Frigidaire Range Error Code F031

F031 indicates that the control board has detected a shorted oven temperature probe (RTD) circuit. The RTD is the sensor that measures oven temperature, and a short in its circuit means the resistance reading is abnormally low. The range disables oven operation when this fault is active to prevent unsafe temperature conditions. The fault can originate at the probe itself, the connecting wiring, or the control board.

You should not attempt to use the oven portion of the range while F031 is active, as the control board has detected a fault in the temperature sensing circuit. Without accurate temperature sensing, the oven cannot regulate heat properly, which creates a potential safety hazard. Surface burners on a gas or electric range may still function, but the oven should remain off until the fault is resolved.

Disconnecting the range from power for several minutes may temporarily clear the F031 fault, but if the underlying short condition in the probe circuit still exists, the error will return when the range is powered back on and the control board re-checks the RTD circuit. A reset alone is not a fix. The probe, wiring, and connectors must be inspected and the root cause corrected for the fault to stay clear.

A knowledgeable DIYer can perform basic diagnostics, including inspecting the probe wiring for visible damage and measuring RTD resistance with a multimeter. If the probe itself has failed, replacing it is a relatively straightforward repair involving disconnecting the old probe and installing a new one. If the control board requires replacement, the complexity increases and a professional technician may be a better choice.

If only the RTD probe requires replacement, parts typically cost in the range of $20 to $60, with professional labor adding $75 to $150 depending on your area. If the control board is the faulty component, board prices generally range from $100 to $300 or more, plus labor. Getting a diagnostic call from a technician first can help identify the actual failed component before committing to parts.
