Clicking sound from the back; compressor tries to start but shuts off repeatedly, no ice produced.

Safety first: Unplug the unit before accessing compressor components.

• Improve ventilation: Ensure adequate space around the unit and clean dust from vents to reduce compressor temperature.
• Check power source: Avoid using long extension cords or power strips. Plug directly into a properly grounded wall outlet.
• Inspect start relay: Remove the rear panel and gently pull off the compressor start device. Check for rattling pieces inside or burn marks. Replace if suspect.
• Allow cool-down: Let the unit sit unplugged for at least 30 minutes, then retry. Persistent clicking usually indicates a failing compressor or start device.
• If new relay doesn’t help: The compressor is likely failing internally. Sealed system replacement is complex and often not economical; consider professional diagnosis or replacement of the unit.
