Problem
Possible Causes
Corrective Action
There is noise or
vibration.
A clicking sound can be heard
when the unit starts or stops due
to movement of the reversing
valve.
Creaking sound: The plastic parts
of the indoor unit creak when
they shrink or expand due to
sudden temperature changes.
Flowing or Blowing sound: This
is the flow of refrigerant through
the air conditioner.
•
These are normal symptoms. The noise
will stop.
The indoor unit gives
off an odor.
Odors (such as cigarette smoke)
may be absorbed into the indoor
unit and discharged with airflow.
•
If the smell does not disappear, you need
to wash the filter. If this does not work,
contact the service center to clean your
heat exchanger.
The air conditioner
does not emit warm air.
When Heating Mode starts, the
vane is almost closed, and no air
comes out, even though the
outdoor unit is operating.
•
This symptom is normal. Please wait until
the unit has generated enough warm air to
blow through the indoor unit.
The outdoor unit is in Defrosting
Mode.
•
In Heating Mode, ice/frost is built up on
the coils when the outside temperature
falls. This function removes a layer of frost
on the coil, and it should finish in
approximately 15 minutes.
Outside temperature is too low.
•
The heating effect may not be sufficient.
Your home appliance
and smartphone is not
connected to the Wi-Fi
network.
The password for the Wi-Fi that
you are trying to connect to is
incorrect.
•
Find the Wi-Fi network connected to your
smartphone and remove it, then register
your appliance on LG ThinQ.
Mobile data for your smartphone
is turned on.
•
Turn off the
Mobile data
of your
smartphone and register the appliance
using the Wi-Fi network.
The wireless network name (SSID)
is set incorrectly.
•
The wireless network name (SSID) should
be a combination of English letters and
numbers. (Do not use special characters.)
The router frequency is not 2.4
GHz.
•
Only a 2.4 GHz router frequency is
supported. Set the wireless router to 2.4
GHz and connect the appliance to the
wireless router. To check the router
frequency, check with your Internet service
provider or the router manufacturer.
The distance between the
appliance and the router is too
far.
•
If the distance between the appliance and
the router is too far, the signal may be
weak and the connection may not be
configured correctly. Move the location of
the router so that it is closer to the
appliance.
NOTE
•
Some functions may not be supported, depending on the model.
