The CH01 era code would indicate a indoor sensor Fault

LG Heating &... | Answered on Oct 28, 2019


Fault Code 05

This fault code indicates a communication error between the indoor and outdoor units; this is usually caused

by wiring errors or condensate pumps connected to the inter-connecting cable.

The communication between the units is a fluctuating DC voltage commonly called a serial signal, it can be

easily lost if the wiring is not done correctly. If there is a communication error fault CH05 will appear within 5
mins of powering up the system.

Not sure if this is what you're looking for, but if it might help... I just posted this on a similar issue (water buildup in the front of the unit and/or a rattling noise when the fan is running - sounds like it's running through water and it's spitting water out of the vent). I'm guessing that it's designed similarly to other LG units...

If the unit has been working fine for a long time and then you suddenly have this issue, the angle you have the unit set at is probably fine, but you probably have a blockage of dirt/mud/sludge/whatever that is keeping it from draining properly. Here's what you have to do...

For safety... turn the unit OFF and UNPLUG IT.
Open the front gate and remove the air filter. Next, remove the entire front gate from the unit (probably at least one screw to remove first - mine was in the middle, just under wher the bottom of the air filter sits). With the gate removed you should have access to locate your blockage problem.

There is a hole that allows the water to drain from the front of the unit (the part that is inside your house) to the back of the unit (the part that hangs outside your house) and eventually out of a drain hole in the rear. Chances are that this hole is clogged. So, when the water fills up in the front drip tray it has no access to drain to the back. Consequently, the water builds up in the fan area which causes the rattling noise and the water being picked up by the fan and blown out of the vent. If left too long, it will overflow the front drip tray and make a mess in your house.

On my unit, the hole was on the far left side (if your are in your house and facing the AC unit) of the drip tray. You can use a piece of coathanger wire, or some other long thin instrument to push the blockage through to the rear. Once this pathway from the front of the unit to the back of the unit is clear, your problem should be solved. You will probably still get the sound and water sputter out of the front for a little while until the water that is in the fan area drains/dries out, but it should return to normal soon.

It is probably best to actually remove the unit from the window and take the cover off of it and really clean it out, but that is obviously a much more involved task. If you have a hose, that's fine and will help. Water won't hurt the unit - just keep it away from the electronics (the controls/display/cord). You should also be carful not to bend any of the tiny metal fins... that's just as bad as (actually worse than) being blocked by dirt/dust. And obviously, allow the unit to dry before you put the cover back on and put it back in your window and plug it in to run it. If you are willing to put in the extra time and effort, you can do a more thorough cleaning job, which would help to prevent the problem from happening again too soon. There's no way to prevent dirt/dust from building up in the unit. Once water/moisture is added to the mix, you're dealing with mud/sludge, which is going to eventually block that small drain path. The only solution is to clean it out once in a while.

I figured this out the hard way. I took the thing out of the window cleaned it (not as thoroughly as I thought) and put it back in and then did it all again. The third time I actually found the hole that was blocked. If it hadn't been such a pain taking it all apart and cleaning it the first two times I would have laughed at myself for missing it.

Good luck! Hope this helps!

The FL error usually means that there is excess water in the drain pan. Look for the drain plug cap at the bottom of the back of the air conditioner. Remove the cap and tilt the air conditioner so that any water in the drain pan will run out. If the room is extremely humid and the air conditioner is set to Cool, this is normal. To reduce the water level issue, set the fan speed to Low. If the air conditioner is in the Dry (dehumidifying) mode, try setting it to Cool. Alternatively, consider using a hose if your unit allows for a continuous drain.

Unplug the air conditioner for at least 10 seconds to reset the unit if the error persists. If the drain pan is dry or the error recurs before more water fills the drain pan after the reset, then the air conditioner needs service.

Please add a comment with the model number of the unit if you need help finding the drain pan cap. I hope this helps.

I just googled it and found an error code ch38 means indoor fan is not running, it's simple... Clean your filters people, it's not blowing enough air. Maybe it actually is the fan motor, it's too funked up now from not changing/ cleaning filter, or the wire came loose, I would put my electrical tester on the fan motor contacts and see if there's voltage during a call for cooling, if there's power to the fan but it does not run, your motor is dead, no amount of refrigerant will fix this so maybe call them back and have them do this
