20 Most Recent LG Electronic Window Air Conditioner - Page 6 Questions & Answers

If you are not getting cold air then your evaporator is not working. First thing to look at is listen if you hear your compressor running. No compression means no cooling on evaporator. If the compressor is running check the operating current and if not running check to see if the thermostat setting is on the coldest setting

All LG room air conditioners should be able to be operated without using the remote, by just using the controls on the unit. Replacement remotes are available from an LG service provider.

reset your timer on the remote .then you would be ok

Check the theremostat probe to see if it may be too close to the evaporator fins behind filter if touching fins it will feel evaporator being cold before room air and send model number too, Sea Breeze

MAKE SURE ENERGY SAVER IS ON SO FAN SHUTS OFF WITH COMPRESSOR. AND MAKE SURE THERMOSTAT IS SET TO COLDEST SETTING FIRST. IF THAT DOSENT DO IT YOU MAY HAVE ANOTHER PROBLEM.

well if ever thing is working ok after fill freon. start with cleaning both coils dirt can stop air flow .

Just guessing, here. The reset is actually a "Ground Fault Interrupter" called a GFI. It's there to cut of power in case of a dangerous electrical condition--which you probably don't have.

Did you unplug the unit? If not do so, let the GFI cool for several minutes, and try to reset again. They're pretty hard to push in, maybe use a fingernail, you must hear a click or it's not reset.

Is there water in the outdoor unit, or is it filled with snow? This is the most likely cause of an actual GFI fault.

If the GFI itself has failed (unlikely), you could replace the entire power cord. You should then maintain safety by installing a GFI circuit breaker on that circuit, or you'll be in violation of codes that might affect your homeowners insurance.

There could actually be a problem with the unit. This would be that an electrical wire has come loose and is contacting the metal chassis, creating a shock hazard. Unlikely but possible.

If the receptacal you're plugging into is old and worn it might the problem. Worn receptacles might actually have tiny electrical arcs inside, which can trip a GFI. At a couple of bucks (DIY) it's worth a shot.

If there's actually an electrical fault in the unit it can be found and repaired, but the cost of repair could very well be more than it's worth. Warranty?

This alarm state is a CH 06 alarm.
Indication for the Indoor unit pipe temperature sensor (thermister) not plugged in or out of calibration.

This alarm will also occur when the unit gas charge is to low and the indoor unit temperature reached a temperature of -5°C for longer that 30 sec. It will switch the machine off.

Check/clean intake air filter and condenser fins,as well as be sure condensation drain is clear as well. Sometimes if not the right angle, moisture remains inside unit rather than draining outside, or wherever your drain is, make sure it's clear and draining well.

Call an LG Support Representative at (800) 243-0000.

Hope this helps,

You can try to clean the filter and also the outdoor side condenser fins which may have dust and dirt. The indoor filter simply slides out of the front panel. The outdoor side can be sprayed (while unit is off) with a hose.

I have a similar situation with 66 a/c units in my motel. The problem is the drain valve in the back of the unit (near the compressor) does not function properly. It is supposed to open when the water temp (laying in the bottom of the unit) gets to 50 degrees cusing the drain valve to open and let the water out. The problem is the water never reaches 50 degrees when the outside temperature is in the 80's. So the water sets in the units. The fan sprays the water over the fan motor, heating element and inside the chasis causing it to rust from the inside out. I have notified LG and they are investigating it...... Amana has the same problems with their units which use the same drain valve and they have removed the drain valve in several motels in the area.
I would suggest removing the drain valve or wedging something under the little round plate so the the unit drains. Also make sure your A/C is tilted properly so the water runs to the back of the unit and drains.

there is a drain on the pan under the cooling coil - your "blades" if you are looking in from the front cover - the opening could be stopped up going to the back of the unit - you will have to pull it out of shell to see drain line

please check the temperature sensor this will make the compressor for running and stopping and also check the compressor if its in warranty period please call the service technician to check these and replace if necessary.

the fact that it is not draining could be the problem with it freezing up. you might have to pull it out of the window, pop the cover off and clean the drain pan so it will drain properly. also make sure the unit is level . if it still freezes up once draining properly it is probably low on charge.

Unplug it and leave it unplugged for a few minutes, plug it in and try again
