The appliance does not operate.
The power plug in unplugged from the outlet.
Plug it into the outlet properly.
There is odor, but the air quality light doesn’t change.
Is the air quality light red or orange?
The color of the overall air quality light is determined by the worst level sensed, whether that is a PM concentration or odor. The PM concentration level may be worse than the odor level.
The odor (gas) sensor is designed to detect harmful gases. Strong food odors may not register as harmful, but the Deodorizing Care filter will minimize them.
The air quality light stays red.
Move the appliance to a different room and see if the color changes.
If the odor level is beyond the capacity of the product to dispel, the light may not change.
Clean the sensor area.
Remove the power plug from the outlet and reconnect it one minute later.
A substance was sprayed near the product.
Do not use sprays near the product.
The buttons on the control panel do not work.
The k (Lock) is turned on on the status display panel.
Press and hold the Sleep Timer button for 3 sec. To disable the lock function.
The PM concentration doesn’t change.
There is a foreign substance on the sensor.
Clean the PM1.0 sensor.
The product is used in an enclosed space.
In an enclosed space without frequent air exchange, the air quality may stay the same.
The PM concentration stays high.
The product is located in an area with frequent airflow from the outside.
In an environment where outside air is supplied continuously, the PM concentration may remain high.
The color of the overall air quality light does not match the PM concentration value.
The overall air quality light may be reflecting the odor level.
The overall air quality is based on both the PM concentration and the odor level, and its color is determined by which is worse.
If the PM concentration is low and the odor level is high, the overall air quality light will reflect the odor level.
The clean booster is not working.
The Booster mode is not selected.
The booster fan speed and booster fan rotation functions work only in the Booster mode.
The PM concentration levels are different between the appliance and the LG ThinQ app.
Make sure you are comparing the levels for the same size particulates.
Make sure that the levels of the PM1.0/PM2.5/PM10 are displayed consistently between the LG ThinQ app and your appliance.
The LG ThinQ app may not update the sensor results as quickly as the appliance display.
