Possible Causes & Solution
The power plug is unplugged from the outlet.
• Plug it into the outlet properly.
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.
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 k (Lock) is turned on on the status display panel.
• Press and hold the Light button for 3 sec. to disable the lock function.
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 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 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.
