Try sutting off the power to both units. This may reset the unit. Check out the service manual at LG website www.lgusa.com. Go to their support page and put the model number in. Remove and replace the batteries in the remote. If there is a communication error, the inside unit will display 3 flashes. If all else fails, call LG at 1-800-243-0000. Good Luck!

If the unit displays Error E4
1)Check whether the winding resistance and
operation current of the compressor are normal.
2)Check whether the high and low pressure is normal
when the unit is running.
3)Check (whether the coil pipe sensor is normal)
whether the contact of the inserted on the circuit
board is well, the coil pipe temperature sensor is
fixed, the evaporation of the indoor unit is well,
the key is to check the evaporator temperature
detected by the coil pipe temperature sensor has
reached the cooling or heating temperature.
4)Check whether the surface of the condenser is too
dirty, it should be cleaned when it is too dirty.
5)Check whether the capacitance of the outdoor motor
and the fan is damaged, it should be replaced when
it is damaged.
6)If the above items are normal, the electric control
board should be replaced.
Please do rate the solution if the issue is resolved or post a comment for further assistance.

Check there will be red icon when power is on,before switch on by emote. If no red light, there is no power goes into indoor unit. Check. If red light is there and no response with remote, communication error between remote and PCB in indoor. Try with other same type remote. If yes, replace battery or replace your remote. If no, receiving sensor in PCB problem. Repair or replace it.
