Possible cause and remedy
This is not a fault. The set temperature is too high.
 Correct the temperature setting.
 Check the temperature again after 24 hours.
The food begins to defrost.
The room temperature is lower than the ambient
temperature for which the appliance is designed.
Operating in a room which is too cold will cause the
compressor to switch off for too long, causing the
freezer to become too warm.
 See "Installation advice - Location".
 Raise the temperature of the room.
This is not a fault. The electronic unit for the
compressor is equipped with an operation and fault
diagnosis LED indicator light which flashes every 15
seconds (depending on model).
The door seal has come out of its groove.
 Check that the door seal is correctly seated in the
groove.
The door seal is damaged.
 Check if the door seal is damaged.
No tools are required to change the door seal.
