal expansion worsens an intermittent short in the probe or wiring that is not present at room temperature.
Temperature display reads abnormally high
Before F31 locks out the oven, the temperature display may briefly show an unrealistically high temperature reading because the shorted probe simulates a very high temperature condition.
Possible Causes
Internally shorted probe thermistor
The NTC thermistor element inside the probe has developed an internal short from heat degradation of its insulating substrate, producing consistently low resistance readings.
DIY PossibleProbe wires touching due to insulation damage
The two probe conductors have lost insulation where they pass through the hottest section of the oven cavity wall, allowing bare wires to make direct contact.
DIY PossibleMoisture bridge at probe connector
Condensation from cooking steam has accumulated on the probe connector behind the wall oven, creating a conductive moisture bridge between the two pins.
DIY PossibleSafe Checks You Can Do
-
1
Measure probe resistance
Turn off the breaker, disconnect the probe plug if accessible, and measure resistance across the two leads. Normal is approximately 1,080 ohms at room temperature. Near zero or below 500 ohms confirms the short.
If you can only access the probe from inside the oven, a technician may need to help with the connector at the rear.
Tools required -
2
Dry the probe connector
If accessible, disconnect the probe plug and inspect for moisture, condensation, or corrosion. Wipe both the plug and socket with a dry cloth and allow them to air dry before reconnecting.
If corrosion is present, clean the pins gently with electrical contact cleaner before drying.

3
Inspect probe wires in oven cavity
Open the oven door and check the visible portion of the probe wires where they enter the cavity wall. Look for spots where insulation has melted, blackened, or cracked.
Do not pull or tug on the wires — just visually inspect for damage that might allow the two conductors to touch.
When to Call a Professional
Contact a qualified technician if:
- A replacement probe still triggers F31, indicating the wiring or control board sensor input has failed.
- Recurring moisture or corrosion at the probe connector suggests a ventilation problem behind the wall oven that a technician should address.
- The probe wiring has insulation damage inside the oven housing that requires disassembly to access and repair.
