We have had a similar problm and it has ended up being the energy saving light bulbs in the house, when we turn on the light switch on the energy saving bulbs they can send out a similar frequency turning on the ac unit, if you do not have the light bulbs its more than likely a fault in the pc or you have programmed the on/off timer to start the ac? hope this helps

Ok. So first things first. LG have a reputation with all their products. THEY ARE ALL BAD! If you remember GoldStar, they are now LG. GoldStar had horrible products. Now this is what LG has. The fact that the filters are cleaned and the units are serviced is an abosulte plus and will provide the units with extra longevity. Now are these drains are they used for water drainage. If so the upstairs units shouldn't need them unless there is some sort of rise in the drain pipe.
Now to the noise. It seems like there is something which is causing the fan to make a noise. It could be loose bearing or a piece of the fan which has broken away causing it to hit the inside of the unit. Since it is on both units, it would be a generic problem with this series and unfortunately is what you are stuck with now.
To combat this problem, I would: ring LG and the company who installed them and demand that they be repaired and have a warranty on the repairs. Just a heads up, LG are really bad to contact should you have a complaint, so keep persisting that they be repaired free of charge since that they are still under warranty.
If you are not happy with LG or your installers response, I would remove the units and have another brand put in. I recommend Mitsubishi Heavy Industries and Panasonic. Both units are whisper quiet. In fact they are quieter that the LG.
Oh and that only reason why LG boast about their "whisper quiet-ness" is because that is probably the only good going for them - and thats' not even right!
I hope that I have helped you in some way. Good Luck!

SOURCE: LG split (3 indoor) LMU360CE
The LED #2 is only flashing while in disconnection or short in Thermistor (3 sec off / 0.5 sec on). If you want to change it, note: this is not an easy job to do! You will need to remove the top panel, then remove the control paneland then the front panel to gain access to the thermistor. The part isnot available to the public and requires an authorized service techfrom LG to take care of this problem. You will need a special tool toremove the front door seal spring clamp.
But you can call customer service @ 800 243 000 and see if theycan transfer you over to parts. Just give them the model and serial #and see if they would be willing to sell you the thermistor part. Youwill also need the door seal spring clamp removal tool to make the jobeasier.

Please specify the make and model of your unit.
If this is a LG inverter model.
The six flashes of the indoor unit light indicates a CH 06 alarm.
This alarm state indicates that the indoor unit pipe temperature sensor has measured a temperature out of range or the unit is protecting itself from this low temp state. Indoor unit coil temperature to low. Should it have reached a temperature of -5°C for longer that 30sec it will switch the machine off.
It could indicate that the unit refrigerant charge is too low or the sensor has gone out of calibration.
It should measure 5kΩ @ 25°C

First check your circuit breaker or fuse that supplies power to the outside unit. It's probably separate from the inside unit. Then try to turn unit on. If the fan and compressor just make a humming sound then turn it off and check the capacitor if you have a multimeter. You can also look at it and see if the top looks expanded. That's a good sign its bad, but not all bad one's look expanded. Tomorrow I will have access to an LG service manual and can let you know what the code means. Sorry I can't get it sooner. Let me know what you find.
