Error code 51
Appliance Cooktop
Quick answer

The left front temperature sensor has failed when code 51 appears. The manual's check is a resistance reading, then element or board replacement.

Model compatibility

Kenmore reuses codes across series and model years, so 51 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Meaning of 51

Manual remedy

  • Technician: measure the element sensor with a volt/ohm meter, expecting roughly 1000 ohms when the cooktop is at room temperature.
  • Sensor defective: new element, which includes the sensor.
