How to Fix / Troubleshooting

Step 1 – Check door closure:

  • Ensure all doors are fully closed and not obstructed by food items or shelves.
  • Verify that gaskets are sealing properly.

Step 2 – Inspect door sensors:

  • Locate the door switch or magnetic sensor (often at the top of the cabinet or in the door frame).
  • Check that the magnet in the door is present and aligned with the sensor.

Step 3 – Test the door switch (advanced):

  • Unplug the refrigerator.
  • Remove the sensor cover and disconnect the switch.
  • Use a multimeter to test continuity when the switch is pressed or when a magnet is applied.
  • Replace the Door Switch or Door Reed Sensor if faulty.

Step 4 – Reassemble and test:

  • Reinstall the sensor, restore power, and verify that the dE error and alarm stop when doors are closed.

Note: If sensors are good but the error persists, the Main PCB may be misreading the inputs and should be checked by a technician.
