Troubleshooting before calling for service
If abnormality is occurred, confirm the following items in advance before requesting to the customer care center.
Symptom Confirmation Procedures
Air Purifier will not
start.
Air Purifier function
is not working well.
Action of buttons is
not functioning well.
●
Is the power plug unplugged?
●
Whether a power cut occur?
●
Whether the front panel open or not?
●
Is the indoor contamination severe?
●
Are there many particles on the Pre-filter?
●
Are there many particles on the washable HEPA filter?
●
Is the using location too spacey?
●
Is the unit installed at a location where air flows freely?
●
Isn’t there any foreign mater ial like gloves in the hand?
●
Isn’t “locking” lighted at the operation indicator?
●
Plug the power properly.
●
Retrieve working when power cut finish.
●
When the front panel opened, operation cannot be
performed. Close it completely.
●
Ventilate the area to use the product.
Clean the Pre-filter.
Wash with clean water.
(Do not use hot water of 40°C or higher or volatile liquid.)
When drying the filter, avoid fire or direct sunlight and
sufficiently dry it in the shades.
●
Use the product that fits the room size.
●
Avoid using it where it is ventilated well such as entrance,
window etc.)
●
Remove any obstacles.
●
Move and install at a different location.
●
Remove the foreign mater ial such as gloves before the use.
●
Release the locking setup by pressing the Lighting Button
and Off timer Button for about 3 seconds simultaneously.

Troubleshooting before calling for service
Problem Possible cause Solutions
Air outlet has an
abnormal odor
Sensor indicator
has problem.
●
Are you using the product where there is smoke or odor?
●
Are you using the product where there is a food smell?
●
Did you completely dry the washable HEPA filter?
●
Dust sensor keeps high level always.
●
Odor sensor level goes up?
●
Aren't the numerical values of the dust sensor, odor
sensor and cleanness level continuously moving from
side to side?
●
The air cleaning function can deteriorate in locations where
there is a lot of smoke or odor. Ventilate the space and then
use the air purifier.
●
For the food smell, it can be penetrated to the filter,
therefore ventilate the space and then use the air purifier.
●
If you use the washable filter without completely drying it, it
can generate a weird smell. Therefore dry the filter
completely before using it again.
●
Clean the dust sensor or the filter. Due to the vapor particles
generated during the cooking or boiling, the numerical value
of the dust sensor can be raised.
●
LG air purifier is designed to detect polluted air, therefore
odor sensor may not react to food odors. But deodorization
filter will remove odor.
●
It is the Start-up function which prepares the unit for
operation. During this two minutes period, the display will
fluctuate to indicate that the unit is sensing the air quality in
ther room.
