WARNING !

IMPORTANT SAFETY NOTICE

The information in this service guide is intended for use by individuals possessing adequate backgrounds
of electrical, electronic, and mechanical experience. Any attempt to repair a major appliance may result in
personal injury and property damage. The manufacturer or seller cannot be responsible for the
interpretation of this information, nor can it assume any liability in connection with its use.

RECONNECT ALL GROUNDING DEVICES

If grounding wires, screws, straps, clips, nuts, or washers used to complete a path to ground are

removed for service, they must be returned to their original position and properly fastened.

IMPORTANT

Electrostatic Discharge (ESD)

Sensitive Electronics

ESD problems are present everywhere. ESD may damage or weaken the electronic
control assembly. The new control assembly may appear to work well after repair is
finished, but failure may occur at a later date due to ESD stress.

■

Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted
metal in the appliance.

- OR -

Touch your finger repeatedly to a green ground connection point or unpainted metal
in the appliance.

■

Before removing the part from its package, touch the anti-static bag to a green ground connection
point or unpainted metal in the appliance.

■

Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.

■

When repackaging failed electronic control assembly in anti-static bag, observe above instructions.

Lower Energy Consumption

Energy is saved by cutting-edge engineering design of drying system
and by optimized heating control. It’s a real money saving.

Reduced drying time

Drying time is shortened by efficient air flow mechanism and
optimized heater.

Innovative noise performance

Noise gets reduced by Noise-absorption & screening technology.

Easy of Use

Wide LED display using electric control.

PROGRAM CYCLE

Time Delay

You can use the Time Delay function to delay the
finishing time of drying cycle.
Maximum Time Delay is 19 hours.
Minimum Time Delay is 3 hours.

1. Turn the dryer on

2. Select cycle

3. Set time delay hour

4. Press Start/Pause button

Favourite

If there is some cycle you would like to make based
on your own drying habit, use “Favourite”.

use next time before changing the stored setting.
For instance, you turn power on and select Extra Dry
in Cotton Cycle and Low temp and Anti-Crease in
series and then lastly press “Favourite” until the
dryer beeps. It’s about 3 seconds. That’s all you have
to do.
The next time, when turning the dryer on and
pressing “Favourite” you can see the above options

Anti-Crease

Anti-Crease is functioning to prevent creases and
rumples that are formed when the laundry is not
unloaded promptly at the end of drying cycle. In
this function, the dryer repeatedly runs and
pauses to the cycle end.
If the door is open during Anti-Crease process,
this function is cancelled.

Drum Light

During operating cycle, you can see the drum
inside by choosing drum light function.
It helps easy viewing the drying cycle.

More Time/Less Time

Press More Time or Less Time until the desired
drying time is set.

Note

These buttons are available only with Timed
Drying, before you push Start/Pause button.

Child Lock ( )

For the safety of your children, press More Time

about 3 seconds. You can see “ ” sign on
LED window.

Note

For “ ” off, press More Time and Less Time
buttons at the same time for about 3 seconds.

Option

Gentle

- These are functioning to shorten or lengthen the
cycle time by increasing or decreasing
temperature.

Damp Dry Beep

- This is a function to inform time.
When is the most suitable for ironing with beeper
sound.

Crease Care

- This is a function to reduce wrinkles.

Buzzer

This is a function to able to adjust volume of

INSTALLATION INSTRUCTIONS

Level the Dryer

1. Leveling the dryer is to prevent undesirable

noise and vibration.

When placing your dryer in an solid and level
area where water is not dripping and freezing,
flammable materials are not stored.

Dryer is raised

Adjustable Feet

2. If the dryer is not properly level, adjust the front
leveling legs up and down as necessary.

Turn them clockwise to raise and
counterclockwise to lower until the dryer is not
wobbling both front-to-back and side-to-side.

Adjustable Feet

Dryer is lowered

Adjustable Feet

Diagonal Check
When pushing down the edges of the machine, the
machine should not move up and down at all.
(Please, check both of two directions)
If machine rocks when pushing the machine top
plate diagonally, adjust the feet again.

INSTALLATION INSTRUCTIONS

Stacking Kit

In order to stack this dryer on LG Washing
machine, you must purchase the LG
stacking kit that is fitted by LG washing
machine top plate size.

1. Place the LG dryer on the LG Washing
machine.

WARNING

When Placing
the dryer, pull
power cord out of
a power source.
Don’t drop the
dryer.

2. Unscrew Rear cover in the Base by unscrewing
2 screws.

Dryer

Washer

3. After detaching protection sheet of double­side tape, align stacking kit holes rear cover
holes and then attach tape to the washer by
pressing hard.

4. Assemble a stacking kit as following.

• Screw 2 screws which is unscrewed earlier to

assemble dryer rear back and stacking kit.( )

• Use accessory screws to assemble washer rear

cover and stacking kit. ( , )

• The procedure for the opposite side will be the

same.

Condensate Drain

The dryer can drain water without delivering to
water container. Water is directly pumped out
of the dryer.

11

6

MAINTENANCE INSTRUCTIONS

Front Ventilation Grille

Vacuum the front ventilation grill 3~4 time a year to
make sure there must be no build-up of lints or dirts
which cause improper intake air flow.

Condensed Water Drain-out

Normally, condensed water is pumped up to water
container where water is collected until emptied.
Not only using water container, but water can be
drained out directly to drain hose especially when
dryer is stacked on top of washing machine.
With connecting kit for drain hose, you can simply
change water path and water reroute to the drainage
facility.
Please follow the below steps.

3. Connect
drain hose
to the kit.

Moisture Sensor?

This device functions to sense the moisture
remaining contents of the laundry during
operation which means it must be cleaned all
the time. The main reason of cleaning this part
is to remove the build-up of lime scale on the
surface of sensor. Wipe the sensors inside
drum (Shown in the picture).

1. Take
connecting
kit out.

2. Separate
water
container
hose from
the kit.

1. Disassemble Top Cover, Drawer and Control

Panel Assembly as explained in Page no. 30

2. Disconnect the Red Connector.

4. Open the Door, Put your one hand inside

the Drum and unscrew the screw on Lamp
Cover with the help of a screw driver.

Legs for holding
Assembly

5. Rotate the lamp cover in anti-clockwise

direction (from your side) till it stops to rotate
and pull it with certain amount of force, and
take out the LED Lamp Cover Assembly.

6. Now insert new LED Lamp Cover assembly

from inside and pull the connector and its
wire toward outside through the hole , at
same time rotate the lamp cover in clockwise
direction, till it stops to rotate.

7. Screw the screw taken out during

disassembly.

9. Assemble the control panel, Drawer and Top

plate.

8. Adjust the Wire through the hooks and

Connect the red connector.

3. Now take the wire of Lamp Cover Assembly

out of the hooks as shown in picture.

(DO NOT forget to connect the connectors of
Control Panel Assembly in PCB Assembly).

CAUTION

•

Power cord must be unplugged before this
work to avoid danger of electric shock.

•

The bulb itself could be very hot when the
dryer just finishes its operation. So before
changing the bulb, be sure that the inside of
the drum is cool down.

With RED 4 , WHITE 6 disconnected from
Controller, check

1) High temperature thermistor ( Wire color :
Blue ) White 6 pin - White 6 pin
resistance ranges table data according to
surrounding temperature.

2) Low temperature thermistor ( Wire color :
Blue ) Red 4 pin - Red 4 pin
resistance ranges table data according
to surrounding temperature.

•When measuring resitance of
Heater thermistor.
It range table data.

•When measuring resitance of
Low temperature thermistor.
It range table data.
