Freezer not cooling at all; interior at room temperature, light may work but no cold air.

Safety first: Unplug the freezer before removing any covers. Do not attempt sealed-system repairs yourself.

• Listen for compressor: With the unit plugged in, listen at the back. If the compressor is silent and you do not hear a low hum or occasional click, it may not be starting.
• Check control settings: Ensure the freezer is switched on and not in a demo or standby mode. Set temperature to the coldest setting.
• Inspect start relay: Remove the rear lower cover and check the compressor start relay and overload for burning or rattling. Replace with an Ariston-compatible start device if suspect.
• Verify power: Confirm the outlet has power and the plug is firmly inserted.

When to call a technician: If the compressor still does not run or runs but no cooling occurs, a professional must check the compressor and refrigerant system.
