My LG air conditioner is spitting out water and making a weird noise....i took off the front panel and theres a lot of water in what i guess is a condensation pan....ive tried drying the little bit i can...

Go around the back side and unplug the drain hole! These are designed to drain out the back through a hole in the drain pan. Maybe your unit is tipping forward and not draining like it should. You can use a coat hanger or wire or even a shop vac to remove debris from the drain.

We are getting water leaking inside the window. The unit is slanted enough that is should be draining outside, not in. Is there something that needs to be emptied and how is it accessed? I am not sure what...

The slant is probably correct, but the drain hole in the drain pan, under the rear of the unit is clogged. Finding it can be a challenge at times, as the clog will blend in with the drain hole. Be patient and persistent and you'll find it. A pipe cleaner works well to clear the hole.

Hope this helped you and thanks for choosing FixYa.

My window airconditioner sounds like it has water in it and now its spitting out water in the room?

This can be caused by 2 things:

The drain pan hole is clogged and water is backing up in the pan. Look under the outside part of the AC unit for the drain hole and clear it. It may be hard to find, as the clog will blend in with the hole.

The unit was installed incorrectly and the outside portion (outside the wall) of the unit is not tilted down 1/4" to 1/2". Which allows the water to run to the drain plug.

Correcting either or both of the above 2 things, should solve the problem.

My a/c unit is spitting out water, why?

If it's a window or thru the wall unit. The drain hole in the drain pan under the unit, on the outside may be clogged. Also, if the unit is not tilted down 1/4" to 1/2" on the outside, it will not drain as it should. Look carefully for the condensation pan's drain hole, as it may be hard to find, due to the clog.

Water is leaking out the front of the unit

Water is a normal byproduct of the refrigeration process, Just like a glass of icewater has condensation on the outside of the glass.

The unit is designed to run the water outside. Check the slant of the unit, if it slants inside water will not exit outside..needs slight downward tip towards the outside.

Also check that the drain system is not plugged.

My ac is spitting out water in the front and making a loud noise

Your noise is probably your fan hitting water. First try to tilt the ac to slant to the outside. If this is done water should drain to the outside if not your drain hole is blocked from the front to the back you can see this if you remove the unit and look at the front coil housing you will see a very small weep hole clean it out and use a water hose to clean the front coil and the back coil. good luck

My window air conditioner keeps spitting water out the front

check for clogged drain in back of the unit and make sure the unit is level or slightly slanted toward outside.
May also be caused by debris clogged in evaporator coil.

Condensation buildup

Make sure the unit tilts towards the outside. If it's installed level or tilted toward front it will not drain properly.

How do you clean the drain port on a LG 24000 air conditioner window unit

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!
