Electrolux Range Error Code F031

F031 indicates that the oven relay board has detected a short circuit condition in the oven temperature probe (RTD). The board monitors the probe's resistance signal through pins 3 and 4 of connector J6, and triggers this fault when the resistance drops to an abnormally low level. This fault prevents the oven from operating normally until the probe or wiring issue is resolved.

It is not advisable to use the oven while F031 is active. A shorted RTD probe means the relay board cannot accurately read oven temperature, which could result in the oven overheating or failing to regulate heat correctly. The range stovetop burners may still function, but the oven should remain off until the fault is diagnosed and repaired.

If only the RTD probe needs replacement, parts typically range from $20 to $60 depending on the model, and a technician's labor for this repair usually adds $75 to $150. If the wiring harness or oven relay board is also damaged, total repair costs can range from $150 to $350 or more. Getting a professional diagnosis first can help determine whether repair or appliance replacement is the more cost-effective option.

A knowledgeable DIYer can perform the initial diagnostic steps, which involve unplugging the range, disconnecting the RTD connector at J6 pins 3 and 4, and checking resistance between each wire and chassis ground with a multimeter. If the harness checks out and the probe itself is shorted, replacing the RTD probe is a straightforward repair on most Electrolux ranges. However, if the fault involves the relay board or complex wiring damage, a qualified technician is recommended.

Unplugging the range briefly may temporarily clear the fault display, but the F031 code will return as soon as the oven relay board detects the shorted probe again on the next power cycle or heating attempt. A reset does not address the underlying hardware problem. The RTD probe or wiring harness must be inspected and repaired or replaced for the fault to clear permanently.
