I need to learn how to control the tempature setting

Hello,

The temperature controls are located at the top front of the refrigerator or freezer compartments.
The recommended setting should be correct for normal household refrigerator use. The controls are correctly set when milk or juice is as cold as you like and when ice cream is firm.
Wait 24 hours for your refrigerator to completely cool before adding food. If you add food before the refrigerator has completely cooled, your food may spoil.
NOTE: Adjusting the refrigerator and freezer temperature controls to a colder-than-recommended setting will not cool the compartments any faster.
If the temperature is too warm or too cold in the refrigerator or freezer, first check the air vents to be sure they are not blocked before adjusting the controls.
To turn Off/On:
Style 1 Press the freezer down arrow touch pad until a dash (-) appears in both the refrigerator and freezer displays. Neither compartment will cool.
Style 2 Turn the freezer control to the word Off. Neither compartment will cool when the freezer is set to Off.

Energy Saver option (on some models)
The Energy Saver option turns off the heater which helps to reduce moisture on the door hinge seal. The refrigerator uses more energy when Energy Saver is off.
Press the control to On to save energy when the environment is less humid.
Press the control to Off when the environment is warm and more humid, or if you notice moisture on the door hinge seal.

Adjusting controls
If you need to adjust the temperature in either the refrigerator or freezer compartment.
NOTES:
For Style 1 control, press the up and down arrow touch pads; for Style 2 controls, turn the dial to adjust the temperature.
Except when starting the refrigerator, do not adjust either control more than one setting at a time.
Wait 24 hours between adjustments for the temperature to stabilize.

Hope this guideline will helpout.....
