I need your advice on how to fix a LG portable air conditioner.
LG may make some of the top rated refrigerators and appliances according to Consumer Reports, but their air conditioners are known for being noisy and problem prone.
That doesn’t help me solve my problem.
If you have one of the LG air conditioners with a remote control, remember that the problem may be the remote, not the AC.
This isn’t going to be solved by changing batteries in the remote and making sure someone else didn’t sit on it and break it.
Some of the LG air conditioners have problems with the heat exhaust tube not directing enough air out and away from the unit, so it shuts down from overheating.
I could try to solve that by moving the tube or insulating it.
At a minimum, you have to make sure the exhaust absolutely blows air outside and not circulates it around the unit.
And I thought it was bad when air conditioners froze up because they didn’t have enough air flow because the curtains were draped around them or the filter was clogged.
LG’s window air conditioners have problems with leakage, too.
The first thing to check there is that the drain pan isn’t clogged and the drain tube isn’t full of grime.
The LG AC manual says the window ACs need to tilt to the outside at least a quarter inch to drain properly.
I’m getting all kinds of errors, though I don’t know if they are caused by hardware problems.
Hit the reset button on the AC to reset it. If the indicator light is green, it thinks everything is fine.
If the indicator light is dark, I know it doesn’t work because it doesn’t have power.
If it is red or orange, the LG air conditioner manual says hit reset on the power plug, then power to try to reset it. And if that doesn’t work, call for tech support.
Most manuals say if you get any error code, call for service.
That doesn’t help much, especially if the AC can get the room cool but takes way longer than you plan in order to do so.
That doesn’t tell me what to do in order to help fix this.
I understand you want to fix it, because getting parts from LG other than through a repair man is almost impossible. The hard part is when it works almost too good.
I can’t imagine how. If it gets things too cold, you turn it up or off.
I’ve seen LG air conditioners spit out cold water or ice.
That could be because of a refrigerant leak causing condensate building up on the coil to freeze, until it sloughs off and comes out the vent with the indoor exhaust.
Getting a coil fixed is hard, as is getting the refrigerant refilled.
However, you do have to pay a repair person to add refrigerant today. The state doesn’t want people endlessly recharging refrigerant that leaks into the atmosphere.
If you get error 32 or 33 for discharge temperatures being too high, that’s probably it.
I didn’t see an error code that high.
Most error codes for LG AC in the twenties are due to currents and connections in the printed circuit board.
At which point, I power cycle the AC and if that doesn’t work, order a new one because that’s cheaper than replacing the control board.
