OPERATION

Before Use

Notes for Operation

• Users should keep in mind that frost can form if

the door is not closed completely or if the

humidity is high during the summer.

• Ensure there is sufficient space between food

stored on the shelf or door basket to allow the

door to close completely.

• Opening the door for long periods can cause a

significant increase of the temperature in the

compartments of the appliance.

• If the refrigerating appliance is left empty for

long periods, switch off, defrost, clean, dry, and

leave the door open to prevent mould

developing within the appliance.

Door Open Alarm

The alarm sounds 3 times in 30 second intervals if

the door is left open or not completely closed for 1

minute.

NOTE

• Contact the LG Electronics customer information

centre if the alarm sound continues even after

closing all doors.

Failure Detection

The appliance can automatically detect problems

during the operation.

NOTE

• If a problem is detected, the appliance may not

operate and an error code is displayed even

when any button is pressed.

• If an error code is indicated on the display, do

not turn off the power. Immediately contact the

LG Electronics customer information centre and

report the error code. If you turn off the power,

the repair technician from the our information

centre may have difficulty finding the problem.

Suggestion for Energy Saving

• For the most efficient use of energy, make sure

that door bins, drawers and shelves are

assembled properly.

• Ensure there is sufficient space between stored

foods. This allows cold air to be circulated evenly

and lowers electricity bills.

• Store hot food only after it has cooled in order to

prevent dew or frost.

• When storing food in the freezer compartment,

set the freezer temperature lower than the

temperature indicated on the food.

• Do not set the temperature of the appliance

lower than needed.

• Do not put food near the temperature sensor of

the fridge compartment. Keep a distance of at

least 3 cm from the sensor.

• Note that a temperature rise after defrosting has

a permissible range in the appliance

specifications. If you wish to minimise the impact

on the food storage due to a temperature rise,

seal or wrap the stored food in several layers.

• The automatic defrosting system in the

appliance ensures that the compartment

remains free of ice buildup under normal

operating conditions.

Storing Foods Effectively

• Food may freeze or spoil if stored at the wrong

temperature. Set the refrigerator to the correct

temperature for the food being stored.

• Store frozen food or refrigerated food inside

sealed containers.

• Check the expiration date and label (storage

instructions) before storing food in the

appliance.

OPERATION

ENGLISH

• Do not store food for a long period of time if it

spoils easily at a low temperature.

• Do not place unfrozen food in direct contact with

food that is already frozen. It could be necessary

to reduce the quantity to be frozen if freezing

every day is anticipated.

• Place the refrigerated food or frozen food in

each fridge or freezer compartment

immediately after purchasing.

• Store raw meat and fish in suitable containers in

the refrigerator, so that it is not in contact with or

drip onto other food.

• Refrigerated foods and other food items can be

stored on top of the vegetable drawer.

• Avoid refreezing any food which has been

completely thawed. Freezing any food which has

been completely thawed again will lower its taste

and nutrition.

• Do not overfill the appliance. Cold air can not

circulate properly if the appliance is overfilled.

• Cool hot food before storing. If too much hot

food is placed inside, the internal temperature of

the appliance can increase and negatively affect

other foods stored in the appliance.

• If you set an excessively low temperature for

food, it may become frozen. Do not set a

temperature lower than the required

temperature for the food to be stored correctly.

• If there are chill compartments in the appliance,

do not store vegetables and fruits with higher

moisture content in the chill compartments as

they may freeze due to the lower temperature.

• In the event of a blackout, call the electricity

company and ask how long it is going to last.

- You should avoid door openings while the

power is off.

- When the power supply gets back to normal,

check the condition of the food.

CAUTION

• Keep children away from the dispenser to

prevent children playing with or damaging the

controls.

OPERATION

CAUTION

• Throw away the first few batches of ice (about 20

cubes and 7 cups of water). This is also necessary

if the appliance has not been used for a long

time.

• Clean the water dispensing system if they have

not been used for 48 hours. Flush the water

system connected to a water supply if water has

not been drawn for 5 days.

• To clean the water dispensing system, flush the

water through the dispenser about 5 minutes

and throw away the first few batches of ice.

• Do not use a thin crystal cup or chinaware when

dispensing water or ice.

NOTE

• If you open the freezer door while water is being

Automatic Icemaker

This feature is only available on some models.

OPERATION

ENGLISH

This feature may vary depending on model

purchased.

Before Using the In-Door

Icemaker

• The icemaker produces ice normally when

approximately 48 hours have passed after the

appliance is initially installed.

• If the ice bin is completely filled with ice, ice

production will stop.

• Sound of ice dropping into the ice bin is normal.

• If ice cubes are stored in the ice bin for a long

period of time, they may clump together and

may not be separated easily. In such a case,

empty the ice bin and allow fresh ice to be made.

CAUTION

• It is normal for milky or cloudy water to be

dispensed after replacing the water filter. This

air in the water will clear eventually and is safe to

drink.

• The first ice and water dispensed may include

particles or odour from the water supply line or

the water tank.

• If discolored ice is dispensed, check the water

tank and the water supply for a possible source.

If the problem continues, contact the LG

Electronics customer information centre. Do not

use the ice or water until the problem is

corrected.

• Do not touch the ice outlet or the automatic

icemaker with your hand or a tool.

• Dispense ice into a glass before filling it with

water or other beverages. Splashing will occur if

ice is dispensed into a glass that already contains

liquid.

• Never use a glass that is exceptionally narrow or

deep. Ice may jam in the ice passage, affecting

the performance of the appliance.

• Keep the glass at a proper distance from the ice

outlet. A glass held too close to the outlet may

prevent ice from dispensing.

• Dispose of the ice inside the ice bin if you go on

vacation or if an extended power outage occurs.

Water from melting ice may drop from the

dispenser onto the floor.

In-Door Icemaker

The automatic icemaker can automatically make 70

- 182 cubes at a time, 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.).

MAINTENANCE

ENGLISH

MAINTENANCE

Cleaning

General Cleaning Tips

• Performing manual defrosting, maintenance or

cleaning of the appliance while food is stored in

the freezer can raise the temperature of the food

and reduce its storage life.

• Regularly clean any surfaces that can come in

contact with food.

• When cleaning the inside or outside of the

appliance, do not wipe it with a rough brush,

toothpaste, or flammable materials. Do not use

cleaning agents containing flammable

substances. This may cause discolouration or

damage to the appliance.

- Flammable substances: alcohol (ethanol,

methanol, isopropyl alcohol, isobutyl alcohol,

etc.), thinner, bleach, benzene, flammable

liquid, abrasive, etc.

• After cleaning, check if the power cable is

damaged.

Cleaning the Exterior

• When cleaning the outside air vents of the

appliance by means of vacuuming, then the

power cord should be unplugged from the outlet

to avoid any static discharge that can damage

the electronics or cause an electric shock.

Regular cleaning of the rear and side ventilation

covers is recommended to maintain reliable and

economical operation of the unit.

• Keep the air vents on the exterior of the

appliance clean. Blocked air vents can cause fire

or appliance damage.

• For the appliance exterior, use a clean sponge or

soft cloth and a mild detergent in warm water.

Do not use abrasive or harsh cleaners. Dry

thoroughly with a soft cloth. Do not use

contaminated cloths when cleaning the stainless

steel doors. Always use a dedicated cloth and

wipe in the same direction as the grain. This

helps reduce surface staining and tarnishing.

Cleaning the Interior

• When removing a shelf or drawer from inside

the appliance, remove all stored foods from the

shelf or drawer to prevent injury or damage to

the appliance. Otherwise, injury may occur due

to the weight of stored foods.

• Detach the shelves and drawers and clean them

with water, and then dry them sufficiently,

before replacing them.

• Regularly wipe the door gaskets with a wet soft

towel.

• Door basket spills and stains should be cleaned

as they can compromise storage ability of the

basket and could even be damaged.

• Never clean the shelves or containers in the

dishwasher. The parts may become deformed

due to the heat.

Cleaning the Condenser Cover

Use a vacuum cleaner with a brush to clean the

condenser cover and vents. Do not remove the

panel covering the condenser coil area.

We recommend that this be done every 12 months

to maintain operating efficiency.

Ice & Water

Symptoms Possible Cause & Solution

The automatic

icemaker does not

produce ice or

produces a small

amount of ice.

Did you install the appliance recently?

• The ice maker produces ice normally when approximately 48 hours have

passed after the appliance is installed.

• If the fridge compartment temperature is too cold, the water filter can

freeze and block the water flow to the ice maker.

Did you connect the water supply pipe to the appliance and open the

supply valve?

• Connect the water supply pipe to the appliance and open the supply valve

completely.

Is the water supply hose bent?

• If the water supply hose is bent, the water flow could be compromised.

Have you dispensed a large amount of ice recently?

• It takes approximately 24 hours to produce more ice in the automatic

icemaker. Please wait.

Did you set the ice maker switch or the automatic icemaker button on

the control panel to ON?

• Press I on the automatic icemaker switch or set

for the automatic

icemaker button on the control panel. (For more details on how to use, visit

LG Electronics website or use your smart device.)

Is the temperature of the freezer compartment set too high?

• If the set temperature is too warm, ice will be produced slowly or not at all.

Set the Freezer temperature to -18 °C for normal operation of the

automatic icemaker.

Have you been opening the appliance door frequently?

• If you open the appliance door frequently, cold air will escape, lowering

the speed of ice production. Do not open and close the appliance door

frequently.

Is the appliance door completely closed?

• If the appliance door is not completely closed, the temperature of the

freezer compartment will increase, slowing down the ice production

speed. Close the appliance door completely.

Ice is not dispensed. Unable to hear the sound of ice coming out?

• In the control panel, select the modes for cubed ice and crushed ice

alternately to dispense the ice.

Is the ice path blocked? (You can check the ice passage by separating the

ice bin.)

• Ice may not be dispensed properly if the ice passage is blocked. Check the

ice and clean the ice path regularly.

TROUBLESHOOTING

Water does not come

out.

The supply valve may be turned off. (For Plumbed models Only)

• Open the water supply valve.

• Check if the fridge compartment temperature is too cold, as the water

filter can freeze and block the water flow to the dispenser.

The water dispenser tank may be empty. (Non plumbed models only)

• Fill the water dispenser tank.

Is the water supply valve closed? (For Plumbed models Only)

• Open the water supply valve.

Are you using unfiltered water?

• Unfiltered water can contain a large amount of various heavy metals or

foreign substances, so the filter may be clogged in the early stage

regardless of the life of the filter.

Water tastes strange. Is the taste of water different when comparing it with the taste of water

from the previous water purifier?

• Has the purified water or cold water not been used for an extended period

of time?

Has it been a long time since you installed and replaced the filter?

• If an expired filter is used, the purification performance may decline. It is

recommended to replace the filter according to the filter replacement

period.

Have you flushed out the filter properly in the initial stage after

installing it?

• When you install or replace the filter for the first time, you need to remove

air and activated carbon residue from inside the filter. Use the appliance

after dispensing and discharging approximately 5 litres of purified water

from the dispenser by pressing the water dispensing lever. (Activated

carbon is harmless to humans.)

Has the purified water or cold water not been used for an extended

period of time?

• The taste of old water may change due to bacterial growth. Use the

product after dispensing and discharging approximately 5 litres

(approximately three minutes) from the water dispenser.
