Meat should be stored at a temperature
just below the freezing point of water (32˚F,
0˚C) for maximum fresh storage time.

Solution

This is normal. The refrigerator goes on
and off to keep the temperature constant.

Set the refrigerator control to a colder
setting.

A refrigerator requires some hours to
cool down completely.

Wait until the refrigerator or freezer
has a chance to reach its selected 
temperature.

Warm air enters the refrigerator/ freezer
whenever the door is opened.
Open the door less often.

Set the freezer or refrigerator control to a
colder  setting until the freezer or
refrigerator temperature is satisfactory. 

Set the freezer or refrigerator control to
a colder setting until the freezer or
refrigerator temperature is satisfactory.

It is normal for ice crystals to form due
to the moisture content of meat.

Set the refrigerator control to a
warmer setting

See above solution.

Set the freezer control to a warmer
setting until the freezer temperature is
satisfactory.

Close the door completely.

Temperature in the

refrigerator is too

cold and the freezer

temperature 

is  satisfactory.
