How to Fix / Troubleshooting

Safety (critical): Immediately unplug the wine cooler. Do not continue to operate a unit that smells like burning plastic or chemicals.

Steps:

  • Ventilate the area: Open windows and doors to clear any fumes.
  • Inspect rear compartment: After the unit cools, remove the rear panel and look for burnt components on the main control board, start relay, or wiring.
  • Do not bypass safety devices: Never bypass thermal fuses or overloads.
  • Replace damaged parts: Any burnt or melted components must be replaced with Bosch-approved parts. If damage is extensive, replacement of the entire appliance may be more economical.
  • Professional service: Because fire risk is involved, have a Bosch-authorized technician inspect and repair the unit.
