Possible cause
Power failure; the fuse has been switched
off; the main plug has not been inserted
properly.
Appliance door opened frequently.
Large quantities of fresh food are being
frozen.
The ventilation openings have been
covered.
Temperature has been set too low.
The bulb is defective.
Light switch is sticking.
The freezer compartment door was open
too long. The evaporator (refrigeration
generator) is covered in such a thick layer
of ice that the fully automatic defrosting
system is no longer able to defrost this
amount of ice.
Remedial action
Check whether the power is on, the fuse must be switched on.
Do not open the door unnecessarily.
Do not exceed max. freezing capacity.
Remove obstacles.
Select a warmer temperature (see Selecting the
temperature")
Loosen frozen food with a blunt object. Do not use a knife or
pointed object.
Always ensure that the appliance door is closed.
Replace bulb (see Changing the bulb")
Check whether it can be moved.
Take frozen food out of the appliance, insulate thoroughly and
place in a cool location. After approx. 12 hours the ice in the
refrigerating system has thawed. Switch on the appliance
again and put back the frozen food.
Note!
To prevent loss of refrigeration, do not open the refrigerator
compartment door unnecessarily often.
