Strong chemical or burning smell coming from the rear of the unit.

Safety first: Immediately unplug the wine cooler if you smell burning or see smoke. Do not continue to operate it.

• Visual inspection: After the unit cools, remove the rear lower panel and inspect the main control board, compressor start relay, and wiring for burn marks or melted plastic.
• Replace damaged parts: Any burnt or melted components must be replaced with OEM or NEEDONE-compatible parts. Do not reuse damaged wiring or connectors.
• Clean dust: If the smell was mild and due to dust, clean the condenser area and components with a vacuum and brush.
• Professional evaluation: If you are unsure of the source or if multiple components are damaged, have a qualified technician inspect the unit before reuse.
