E39 Fault is thermister, Mitsubishi way of saying im not going to start because there is something wrong. Generlly it is compressor fault or short of gas. Im guessing if you turned the power out. Waited twenty seconds, turn it back on. Now if you go to the outdoor part. Wait exactly 3 mins. If you hear the compressor try to start and fail then it would more then likely be your compressor if you dont hear anything and the unit faults out it will either be a board or short of gas.
Either way If the unit is under five years old get a warrenty agent out to look at it.
Sorry I couldnt tell you for sure but MHI are very vague when it comes to fault codes

Hi there. Either your system has a leak (most probable) or the evaporator is icing up caused by a plugged air filter.

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.

continuous flash is frost prevention ...clean the filter & switch fan to high
flashes once every 2 sec could be room air sensor contact loose/short...call dealer
flashes 2x every 2 sec is indoor coil sensor contact loose/short...call dealer
flashes 3x / 2sec sensor contact problem, or compressor overload protection trip or gas leak...call dealer
