Ventilation openings have
been covered.
Too much food was placed in
the freezer compartment at
once.
Appliance opened
frequently.
The ventilation openings
have been covered.
Large quantities of fresh
food are being frozen.

Ensure that there is adequate ventilation.
Do not exceed max. freezing capacity.
When the fault has been eliminated, the alarm

Do not exceed max. freezing capacity.
To defrost the evaporator, remove the frozen
food with the compartments, insulate well
and store in a cool location.

After approx. 20 min. the condensation begins
to run into the evaporation pan,
