    What to do if my Kenmore Microwave Oven shows a sensor open error?
    • J
      Juan Gates DDSAug 4, 2025
      If your Kenmore Microwave Oven displays a 'Sensor open error', the issue might stem from an unplugged sensor, faulty wiring, or a problem with the smart board. Begin by inspecting the sensor and its wiring. If these appear normal, replacing the sensor might resolve the error. However, if the error surfaces specifically when initiating a sensor function, replacing the smart board is recommended.
