Electrolux Range Error Code F030

The F030 error code on an Electrolux range indicates an open circuit condition in the oven temperature sensor, also referred to as an RTD (Resistance Temperature Detector). The RTD is a probe-style sensor mounted inside the oven cavity that monitors cooking temperatures by changing its electrical resistance in proportion to heat. The oven control board reads this resistance to regulate the bake and broil elements accurately. An "open" condition means the control board is detecting infinite or out-of-range resistance on the sensor circuit, which prevents normal temperature regulation and shuts down oven operation as a safety measure.

The diagnostic process begins at pins 3 and 4 of connector J6 on the oven relay board. With the range unplugged and the sensor connector disconnected, resistance should be measured between each individual wire and chassis ground. This isolates whether the fault lies in the sensor itself, the wiring harness between the sensor and the relay board, or the connector terminals. A properly functioning RTD sensor typically reads around 1080 to 1100 ohms at room temperature. Readings that are significantly higher, erratic, or show open circuit (OL on a multimeter) confirm a failed sensor or broken wire.

Common root causes include physical damage to the sensor probe from contact with cookware, corrosion or carbon buildup at the connector terminals, a break in the sensor wiring harness, or outright failure of the RTD element itself due to age or thermal stress. Because the oven cannot safely regulate temperature without a valid sensor signal, the F030 code will lock out oven functions until the fault is corrected.
