How to Fix / Troubleshooting

Safety: Do not open the control board's sealed power supply section. Risk of electric shock.

Steps:

Check outlet: Verify the outlet supplies correct voltage with a multimeter and that the plug fits firmly.
Avoid extension cords: Plug the refrigerator directly into a dedicated outlet.
Reset: Unplug for 10 minutes, then reconnect.

If F30 persists and household power is stable, the internal power supply is likely defective and the control board must be replaced by a professional.
