Step-by-Step DIY Fix Guide
- SAFETY: Turn off power at the circuit breaker before inspecting the sensor or wiring.
- Locate the oven temperature sensor probe inside the oven cavity (rear upper wall, held by 1–2 screws).
- Inspect the connector where the sensor wire exits through the back wall — check for bent pins, moisture, or debris bridging the contacts. Clean and reseat the connector.
- Inspect the sensor wire from the probe to the connector for damaged insulation or bare wire contacting the oven chassis.
- To test the sensor: with power off and the sensor wires disconnected, measure resistance with a multimeter. A room-temperature probe should read approximately 1,080–1,100 ohms. A reading far below this (near zero) confirms a shorted sensor.
- Replace the sensor if it tests shorted — remove the two mounting screws and unplug the connector. Install the replacement and route the wire away from sharp edges.
- Restore power and test. If F31 returns, the wiring harness or control board needs professional diagnosis.
If the warning comes back after restart
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- F31 persists after replacing the sensor and confirming the harness wiring is intact
- The connector pins are visibly burnt — a burnt connector requires harness replacement before any further use
What This Error Means
Error F31 on your Electrolux oven means: The oven's control board is detecting a shorted condition in the oven temperature sensor circuit. The sensor is reading an abnormally low resistance, which the control board interprets as a temperature far outside the oven's operating range. F31 is the complement to F30: F30 is an open circuit, F31 is a shorted (low-resistance) circuit. The oven's self-diagnostic system has detected this condition and restricted operation.
The most frequent cause is oven temperature sensor probe shorted internally — resistance wire contacts itself due to physical damage or insulation breakdown. Work through the causes and fix steps below in order — many Electrolux oven errors are resolved with a power cycle or a simple part swap.
Many cases of F31 can be resolved by the homeowner using the steps below. If the DIY checks do not resolve the error, a technician is needed.
The oven temperature sensor is a straightforward part to test and replace on most Electrolux ranges. A multimeter set to ohms is all that is needed — a room-temperature probe should read approximately 1,080–1,100 ohms. If it reads open or near zero, the sensor is the cause and replacement will clear the code.
Most Likely Cause by Symptom
The Electrolux oven may stop, pause, or refuse to complete the cycle normally.
Likely cause: Oven temperature sensor probe shorted internally — resistance wire contacts itself due to physical damage or insulation breakdown
Check first: SAFETY: Turn off power at the circuit breaker before inspecting the sensor or wiring.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Connector pins on the sensor harness are touching each other (bent pins or moisture bridging the contacts)
Check first: Locate the oven temperature sensor probe inside the oven cavity (rear upper wall, held by 1–2 screws).
Common Causes
- Oven temperature sensor probe shorted internally — resistance wire contacts itself due to physical damage or insulation breakdown
- Connector pins on the sensor harness are touching each other (bent pins or moisture bridging the contacts)
- Damaged sensor wire with stripped insulation creating a short to the oven chassis or adjacent wire
- Control board sensor input circuit has failed in a way that reads the probe as shorted
What Not to Do
- Do not use the oven with F31 active — a shorted sensor causes the control board to misread temperature and may allow the oven to overheat
Model and Display Variation Notes
Model-family notes
- Electrolux oven display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Common parts
- Oven temperature sensor/RTD probe ($20–$50)
- Sensor wiring harness if insulation is damaged ($15–$35)
Manual and model check
Check your exact model and manual before ordering any Electrolux oven parts.
Service option

When Not to Keep Troubleshooting
F31 persists after replacing the sensor and confirming the harness wiring is intact
- The connector pins are visibly burnt — a burnt connector requires harness replacement before any further use
How to Prevent It Recurring
- Route the sensor wire carefully when reinstalling the oven after servicing — wire pinched against the rear wall or the chassis becomes a short circuit over time
