Question about Samsung Heating & Cooling
I have had similar problems with Samsung. Apparently, the indoor board fits a lot of different models and each has to be "programmed" in to suit your model. Not sure what was wrong with your machine before but it has been known for these units to have a faulty outdoor fan motor which causes the outdoor board to fail as well. When this happens, the indoor unit will usually work fine for about a minute or 2 and then shut down, with lights flashing. The outdoor wont start at all. If these were the symptoms, I would suggest putting your old indoor PCB back and then getting a new outdoor fan motor and outdoor PCB.

I'm guessing its a window type A/C. First Remove the fron cover of the A/C, its a snap on so you just need to gently. Next is pull out the inner assmbly, the drain pan usually has a handle curve you can pull, be careful not to drop the AC. from there you can clean the unit and declogg the drain by hosing it down.
I hope this helps

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.
