How to Fix / Troubleshooting

Safety (critical): Immediately unplug the wine cooler if you smell burning or see smoke. Do not continue to operate the unit.

Steps:

  • 1. Visual inspection: After the unit has cooled, remove the rear panel and inspect wiring, compressor terminals, and the main PCB for burn marks or melted insulation.
  • 2. Check fans and motors: Spin fans by hand; if seized or very stiff, replace the evaporator fan motor or condenser fan motor as applicable.
  • 3. Inspect PCB: Look for burnt relays or components. Replace the La Sommeliere main control board if any damage is found.
  • 4. Repair wiring: Replace any burnt or melted wires using the correct gauge and high-temperature insulation.

Recommendation: Due to fire risk, have a qualified technician inspect and repair any burning-smell fault before using the cooler again.
