Question about LG LWHD1009R Air Conditioner

Open Question

My recently May 3rd, 2010 purchased LG LWHD1009R Air Conditioner runs very well and cools great. Noise is not bad at lowest fan setting which is all I need really. My only complaint is the rattle buzzing type noise coming from the Air Intake or the Inlet Grille in the front of the AC. When you lower it the noise and rattle stop and the AC keeps running great. When I put it back up and connect both sides the rattle returns. I notice that if I put it back up but only connect one of the 2 prongs on the inlet grille the rattling does not exist. I I connect both of the 2 the rattle begins with a buzzing sound with it. How could I fix this?

SOURCE: Loud Rattle and Leaking

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!

SOURCE: I have an LG AC and the lowest temperature setting is 60 degrees

Lowering the temperature setting doesn't change the temperature of the air coming out of the unit it just lets it run until the room temperature gets colder. Check the temp of the air coming out of the unit. If it isn't as cold as it used to be the charge could be low. First though you should make sure the filters are clean and the coils.You should also check the actual room temp. It's also possible the unit doesn't have enough capacity to keep up with the cooling load of the room.

SOURCE: Hi. I recently installed 1.5 T, 3 * Split AC, LG.

Hello

Sounds like the compressor is shuting down on high heat.There could be a couple reasons for this.
1 Check that proper voltage is being supplied to compressor.
2 Freon level may be low.This would be a service call.
3 Bad or intermitent connection at thermostat.
4 Main contacts to compressor sticking,usually burnt or pitted.

SOURCE: My LG air conditioner unit

Hello, most likely the fan came off the shaft or the fan is loose and hitting the housing or the bearings are wearing out. In order to check you would have to remove the ac from the window and take off the cover, if the fan is secure and if you spin it by hand and makes noisebthan the bearings are wearing out and the motor will have to be replaced soon. If the fan is loose than it either has to be retightened or is the fan hub is cracked than the fan blade must be replaced.

Most window air conditioners run the fan all the time but cycle on and off the compressor that makes it blow cold air, I knew a AC that was a small Hunter Bay brand (which I think is LG) that shut fan off also when it reached the right temperature.

Hard to test them in winter, you may not have it warm enough in the room for it to start making cold air, generally speaking that could be the problem.

We have a LG model lwhd1009r. We cleaned out the unit and the coils are still freezing up and not cooling. We turn the the fan on and it thaws right away, but as soon as you turn on the compressor it...


there are 2 possiblities on this . 1 the indoor fan is running to slow you need to run it at hihg . or the unit is low on charge. Try running it on high fan and see if that does not solve the problem also close any vnets on the unit that say fresh air or outside air. when its really humide you don't need to bring in more. Let me know hope this help ... Jon

GE AGL05 Air Conditioner Problem


Try the fan only setting. If it still buzzes, that would mean a fan issue. An object obstructing the fan, or a bad fan motor. If it runs on fan only, but buzzes on a cooling setting, that would indicate a compressor issue.
