Electrolux Range Error Code 51

Error code 51 indicates a break or open circuit in the temperature sensor circuit for the left front induction burner. The control board monitors a thermistor in the inductor assembly through two blue wires, and when it detects no valid signal, it shuts down that burner zone. This is a protective shutdown to prevent uncontrolled heating. The fault points to either a loose connector, damaged wiring, or a failed thermistor inside the inductor unit.

The left front induction zone will be disabled while error code 51 is active, so it cannot be used for cooking. The other burner zones may still function normally depending on the control board behavior. It is safe to use the unaffected zones, but the faulty burner should not be relied upon until the fault is diagnosed and repaired. Do not attempt to defeat or bypass the error to force the burner to operate.

If the issue is simply a loose connector, there is no parts cost and only your time is involved. If the inductor assembly needs replacement, parts costs can range from roughly 80 to 250 dollars or more depending on the specific model and parts availability. Adding professional labor, total repair costs typically fall in the range of 150 to 400 dollars. Getting the connector and wiring checked first is worthwhile since it may resolve the fault without any parts expense.

A knowledgeable DIYer can start by checking whether the blue wire sensor connector at the induction housing assembly is fully seated, which requires accessing the cooktop components. If the connector is secure, testing resistance across the blue sensor wires with a multimeter is the next step, looking for a reading of approximately 1000 ohms at room temperature. If the thermistor reads open or far out of spec, the inductor assembly will need to be replaced, which is a more involved repair. Always disconnect power to the range before inspecting any internal wiring.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the fault code, but if the underlying problem persists, the error will return as soon as the control board runs its diagnostics again. A reset alone is not a fix. The sensor connector, wiring, and thermistor resistance must be physically inspected and corrected to resolve the fault permanently.
