GE Range Error Code F031

F031 on a GE range means the electronic control board has detected a short circuit in the oven temperature probe (RTD) circuit. The probe is responsible for measuring oven temperature and sending that data to the control board as a resistance signal. When the resistance drops abnormally low due to a short, the control board triggers this fault and disables oven operation. The probe itself, its wiring harness, or the connector are the primary areas to inspect.

It is not recommended to use the oven while F031 is active. The error indicates the control board cannot accurately read oven temperature, which means the oven may not heat correctly or could behave unpredictably. The control board typically disables oven operation when this fault is present as a safety precaution. Surface burners on a gas or electric range may still function, but the oven should not be used until the fault is resolved.

Repair costs depend on which component has failed. A replacement oven temperature probe typically costs in the range of $20 to $60 for the part alone, making it one of the more affordable repairs if the wiring is intact. If the wiring harness needs repair or replacement, parts and labor costs can increase. Professional appliance repair service calls generally range from $100 to $250 or more depending on your location and the extent of the repair needed.

A knowledgeable DIYer can diagnose and fix F031 by inspecting the probe wiring for visible damage and testing the probe resistance with a multimeter at room temperature, which should read approximately 1080 to 1100 ohms. If the probe reads near zero ohms or shows a direct short, replacing the probe is a straightforward repair that involves unplugging the range, removing the probe from the oven cavity, and connecting the new sensor. If the wiring harness is the problem, repair complexity increases depending on where the short is located. Always disconnect power before inspecting any components.

A reset, performed by disconnecting power to the range for several minutes and restoring it, may temporarily clear the F031 code, but the fault will return if the underlying short in the probe circuit is not repaired. The error is triggered by a real electrical condition that the control board detects each time the oven is activated. A reset is useful for confirming whether the fault is intermittent, but it is not a repair solution.
