• Never use a glass that is exceptionally narrow or deep. Ice may jam in the ice passage and refrigerator performance may be affected.

Ice and Water Dispenser

Dispenser Structure

Using the Dispenser

NOTE

• To dispense cold water or ice, push on the dispenser paddle with a glass.
• The first ice and water dispensed may include particles or odor from the water supply line or the water tank. Throw away the first few batches of ice (about 140 - 160 cubes). This is also necessary if the refrigerator has not been used for a long time.
• The dispenser will not operate when either of the refrigerator doors is open.
• If discolored ice is dispensed, check the water filter and water supply. If the problem continues, contact an LG Electronics Customer Information Center. Do not use the water or ice until the problem is corrected.
• Dispense ice into a glass before filling it with water or other beverages. Splashing may occur if ice is dispensed into a glass that already contains liquid.
• Some dripping may occur after dispensing. Hold the cup beneath the dispenser for a few seconds after dispensing to catch all of the drops.
• Keep containers at an appropriate distance from the dispensers. Tall, narrow glasses should be held far enough from the ice outlet to prevent ice from jamming in the ice chute. A container with a very small opening should be held as close to the dispenser as possible to avoid spilling.
• Keep the glass at a proper distance from the ice outlet. A glass held too close to the outlet may prevent ice from dispensing.

Locking the Dispenser

Press the Lock button on the control panel for 3 seconds to lock or unlock the dispenser and all of the control panel functions.

Ice Compartment

CAUTION

• Keep hands and tools out of the ice compartment door and dispenser chute. Failure to do so may result in damage or personal injury.

Keep the ice compartment door closed tightly. If the ice compartment door is not closed tightly, the cold air in the ice bin will freeze food in the refrigerator compartment. This could also cause the icemaker to stop producing ice.

In-Door Ice Bin

The icemaker stops producing ice when the in-door ice bin is full. During use, the ice may stack unevenly in the bin, causing the icemaker to misread the number of ice cubes and stop producing ice. Shaking the ice bin to level the ice within it can reduce this problem.

To prevent ice cubes from melting and leaking from the dispenser, ALWAYS empty the ice bin when the icemaker is turned OFF for more than a few hours.

The ice passage may become blocked with frost if only crushed ice is used. Remove the frost that accumulates by removing the ice bin and clearing the passage with a rubber spatula. Dispensing cubed ice can also help prevent frost buildup.

Detaching the In-Door Ice Bin

1. Gently pull the handle to open the ice compartment.
   • 
2. To remove the in-door ice bin, grip the front handle, slightly lift the lower part, and slowly pull out the bin as shown.
   • 

Assembling the In-Door Ice Bin

1. Carefully insert the in-door ice bin, slanting the top slightly to fit it under the icemaker.
   • 
2. Gently push the handle to close the ice compartment.

CAUTION

• When handling the ice bin, keep hands away from the icemaker tray area to avoid personal injury.
• Storing cans or other items in the ice bin will damage the icemaker.
• Never use thin crystal glasses or containers to collect ice. Such containers may chip or break resulting in glass fragments in the ice.
• Avoid touching the auto shutoff (feeler arm) when replacing the ice bin. See the label on the ice compartment door for details.
• 

Automatic Icemaker

In-Door Icemaker

NOTE

• Ice is made in the automatic in-door icemaker and sent to the dispenser. The icemaker produces 70 - 182 cubes in a 24-hour period, depending on freezer compartment temperature, room temperature, number of door openings and other operating conditions.
• It takes about 12 to 24 hours for a newly installed refrigerator to begin making ice.
• Ice-making stops when the in-door ice bin is full. When full, the in-door ice bin holds approximately 6 to 8 (12-16 oz.) glasses of ice.
• Foreign substances or frost on the ice-detecting sensor can interrupt ice production. Make sure the sensor area is clean at all times for proper operation.
• To increase ice production, use the Ice Plus function. The function increases both ice making and freezing capabilities.

Freezer Icemaker

NOTE

• The automatic freezer icemaker produces 12 cubes at a time, 50-110 pieces within a 24 hour period if conditions are favorable. This amount may vary according to the environment (ambient temperature around the appliance, frequency of the door being opened, amount of food stored in the appliance, etc.).
• If the ice bin is completely filled with ice, ice production will stop.
• Sound of ice dropping into the ice bin is normal.
• The icemaker produces ice once approximately 48 hours have passed after the appliance is initially installed.
• Discard the first ice cubes produced after initial install.
• Ice cubes which are stored in the ice bin for a long time may clump together and be difficult to separate. If this happens, empty the ice bin completely and clean it before reinstalling it.

WARNING Personal Injury Hazard

• DO NOT place fingers or hands on the automatic ice making mechanism while the refrigerator is plugged in.
• To avoid personal injury, keep hands out of the ice door and passage.

CAUTION Never store beverage cans or other items in the ice bin for the purpose of rapid cooling. Doing so may damage the icemaker or the containers may burst.

Turning the Automatic Icemakers On or Off

To turn off one of the automatic icemakers, set the icemaker switch to OFF (O). To turn on the automatic icemaker, set the switch to ON (I).

Normal Sounds You May Hear

• Keeping the power turned on to the icemakers before the water line is connected can damage the icemakers.

• The icemaker water valve will buzz as the icemaker fills with water. If the power switch is in the ON (I) position, it will buzz even if it has not yet been hooked up to water. To stop the buzzing, move the power switch to OFF (O).
• You will hear the sound of cubes dropping into the bin and water running in the pipes as the icemaker refills.

NOTE • Do not keep the power turned on to the icemakers if the water line is not connected. Doing so can damage the icemakers.

Preparing for Vacation

Set both icemaker power switches to OFF (O) and shut off the water supply to the appliance. If the ambient temperature will drop below freezing, have a qualified technician drain the water supply system to prevent serious property damage due to flooding caused by ruptured water lines or connections.

NOTE The ice bin should be emptied any time the power switch is turned to the OFF (O) position.

Storing Food

Depending on the model, some of the following functions may not be available.

Each compartment inside the refrigerator is designed to store different types of food. Store food in the optimal space to enjoy the freshest taste.

CAUTION

• Do not overfill or pack items too tightly into door bins. Doing so may cause damage to the bin or personal injury if items are removed with excessive force.
• Do not store glass containers in the freezer. Contents may expand when frozen, break the container and cause injury.

NOTE

• If you are leaving home for a short period, like a short vacation, the refrigerator should be left on. Refrigerated foods that are able to be frozen will stay preserved longer if stored in the freezer.
• If you are leaving the refrigerator turned off for an extended period, remove all food and unplug the power cord. Clean the interior, and leave the doors open to prevent fungi from growing in the refrigerator.
• Do not store food with high moisture content towards the top of the refrigerator. The moisture could come in direct contact with the cold air and freeze.
• Wash food before storing it in the refrigerator. Vegetables should be washed, and food packaging should be wiped down to prevent adjacent foods from being contaminated.
• If the refrigerator is kept in a hot and humid place, frequent opening of the door or storing a lot of vegetables in the refrigerator may cause condensation to form. Wipe off the condensation with a clean cloth or a paper towel.
• If the refrigerator door or freezer drawer is opened or closed too often, warm air may penetrate the refrigerator and raise its temperature. This can increase the running costs of the unit.

Food Storage Tips

Wrap or store food in the refrigerator in airtight and moisture-proof material unless otherwise noted. This prevents food odor and taste transfer throughout the refrigerator. For dated products, check date code to ensure freshness.

1. Butter or Margarine
   • Keep opened butter in covered dish or closed compartment. When storing an extra supply, wrap in freezer packaging and freeze.
2. Cheese
   • Store in original wrapping until used. Once opened, rewrap tightly in plastic wrap or aluminum foil.
3. Milk
   • Wipe milk cartons. For coldest milk, place containers on an interior shelf.
4. Eggs
   • Store in original carton on interior shelf, not on door shelf.
5. Fruit
   • Do not wash or hull fruit until it is ready to be used. Sort and keep fruit in original container in a crisper, or store in completely closed paper bag on refrigerator shelf.
6. Leafy Vegetables
   • Remove store wrapping, trim or tear off bruised and discolored areas, wash in cold water, and drain. Place in plastic bag or plastic container and store in crisper.
7. Vegetables with skins(carrots,peppers)
   • Place in plastic bags or plastic container and store in crisper.
8. Fish
   • Freeze fresh fish and shellfish if they are not being eaten the same day purchased. Eating fresh fish and shellfish the same day purchased is recommended.
9. Leftovers
   • Cover leftovers with plastic wrap or aluminum foil, or store in plastic containers with tight lids.

Storing Frozen Food

Check a freezer guide or a reliable cookbook for further information about preparing food for freezing or food storage times.

Freezing

Your freezer will not quick-freeze a large quantity of food. Do not put more unfrozen food into the freezer than will freeze within 24 hours (no more than 2 to 3 pounds of food per cubic foot of freezer space). Leave enough space in the freezer for air to circulate around packages. Be careful to leave enough room at the front so the door can close tightly.

Storage times will vary according to the quality and type of food, the type of packaging or wrap used (how airtight and moisture-proof) and the storage temperature. Ice crystals inside a sealed package are normal. This simply means that moisture in the food and air inside the package have condensed, creating ice crystals.

NOTE Allow hot foods to cool at room temperature for 30 minutes, and then package and freeze. Cooling hot foods before freezing saves energy.

Packaging

Successful freezing depends on correct packaging. When you close and seal the package, it must not allow air or moisture in or out. If it does, you could have food odor and taste transfer throughout the refrigerator and could also dry out frozen food.

Packaging recommendations

• Rigid plastic containers with tight-fitting lids
• Straight-sided canning/freezing jars
• Heavy-duty aluminum foil
• Plastic-coated paper
• Non-permeable plastic wraps
• Specified freezer-grade self-sealing plastic bags Follow package or container instructions for proper freezing methods.

Do not use

• Bread wrappers
• Non-polyethylene plastic containers
• Containers without tight lids
• Wax paper or wax-coated freezer wrap
• Thin, semi-permeable wrap

Durabase®

The Durabase® divider allows you to organize the Durabase® area into sections. It can be adjusted from side to side to accommodate items of different sizes.

WARNING If the Durabase® divider is removed, there is enough open space for children or pets to crawl inside. To prevent accidental child and pet entrapment or suffocation risk, DO NOT allow children or pets to touch or go near the drawer.

Wireless LAN Module Specifications

Smart Grid Function

When the refrigerator operates in Smart Grid mode, the Smart Refrigerator function can control energy usage or delay the operation of some functions to save energy during peak usage periods.

• You can override the Smart Grid function any time (using the Smart Grid button or application).
• To use the Smart Grid function, you need to register your appliance with your electric utility company

Smart Grid Application Features

Smart Saving_Demand Response

You can lower energy usage based on Demand Response (DR) signals from the utility company. If the refrigerator is operating in Smart Saving mode according to the DR signal, you can see a pop up.

Seasonal Energy

Savings Lower energy usage based on time period.

Using the Smart Grid Function

This feature responds to notification events from your utility company to run high energy consuming tasks during off-peak periods when demand is lower. These notification events are known as Demand Response signals. If the refrigerator receives a Demand Response signal from the utility company, the refrigerator will turn on the Grid LED on the refrigerator display and control its power consumption according to the signal.

The refrigerator will respond to the signals received from the utility company as long as product performance is maintained. If the refrigerator receives a Demand Response signal, the refrigerator will operate in Delay Appliance Load (DAL) or Temporary Appliance Load Reduction (TALR) mode.

Delay Appliance Load (DAL)

The refrigerator responds to a DAL signal by providing a moderate load reduction for the duration of the delay period. This mode controls functions that consume a lot of energy such as adjusting the cooling system, running the defrost cycle, and making ice.

• When the refrigerator operates in DAL mode, the Grid LED is illuminated on the refrigerator display.
• DAL mode is automatically deactivated after the period stipulated by the DAL signal (max. 4 hours) or when you override the Smart Grid function.

Temporary Appliance Load Reduction (TALR)

The refrigerator responds to a TALR signal by aggressively reducing the load for a short time period, typically 10 minutes. This mode reduces energy consumption by stopping the compressor and controlling the functions that consume a lot of energy such as the defrost cycle and fan.

• When the refrigerator operates in TALR mode, the Grid LED is illuminated on the refrigerator display.
• TALR mode is automatically deactivated after the received duration (max. 10 minutes), or when you override the Smart Grid function. The mode is immediately deactivated and the refrigerator returns to its normal state when the door is opened or closed, or the dispenser is used.

Override Smart Grid

Mode To ignore the Demand Response signal from the utility company and override the Smart Grid function, push the Smart Grid button while the refrigerator is in Smart Grid mode. When you override the Smart Grid function, the refrigerator ignores the Demand Response signal and is no longer controlled by the utility company until the next Demand Response signal is sent. You can also override the Smart Grid function using the smart phone app.

1. Refrigerator and Freezer section are not cooling.
   • The refrigerator control is set to OFF (some models).
     • Turn the control ON. Refer to the Setting the Controls section for proper temperature settings.
   • Refrigerator is set to Demo Mode.
     • Demo Mode allows the lights and control display to work normally while disabling cooling, to save energy while the refrigerator is on the showroom floor. See the FAQs section of this manual for instructions on how to disable Demo Mode.
   • Refrigerator is in the defrost cycle.
     • During the defrost cycle, the temperature of each compartment may rise slightly. Wait 30 minutes and confirm the proper temperature has been restored once the defrost cycle has completed.
   • Refrigerator was recently installed.
     • It may take up to 24 hours for each compartment to reach the desired temperature.
   • Refrigerator was recently relocated.
     • If the refrigerator was stored for a long period of time or moved on its side, it is necessary for the refrigerator to stand upright for 24 hours before connecting it to power.
2. Cooling system runs too much.
   • Refrigerator is replacing an older model.
     • Modern refrigerators require more operating time but use less energy due to more efficient technology.
   • Refrigerator was recently plugged in or power restored.
     • The refrigerator will take up to 24 hours to cool completely.
   • The door is opened often or a large amount of food / hot food was added.
     • Adding food and opening the door warms the refrigerator, requiring the compressor to run longer in order to cool the refrigerator back down. In order to conserve energy, try to get everything you need out of the refrigerator at once, keep food organized so it is easy to find, and close the door as soon as the food is removed. (Refer to the Food Storage Guide.)
   • Doors are not closed completely.
     • Firmly push the doors shut. If they will not shut all the way, the "Doors will not close correctly or pop open" section.
   • Refrigerator is installed in a hot location.
     • The compressor will run longer under warm conditions. At normal room temperatures (70 °F) expect your compressor to run about 40 % to 80 % of the time. Under warmer conditions, expect it to run even more often. The refrigerator should not be operated above 110 °F.
   • Condenser / back cover is clogged.
     • Use a vacuum cleaner with an attachment to clean the condenser cover and vents. Do not remove the panel covering the condenser coil area.
3. Interior moisture buildup.
   • Doors are opened often or for long periods of time.
     • When the doors are opened often or for long periods of time, warm, humid air enters the compartment. This raises the temperature and moisture level within the compartment. To lessen the effect, reduce the frequency and duration of door openings.
   • Doors are not closed correctly.
     • See the "Doors will not close correctly or pop open" section.
   • Weather is humid.
     • Humid weather allows additional moisture to enter the compartments when the doors are opened leading to condensation or frost. Maintaining a reasonable level of humidity in the home will help to control the amount of moisture that can enter the compartments.
   • Defrost cycle recently completed.
     • During the defrost cycle, the temperature of each compartment may rise slightly and condensation may form on the back wall. Wait 30 minutes and confirm that the proper temperature has been restored once the defrost cycle has completed.
   • Food is not packaged correctly.
     • Food stored uncovered or unwrapped, and damp containers can lead to moisture accumulation within each compartment. Wipe all containers dry and store food in sealed packaging to prevent condensation and frost.
4. Food is freezing in the refrigerator compartment.
   • Food with high water content was placed near an air vent.
     • Rearrange items with high water content away from air vents.
   • Refrigerator temperature control is set incorrectly.
     • If the temperature is too cold, adjust the control one increment at a time and wait for the temperature to stabilize. Refer to the Control Panel section for more information.
   • Refrigerator is installed in a cold location.
     • When the refrigerator is operated in temperature below 41°F (5°C), food can freeze in the refrigerator compartment. The refrigerator should not be operated in temperature below 55°F (13°C).
5. Refrigerator or Freezer section is too warm.
   • Refrigerator was recently installed.
     • It may take up to 24 hours for each compartment to reach the desired temperature.
   • The air vents are blocked. Cold air circulates from the freezer to the fresh food section and back again through air vents in the wall dividing the two sections.
   • Locate air vents by using your hand to sense airflow and move all packages that block vents and restrict airflow. Rearrange items to allow air to flow throughout the compartment.

Cooling/Ice & Water

1. Refrigerator or Freezer section is too warm.
   • Doors are opened often or for long periods of time.
