Solution
If the same product is
registered under a new
account, the previous
account and information
will be deleted. The new
account supersedes the
old account information.
The membership sign
up is managed by LG
Electronics enterprise
wide. If you have signed
up previously, log in with
your account information
and then register the
product. When attempting
to sign up with the same
ID, a message stating
that the ID already exists
will pop up.
The air conditioner
control is given to the
smartphone which is
logged in first. The A/C
cannot be controlled
by multiple users at the
same time. Once the
user logs out, the A/C
becomes available for
other users.
Check the wireless
connection status of the
smartphone.
The app may shut down
once in a while due to
memory limitations of the
smartphone. Close any
unnecessary apps that
may be running in the
background before using
the LG Smart AC app to
control the indoor unit.
