SOURCE: "Cool" mode shuts off
An E1 error is automatically generated after the AC runs for so many hours to remind you to clean the filter. The owners manual says to clean the filter and unplug the unit, then plug unit back in and code will be reset. However, a User review stated that his code was not reset until he followed a fairly simple routine. "Unplug the unit. Hold down the power button and plug back in. Wait to hear a "beep" and then unplug it again. Plug unit in again and it should restart without E1 code."

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!

There are (4) 1000uf @35V capacitors all together on the DM board that need to be replaced some models have 1000uf @ 16V but they are all right beside each other and all rated at 1000ufs the voltages will be stamped on the capacitor along with the uf ratings.

Hi, I have a spare TU-PT700U that may be of use for you to solve your problem without having to replace your system. My Panasonic onyx series monitor was stolen out of my house, but they left behind the TU-PT700U and cable. If interested, respond to my craigslist post..

Check your remote control using your camera or cellphone camera as your eyes. Point the remote control transmitter to your camera and "on", light should emit in your remote control transmitter (means good remote). Reset the unit by disconnecting the power supply for 10 sec. then "on" again and start the unit. If it wont work you need a qualified tech. to solve the problem.Some of your safety device might be defective.

Hello - I understand the unit has previously experienced a power outage, however have you try unplugging the unit or flipping the household breaker off? Wait approximately ten minutes; is there power to the unit? I suggest touching each button individually on keypad, do any lights turn on or does the display change? If any proves to be ineffective, I would recommend contacting a professional to move forward accurately because it can possibly have a defective keypad.
