What Does Error F31 Mean?
The Frigidaire oven error F31 indicates a malfunction in the temperature sensor circuit, often caused by a faulty RTD sensor or damaged wiring. This error leads to erratic temperature readings, failure to heat, and can cause the oven to shut off unexpectedly or not start at all. Inspecting the sensor and wiring can help diagnose the issue.
Common Symptoms:
- Oven displays F31 code when attempting to heat
- Oven fails to reach or regulate temperature
- Oven may shut off or refuse to start heating
- Inconsistent temperature behavior reported before error
Possible Causes
- Faulty oven temperature sensor (RTD) (high)
- Damaged or shorted wiring between temperature sensor and control board (medium)
- Less common control board input failure (medium)
How to Fix Error F31
DIY Fix Basic user troubleshooting steps
- Disconnect power to the oven (unplug or switch off circuit breaker) for 5–10 minutes to attempt reset
- Visually inspect the interior temperature sensor (located inside the oven cavity) for obvious damage
- Ensure the sensor’s wiring connection isn’t loose at the sensor end (do not open panels if uncomfortable)
Technician Only Technician‑level diagnosis and repair
- Verify power to the oven is disconnected
- Access oven interior and back panels to reach temperature sensor and wiring harness
- Measure the RTD sensor resistance with a multimeter at room temperature; replace sensor if resistance is outside spec or near short
- Inspect and repair/replace damaged wiring harness between sensor and control board
- If sensor and wiring test good but F31 persists, test the control board input circuit and replace the control board if necessary
Parts needed: RTD temperature sensor, Wiring harness, Electronic control board
- If you are uncomfortable working with internal electrical components
- If replacing the temperature sensor and wiring does not clear the error
- If diagnostic testing points to control board failure
