Thanks for watching, and let's get started!
Thank you Mechanical Environments was a big help in deciding to tackle my LG. Did get to watch a Moovair brand get cleaned at work, so decided to tackle after a local contractor stood me up for a booked cleaning appointment.
I've been looking everywhere for this video. Thank you!
Thank you so much for this video!
I'm going out to replace a fan wheel on a unit tomorrow and I've never done that before.
Now I'm not going in blind!
Thanks for a good video.
THANK YOU! Finally a pretty clear video on how to take apart these LG units. I'm finding that after a year with regular filter washes the fan blades have a thin layer of "gunk" on them that needs cleaning. Coils look fine, so it's fine particle dust and probably condensate. Yuk.
My unit only seems to have two screws on the left side bracket and even after removing them I couldn't get the part away from the coils. Manufacture change, or did I miss a screw?
I'm curious though if the dust build up gets "knocked off" in the winter when I switch these things to heat mode. We shall see.
One thing to watch for: On these units there is still lethal 240 volts on the three screws and wires on the right bottom of the handler. So yeah, turn off the breaker when servicing. I also covered that screw block with electrical tape just in case.
Thanks!
THANK YOU!! Haven't been searching for this information everywhere.
Thank you, saved me a ton of frustration lol
Glad it helped!
Thank you!
Thank you so much for your video! May be you also know where can I find a templature sensor there? 😅
Where is the thermistor located?

I have internal dripping from below the tray. From black plastic part. What is could be ?
Boy this is a fun one: I've been chasing this on my top floor units (they are closest to the attic, thus dump the most heat) and I have been through a lot:
First, I don't think it's the drain: Drain works and even though the installer put it on the right side of the unit (leaving a small bit of water in the left side by the plug sump) I don't think that is enough to do it. So it's draining.
Second: I don't think it's insulation but make sure the holes to the outside are plugged and insulated. Putting a layer of fiberglass insulation between the bottom of the black part and the white bottom trim may help.
Third: The water is coming from the *fan* itself, which could mean the unit is clearing a lot of water vapor and it gets blown off the coils before it has a chance to drip down to the pan. You can see the water streaks if you look up and into the unit from where the air comes out.
Also I noticed that if I seal the bottom "lip" between the black part and the white trim with electrical tape that water doesn't collect under the unit on the white trim and drip off. So it's coming from the fan area itself (I can also sometimes feel it "spit" a bit of water)
What to do? Not sure. I might try lower fan speeds or higher fan speeds to see if that keeps it from happening. Worst part is it's highly intermittent. Right now I'm going to try running it in jet mode to see if it drips, then switch to dry mode at low fan speeds.
Also I do have three units on the same condenser (multi zone). It's possible that when the condenser runs all the units at full blast the pressure drops low enough that the highest up unit has a lower working pressure, but I would expect it to simply freeze up. That isn't happening. Also the lower floor 2 units are totally dry with no issues.
@@czperiod2576 i see that this comment was pretty recent, but have you found any solutions? i have a similar situation and am dumbfounded. multiple tech have come out and haven't fixed it either.
@@spicybiscotti I have. Two issues seem to happen: 1) If you have a hole in the wall to the outside and it's not packed (especially if near attic) warm air can come in and condense against bottom of unit. Ergo water drops. Also put some insulation under the lip there.
2) If the unit is really in a humid place and runnning at high fan speeds it can blow the water off the evaporator fins and into the output airstream. Now there is a lip between the white trim and the black part of the AC unit. What I think happens is water is spit out by the fan at full speed, runs down the black part, then hits the little crack of the lip and goes *UNDER* the white trim. Then it accumulates there and dumps.
Try either putting electrical tape across that seam, removing the lip, or running the fan at a slower speed (so the water on the coils drips down instead of being blown out) and see if that helps.
@@spicybiscotti I've pretty much figured it out. What happens is when the coils load up with water they drip down into the pan. HOWEVER if the fan is running at full speed it can blow some of the water through the coils before they hit the drain pan. Thus water drops come out the air exhaust and land on the plastic lip. Then they drip down to where the outside (white) plastic is, go through that little crack, and pile up under the unit. Then when it gets full it dumps down the wall.
So not the drain, and not condensation under the unit. Solution is probably to re-design the unit or something, or not to run it at full fan speed when it's seriously humid.
Try it and let me know if this works for you. Works for both of my problematic units located on the top floor of the house where it is the most humid.
