the freezer door is opened to 

often

Air circulation at the back of the

in  the  socket  by  plugging  in            

another electric device, such as 

a night lamp,

make sure the ambient tempera-

ture is not below +10°C

the  appliance  is  designed  for 

operation  in  temperatures  from 

+10°C to +32°C,

decrease  the  frequency  of        

opening the door
