Possible Causes
Failed internal power supply module, Loose mains connection at terminal block, Blown internal fuse on main control PCB, Damaged surge components after power spike
How to Fix / Troubleshooting
Safety: Unplug the wine cooler and wait several minutes before opening any electrical compartments. Only proceed if you are comfortable working around mains voltage components.
- Check outlet: Verify the wall outlet supplies correct voltage and is not controlled by a switch or GFCI that has tripped.
- Inspect power cord: Look for cuts, kinks, or burn marks. Replace the cord if damaged.
- Access PCB: Remove the rear panel to access the main control PCB and power input area.
- Internal fuse: Locate any PCB-mounted fuse and check continuity with a multimeter. Replace only with the same type and rating if blown.
- Terminal block: Ensure live, neutral, and earth wires are firmly secured in the terminal block with no signs of overheating.
- Power module: If the low-voltage section of the PCB shows burn marks or bulging capacitors, the power supply is likely defective. Replace the main control PCB or power module as a complete unit.
- Surge protection: After repair, consider using a surge-protected outlet to protect the new electronics.
