How to Fix / Troubleshooting
Safety first: Turn off power before touching wiring.
- Check power source: Ensure the refrigerator is plugged directly into a properly grounded outlet (no extension cords). Test the outlet with another appliance or a voltage tester.
- Inspect power cord: Look for kinks, cuts, or burn marks on the Electrolux power cord. Replace if damaged.
- Reseat main board connectors: Remove the rear access cover, then unplug and reconnect the main control board connectors one at a time to clean contact surfaces.
- Monitor operation: After restoring power, monitor for 24–48 hours. If intermittent codes persist, the main control board’s power supply section is likely failing and should be replaced.
