I bought a house that has a few LG split air cons.
Whenever I want to use them I need to get like 2 meter close to them for the remotes to work which feels too short and annoying. These units are 10 years old and I already changed the batteries for all remote to try if it would solve the issue.
So my question is what could have happened over these 10 years to reduce the range of the remote controls? Is there anything I can do to improve it?
I thought maybe the plastic in front of the IR sensor got opaque? Any change the remotes or the receiver start to loose power over time?
