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!

hi,
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.


Thank you for using fixya have a nice day:-)

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.

What does the code on the screen mean flashes between ch and 05 ?


CH 5 on these units indicates a communications error between the indoor and outdoor units. Generally, it will require a replacement outdoor board assembly to repair it. Lookup LG parts on the internet or ring them for your nearest Agent or parts. 800 243-0000

I want to know that how mini split system automatic work? there is any thermostate or any other device?


Generally, they are operated by a remote control (similar to a television), although some units do have a wired wall control option as well. The indoor and outdoor unit has sensors that measure temperature (to control the operation of the mini-split) and (once the remote is set) the sensors control the system until it reaches the set point set on the remote.

Hello, I purchase an LG dual split minisplit air conditioner. It worked all summer long but now both wall units display a "CH 46" error and do not turn on. Any idea what the problem is and how...


A CH46 error indicates the low side sensor or suction line sensor is defective and not within acceptable parameters. It may be loose or off or simply bad.

LG Ductless Mini Split System LAN125hv: Heat pump doesn't run.


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.
