The correct temperature
This short-term loss of cooling is no
cause for concern in the following
cases:
– If the appliance doors were left open
for a while, e.g. while loading or
removing a large amount of food.
– If you are freezing fresh food.
If the temperature in the freezer
remains above -18°C (0°F) for a
longer period of time, check that the
frozen food has not started to thaw.
If it has, check that the food is safe
to use and if it is, then use it as soon
as possible.
