Electrolux Range Error Code E51

The E51 error code on an Electrolux range indicates a break or open circuit condition in the temperature sensor associated with the left front surface unit. This sensor is part of the induction or radiant cooking zone's temperature monitoring system, which continuously feeds data to the generator board to regulate heat output and prevent overheating. When the control detects that the sensor circuit is open or reading outside of its expected resistance range, it triggers the E51 fault and typically disables that burner zone to protect the unit.

The generator board is the core component managing the left front cooking zone, and it communicates directly with the surface unit temperature sensor through a dedicated connector. A break in this circuit can stem from a physically damaged sensor, a disconnected harness, or a failed sensor element that no longer provides a valid resistance signal. Because the board relies on continuous sensor feedback to operate safely, even an intermittent loss of signal will cause this fault to register.

The first diagnostic step is to inspect the sensor's connection at the generator board connector. A loose, corroded, or unseated connector is the most common and easiest-to-resolve cause of this code. If the connection is confirmed secure and the fault persists, the sensor itself or the wiring harness between the sensor and the board should be tested for continuity and physical damage before condemning the generator board.
