I would first check the condensate drain pipe. This can be done by blowing back into the drainpipe from outside. Not to worry it is not dirty or dangerous. Also make sure that your air filters are clean.

You need to bypass the on/off switch by jumping it, thereby taking the switch out of the circuit. If it works you have a bad switch. If it doesn't you have a power to the switch problem. Do you have a multimeter and a wiring diagram for this unit?
It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.
You can call lg and they can tell you the fault code they are also listed on the back of the control panels where the wiring is in the outdoor unit on most units cut the power off before going into these panels
Here is the troubleshooting guide for your unit. Hope this helps.
TROUBLE SHOOTING GUIDE TROUBLESHOOTING Symptom Remedy 1. Remote does not turn on system - Check and replace remote batteries if the display fades while any button is activated or no display is present. - Point remote towards IR receiver during transmission. 2. System does not turn on, no green LED & no beep - Check wiring. (see "installation instruction") - Check modular cable to receiver. - Check diagnostic LED status in the upper unit control box. 3. System does not turn on even when receiver green LED is on. - Low or over voltage condition, check diagnostic LED status in the upper unit control box.
4. Fan runs but no cold air. - Evaporator temperature sensor reaches low limit, defrost mode. - Check diagnostic LED status in the upper unit control box. 5. System runs continuously in the cool mode - Remote was set for "I feel" mode and is left in a heated environment (sun etc.) 6. System runs continuously in the heat mode - Remote was set for "I feel" mode and is left in a cool environment
1. Diagnostic LED (green) (Note: Located on the control board in the upper unit control box.) a) The LED is on when the 12VDC is adequate and communications are present. b) The LED is flashing fast and steady when in the freeze mode. Evaporator has frozen and the freeze proctection switch is engaged. c) The LED is flashing slow and steady when the delay on break timer is activated. d) The LED is flashing 1 cycle on and off for one second with high or low 12VDC. Check the incoming 12VDC power for OK. e) The LED is flashing 2 cycles on and off for one second with a communication problem. Problem with the control board in the unit and the remote.
