Electrolux Range F31 Error: Confirmed shorted oven temperature sensor — secondary verification.
Electrolux range f31 error — understanding this error code helps you decide on the right course of action for your Electrolux appliance. What Does Electrolux Range Error Code F31 Mean? Error code F31 on your Electrolux range (model ECFD3068A) is a confirmed short-circuit detection for the oven temperature sensor. The electronic oven control performs multiple […]

Answer to continue safely
Is it safe to keep using?
No. The oven has no reliable temperature monitoring with a confirmed shorted sensor. Using the oven risks uncontrolled temperatures and is a safety hazard.
Can I reset the code?
No. F31 is a confirmed fault and will not clear with a simple reset. The underlying short circuit must be physically repaired by replacing the sensor or fixing the wiring.
When to stop immediately?
Stop if you notice: Stop if you see any charring or burn marks on the sensor wiring, as this indicates a potential fire hazard that needs professional repair., Do not attempt to repair the sensor itself — it must be replaced as a complete unit..
Symptoms You May Notice
F31 error displayed persistently
The control panel shows F31 and it does not clear after pressing Cancel, indicating the short circuit has been confirmed by the control logic.
Oven completely disabled
All oven functions — bake, broil, convection, and self-clean — are locked out because the control board cannot trust the temperature readings.
F11 may appear first
You may initially see F11, which then changes to F31 after the control board retests and confirms the short circuit condition on the sensor leads.
Cooktop remains functional
The stovetop burners continue to work normally because they operate independently of the oven temperature sensor circuit.
Possible Causes
Permanently shorted NTC sensor
The thermistor element has suffered a permanent internal short from heat degradation, producing consistent low-resistance readings that the control board confirms on retesting.
DIY PossibleMelted wiring insulation
The sensor wires have lost insulation near the oven cavity due to extreme heat exposure, allowing bare conductors to maintain constant contact with each other.
DIY PossibleControl board sensor input fault
The sensor input circuit on the electronic oven control board has a component failure that reads any connected sensor as shorted, regardless of actual resistance.
Requires ProfessionalSafe Checks You Can Do
-
1
Disconnect and measure sensor
Unplug the range, disconnect the temperature sensor, and measure resistance across its leads with a multimeter. Normal is approximately 1,080 ohms at room temperature.
If the sensor reads near zero ohms, it has a confirmed internal short and must be replaced.
Tools required -
2
Inspect wires near oven cavity
Check the sensor wires where they pass near or through the oven cavity wall. Look for melted, blackened, or missing insulation that allows the two conductors to touch.
Even a small section of missing insulation can cause a persistent short that triggers F31.
-
3
Test with sensor disconnected
With the sensor unplugged, restore power briefly and check if the error changes from F31 to F30 (open circuit). If it does, the control board input circuit is working correctly and the problem is in the sensor or wiring.
This swap test helps isolate whether the control board itself is at fault.
When to Call a Professional
Contact a qualified technician if:
- A new replacement sensor still triggers F31, indicating the fault is in the wiring harness or control board.
- There is visible burn damage to the wiring that runs inside the range cabinet and requires extensive disassembly.
- The error code does not change to F30 when the sensor is completely disconnected, pointing to a control board input fault.
