Kenmore Range Error Code 51

Error code 51 on a Kenmore induction range indicates a break or open circuit in the temperature sensor for the left front induction cooking zone. The control board cannot receive a valid signal from the sensor that monitors heat at that burner, so the zone is disabled as a safety precaution. The fault may be caused by a loose connector, a damaged wire, or a failed sensor.

The left front induction zone will be disabled while error code 51 is active, so you cannot cook on that burner. The other cooking zones on the range may still function normally. It is not recommended to attempt to bypass or ignore the fault, as the temperature sensor is a safety-critical component that prevents the inductor coil from operating without proper thermal monitoring.

Performing a reset by unplugging the range or cutting power at the breaker for a few minutes may temporarily clear the displayed code. However, if the underlying cause, such as a disconnected sensor or a failed thermistor, has not been corrected, the fault will return as soon as the range attempts to use the left front induction zone again. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.

The first step, checking that the inductor temperature sensor is firmly connected to the induction housing assembly connector, is something a careful DIYer can perform after unplugging the range. If a loose connector is the cause, reseating it may clear the fault without any parts or tools. However, if the sensor itself or the wiring harness has failed, those repairs involve disassembling the cooktop and working near induction components, which is better suited for a qualified technician.

If the fix is simply reseating a loose connector, the repair costs nothing beyond your time. Replacing an inductor temperature sensor typically runs in the range of $20 to $80 for the part alone, depending on availability. If a technician is needed for diagnosis and repair, expect total costs in the range of $100 to $300 depending on local labor rates and whether additional parts like a control board are required.
