Possible Causes

Unstable household voltage, Failing power supply section on main PCB, Loose power cord connection, Internal fuse or varistor damage on PCB

How to Fix / Troubleshooting

Safety first: Unplug the unit before opening any electrical compartments. High voltage is present on the power input side.

  • 1. Check outlet: Plug a different appliance or a voltage tester into the same outlet to confirm stable power. Avoid using extension cords or power strips.
  • 2. Inspect power cord: Examine the Samsung wine cooler’s power cord for cuts, kinks, or burn marks. Replace the cord if damaged.
  • 3. Access main PCB: Remove the rear control cover to expose the main board. Look for a blown fuse, burnt components, or bulging capacitors in the power supply section.
  • 4. Replace fuse (if serviceable): Some boards have a replaceable fuse. If blown, replace with the exact same rating. If it blows again immediately, there is a deeper fault that needs professional diagnosis.
  • 5. Replace main PCB: If the power supply section is visibly damaged or F2 persists despite good input power, replace the main control board.

Warning: Do not bypass fuses or safety components. If you are not trained in electronics, seek professional service.
