Most probably if the remote works on the other units then the receiver on your problem unit is busted. You have to call an authorized service repair shopr to replace the board.

Generally, they are operated by a remote control (similar to a television), although some units do have a wired wall control option as well. The indoor and outdoor unit has sensors that measure temperature (to control the operation of the mini-split) and (once the remote is set) the sensors control the system until it reaches the set point set on the remote.
see the led bulb of the remote control by using a camera then switch on the remote if it blink the remote is good but if not its bad. dont forget to put an battery on it. then test the ac unit manually, if the unit start replaced your remote control.
Sound like a defective receiver board. Have this checked. Also check to see that your remote transmits. Hold the top part of the remote to your phone or digital camera lens. press a button and a light should appear on the screen of your phone or digital camera screen.

check your remote control using your camera or cellphone camera as your eyes. Point the remote control transmitter to your camera and "on", light should emit in your remote control transmitter (means good remote). Check for reset or rst button in your remote control and push it to reset and test it in your unit. If wont work means either the receiver board or mean board is defective.You need a qualified tech. for this problem. For the mean time you can use manual button to operate the unit.
Check your remote control by using your camera or cellphone camera as your eyes. Point the remote control to the camera and "on" the remote control. If no lights emits in the remote control means that your remote control is defective If lights emits then the remote control is ok. Try also to locate the reset or rst button on the remote control if available and reset it, then try. If it wont work may be the receiver board in the unit is defective.
there is a lot of reason why your LG split unit would not work by remote control.
first likely trouble is the remote itself. it could have drop from a height and broke the remote, or corrosion has set inside the remote if you left an old battery for a long time and it could have broken it.
secondly which is not more likely to happen is the remote receiver in your unit got broke that is why it can not communicate with your remote controller. it could happen if someone has serviced your evaporator and could have disconnected wires to the receiver , or wires were just left not connected.
you can test the remote if you have an identical unit which is working with a working remote. use the working remote to your unit then you can decide.
i hope i was able to help.
