How to Fix / Troubleshooting
Safety: Immediately unplug the wine cooler if you smell burning or see smoke. Do not continue to operate the unit.
- Visual inspection: After the unit cools, remove the rear panel and inspect the compressor area, wiring, and control board for burn marks or melted plastic.
- Check start relay and wiring: Look closely at the compressor start device and nearby wires. Replace any components that show signs of overheating with OEM Aobosi parts.
- Inspect control board: Examine the PCB for burnt components or darkened areas. Replace the board if any damage is visible.
- Do not reuse damaged parts: Any charred connectors or wires must be replaced, not just taped.
- Professional service: If you are unsure of the source of the smell, have a qualified technician inspect the unit before using it again.
