Samsung wine cooler displays E8 and the interior light or control panel may behave abnormally.

Safety first: Unplug the unit before removing any trim or control panels.

• 1. Check door operation: Open and close the door while observing the interior light and display. If the light flickers or does not respond, the door switch may be faulty.
• 2. Locate door switch: On many Samsung wine coolers, the door switch is located in the cabinet frame or integrated into the control panel area. Some models use a magnetic reed switch with a magnet in the door.
• 3. Inspect magnet alignment: If your model uses a magnetic sensor, ensure the magnet in the door aligns properly with the sensor when closed. Adjust door hinges or magnet position if needed.
• 4. Test switch continuity: With power disconnected, remove the switch and test it with a multimeter while pressing and releasing the actuator (or moving a magnet near a reed switch). Replace if it does not open and close reliably.
• 5. Check wiring: Inspect the harness from the switch to the main PCB for breaks or loose connectors.
• 6. Main PCB check: If the switch and wiring are good but E8 persists, the main control board’s door input circuit may be defective.

Note: A faulty door switch can also cause temperature issues because the fan or compressor may be disabled when the door is sensed as open.
