Display shows E8 and the compressor does not start or stops shortly after starting.

Safety: Unplug the cooler. Work carefully around the sealed refrigeration system; do not cut or open refrigerant lines.

• Access compressor area: Remove the rear lower panel to expose the compressor, start relay, and overload protector.
• Listen and feel: When briefly powered (then unplugged again), a clicking sound from the relay or overload followed by compressor silence suggests a start fault.
• Inspect components: Remove the plastic cover on the compressor terminals. Check the PTC start relay and overload protector for burn marks, cracks, or loose fit.
• Replace start components: If visually damaged or if E8 persists, replace the start relay and overload protector with mQuvée‑specified parts.
• Check wiring: Ensure all spade connectors are tight on the compressor terminals and that the earth (ground) connection is secure.
• Test run: Reassemble covers, restore power, and monitor compressor operation. If the compressor still fails to start and E8 returns, the compressor itself may be locked or internally damaged.
• Compressor replacement: Replacing a sealed compressor requires specialized tools and refrigerant handling certification. Contact an authorized refrigeration technician.
