Possible Causes
Failed power supply section on main PCB, Loose mains connection at terminal block, Faulty line filter module, Household voltage issues
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before opening any electrical compartments. Mains voltage is dangerous.
Steps:
- Check wall outlet: Plug another appliance into the same outlet to verify that it supplies correct voltage and is not controlled by a wall switch.
- Inspect power cord: Check the refrigerator power cord for cuts, burns, or kinks. Replace if damaged.
- Access main control PCB: Remove the rear or top cover to reach the main control PCB and mains terminal block.
- Check connections: Ensure the mains wires are firmly secured in the terminal block and that the ground connection is intact.
- Visual inspection of PCB: Look for burnt components, bulging capacitors, or cracked solder joints in the power supply section.
- Replace main control PCB or line filter: If the board shows damage or if there is no low-voltage output to other components, replace the Etna main control PCB and/or line filter module as required.
