The controls on your refrigerator will look like the following:

Control Settings
Initially, set the refrigerator control to the recommended setting. Allow 24 hours for the temperature to stabilize.
Several adjustments may be required. Adjust the refrigerator control one increment at a time and allow 12 hours after each adjustment for the refrigerator to reach the temperature you have set.
Setting the refrigerator control to Off stops cooling in both the freezer and refrigerator compartments but does not shut off electrical power to the refrigerator.
Control settings will vary based on personal preferences, usage and operating conditions, and may require more than one adjustment. Factors that affect temperature include the amount of food in the refrigerator or freezer, the frequency of door opening and the temperature of food when it is placed in the refrigerator.
Not all features are on all models.
Rearranging the Shelves
Shelves in the refrigerator and freezer compartments are adjustable.
REFRIGERATOR COMPARTMENT
Full Width Shelves
The shelf rests on a molded side-wall support and locks into a track on the rear cabinet wall on each side.

Fruit and Vegetable Crispers
Excess water that may accumulate in the bottom of the drawers or under the drawers should be wiped dry.

Adjustable Humidity Crisper
Slide the control all the way to the Vegetables setting to provide high humidity recommended for most vegetables.
Slide the control all the way to the Fruits setting to provide lower humidity levels recommended for most fruits.

Snack Pan
This pan can be moved to the most useful location for your family’s needs.
To remove, slide the pan out to the stop position, lift the pan up and past the stop position, and lift out.

Crisper Removal
Unload the bottom shelf before attempting to remove the storage drawers.
To remove:
Lift the drawers up slightly while pulling them past the stop location.
If the door prevents you from taking out the drawers, first try to remove the door bins. If this does not offer enough clearance, the refrigerator will need to be rolled forward until the door opens enough to slide the drawers out. In some cases, when you roll the refrigerator out, you will need to move the refrigerator to the left or right as you roll it out.

To remove the glass cover:
Remove the glass, then the frame. When replacing the glass, push the front edge firmly into the frame.

To remove the frame:

A newly-installed refrigerator may take 12-24 hours to begin making ice.
Automatic Icemaker (on some models)
CAUTION: Avoid contact with the moving parts of the ejector mechanism, or with the heating element (located on the bottom of the ice maker) that releases the cubes. Do not place fingers or hands on the automatic ice making mechanism while the refrigerator is plugged in.

The icemaker will produce approximately 3 to 3-1/2 lbs. (1.36 to 1.59 kg) of ice in a 24-hour period, depending on the freezer compartment temperature, room temperature, number of door openings and other use conditions.
If the refrigerator is operated before the water connection is made to the icemaker, move the power switch to OFF.
When the refrigerator has been connected to the water supply, set power switch to ON
The icemaker will fill with water when it cools to 15°F (-9°C). A newly-installed refrigerator may take 12 to 24 hours to begin making ice cubes.
Once the icemaker starts to make ice, it may take up to 48 hours to fill the bin, depending on the temperature settings and number of door openings.
You will hear a buzzing sound each time the icemaker fills with water.
Throw away the first few batches of ice to allow the water line to clear.
Be sure nothing interferes with the sweep of the feeler arm.
When the bin fills to the level of the feeler arm, the icemaker will stop producing ice.
It is normal for several cubes to be joined together.
If ice is not used frequently, old ice cubes will become cloudy, taste stale, shrink or fuse together.
NOTE: In homes with lower-than-average water pressure, you may hear the icemaker cycle multiple times when making one batch of ice.
Icemaker Accessory Kit
If your refrigerator did not already come equipped with an automatic icemaker, an icemaker accessory kit is available at extra cost.
Check the back of the refrigerator for the specific ice maker kit needed for your model.
The door handles and trim. Clean with a cloth dampened with soapy water. Dry with a soft cloth.
Keep the outside clean. Wipe with a clean cloth lightly dampened with kitchen appliance wax or mild liquid dish detergent. Dry and polish with a clean, soft cloth.
The stainless steel panels and door handles (on some models) can be cleaned with a commercially available stainless steel cleaner. Cleaners with oxalic acid such as Bar Keepers Friend Soft Cleanser will remove rust, tarnish, and small blemishes Use only a liquid cleanser free of grit and rub in the direction of the brush lines with a damp soft sponge. Do not use appliance wax or polish on the stainless steel.
Do not wipe the refrigerator with a soiled dish cloth or wet towel. These may leave a residue that can erode the paint. Do not use scouring pads, powdered cleaners, bleach or cleaners containing bleach because these products can scratch and weaken the paint finish.
To help prevent odors, leave an open box of baking
soda in the fresh food and freezer compartments.
Unplug the refrigerator before cleaning.
If this is not practical, wring excess moisture out of sponge or cloth when cleaning around switches, lights or controls.
Use warm water and baking soda solution—about a tablespoon (15 ml) of baking soda to a quart (1 liter) of water. This both cleans and neutralizes odors. Rinse and wipe dry.
Do not clean with any products containing detergent, bleach or ammonia. They may damage the refrigerator.
After cleaning the door gaskets, apply a thin layer of petroleum jelly to the door gaskets at the hinge side. This helps keep the gaskets from sticking and bending out of shape. Do not use cleansing powders or other abrasive cleaners.
CAUTION: Do not clean glass shelves or covers with warm water when they are cold. Glass shelves and covers may break if exposed to sudden temperature changes or impact such as bumping or dropping. Tempered glass is designed to shatter into many small pieces if it breaks.
Do not wash any plastic refrigerator parts in the dishwasher.
Condenser
Depending on the model, the condenser is either located near the compressor or behind the back wall. For condensers near the compressor, there is no need for routine condenser cleanings in normal home operating environments. However, in environments that may be particularly dusty or greasy, the condenser should be cleaned periodically for efficient refrigerator operation.
Cleaning the condenser:
Sweep away or vacuum up dust.
Be careful when moving the refrigerator away from the wall. All types of floor coverings can be damaged, particularly cushioned coverings and those with embossed surfaces.
Turn the leveling legs at each front corner of the refrigerator counterclockwise until the rollers support the refrigerator. Pull the refrigerator straight out and return it to position by pushing it straight in.
Moving the refrigerator in a side direction may result in damage to the floor covering or refrigerator.
After rolling the refrigerator back into place, turn the legs clockwise until the legs again bear the weight of the refrigerator.
For long vacations or absences, remove food and unplug the refrigerator. Move the refrigerator control to the OFF position and clean the interior with a baking soda solution of one tablespoon (15 ml) of baking soda to one quart (1 liter) of water. Leave the doors open.
Set the icemaker power switch to the OFF position and shut off the water supply to the refrigerator.
If the temperature can drop below freezing, have a qualified servicer drain the water supply system (on some models) to prevent serious property damage due to flooding.
Preparing to Move
Secure all loose items such as grille, shelves and drawers by taping them securely in place to prevent damage. To prevent the doors from opening while moving, secure them to the case with tape. Be sure the refrigerator stays in an upright position during moving.
Setting the refrigerator control to OFF does not remove power to the light circuit.

Newer refrigerators sound different from older refrigerators. Modern refrigerators have more features and use newer technology
Do you hear what I hear? These sounds are normal.
HUMMM... WHOOSH...
The new high efficiency compressor may run faster and longer than your old refrigerator and you may hear a high-pitched hum or pulsating sound while it is operating.
You may hear a whooshing sound when the doors close. This is due to pressure equalizing within the refrigerator.
WHIR! 
You may hear the fans spinning at high speeds. This happens when the refrigerator is first plugged in, when the doors are opened frequently or when a large amount of food is added to the refrigerator or freezer compartments. The fans are helping to maintain the correct temperatures.
CLICKS, POPS, CRACKS and CHIRPS
WATER SOUNDS
