Electrolux Oven Error Code F30

F30 means the Appliance Control Board is detecting an open circuit in the lower oven RTD temperature sensor probe circuit. The board cannot receive a valid resistance reading from the probe, which is required to monitor and regulate oven temperature. This is typically caused by a failed probe, broken wiring, or a faulty connector in the probe circuit.

You should not attempt to use the oven while F30 is active. Because the control board cannot read the lower oven temperature, it cannot properly regulate heat, which creates a risk of overheating or unpredictable oven behavior. Discontinue use until the probe circuit issue is identified and repaired.

Resetting the oven by disconnecting power for a few minutes may temporarily clear the F30 code, but it will return as soon as the control board checks the probe circuit again and finds the open condition. A reset does not fix the underlying wiring or sensor problem, so a proper diagnosis and repair of the probe circuit is necessary to resolve the error permanently.

A knowledgeable DIYer can often diagnose and fix F30 by inspecting the probe wiring and connectors for visible damage and testing the probe with a multimeter for continuity. If the wiring and connectors check out, replacing the lower oven RTD probe is a relatively straightforward repair that involves disconnecting the probe, removing a mounting screw or two, and installing a new probe. If the control board itself is at fault, that repair is more complex and may warrant professional service.

If only the RTD probe needs replacement, parts typically range from $20 to $60 depending on the specific model, plus any labor costs if a technician performs the repair. If the wiring harness requires replacement, costs will be higher. A full control board replacement, if ultimately needed, can range from $150 to $350 or more for parts alone.
