Freezer shows AL04 and may stop cooling or enter a protective mode.

Safety first: Unplug the freezer and allow hot components to cool before touching.

Ventilation checks:

• Ensure there is adequate clearance around the freezer as specified in the Indesit manual (typically several centimeters at sides, rear, and top).
• Remove any objects blocking the rear or top ventilation grilles.

Condenser cleaning:

• Access the rear of the appliance and locate the condenser (black metal grid or coil).
• Use a soft brush and vacuum to remove dust and lint from the condenser surface.

Fan check (if equipped):

• If your model has a condenser fan near the compressor, verify that it spins freely and runs when the compressor is on.
• Replace a seized or non-running fan motor with the correct Indesit condenser fan assembly.

After cleaning and repairs: Restore power and monitor operation. If AL04 recurs despite good ventilation and a clean condenser, the compressor or control board may be overheating and should be assessed by a technician.
