Possibly a clogged piece of ice from water leakage preventing the dispensing of ice. If you haven't tried taking the ice bucket out and rinsing it under hot water to get all the frozen ice out, you should.
Lowering the water pressure to the fridge by turning the knob on the connection at the wall should help prevent the excess water and clogging going forward. There is a very small change between almost off and just on, where the water will still dispense from the front of the fridge but you can tell that the pressure is less, that should give the desired results. It may take some trial and error by testing the water flow from the door while adjusting the valve at the wall.
The water pressure adjustment may help with the flooding problem under the meat/cheese drawer as well, but most likely you have a clogged drain too because it's a very common issue with these fridges. There should be a panel on the bottom back of the fridge with 3 or 4 Phillips head screws that opens access to the drain tubes which are just about in the horizontal center. The drain tubes are little white plastic tubes with flexible bulges (they look like really oversized whitish/clear bendy straws). They are about 5 inches long each and you will probably see a bunch of gunk at the bottom where they enter the plastic evaporation tray. There is a rubber grommet with a flap on the end of them that needs to be cleaned out, and there may even be some ice formed in the tube that needs to be cleaned out. This will take a bit of time and patience while crouching or on your knees, so be ready for that and have towels ready for excess water. I found a turkey baster and a glass of warm water to be very helpful as well.
Your water filter, if you have one installed, is located in the light housing of the top shelf. It is easiest to take your food off of the top shelf and remove the shelf to get easy access to it. I normally place a towel under it to catch any drips. If you do not see the canister hanging down then the bypass is likely installed. This is not a filter and can be used if no filter is desired. The "change filter" light will go off after a certain amount of time, or usage regardless if the filter,or bypass is installed.
Remove the door and reverse the brackets, mount it to the opposite side. Be careful when removing and mounting as it's not extremely heavy but awkward and you can damage the threads in the body of the unit itself, just be careful and get a family member, friend or neighbor to help. I just done this a few weeks ago, a bit of competent help is best!
Let me know if this is helpful by clicking "Helpful", feel free to leave very brief review or follow me, I deal with automotive/mechanical/technical and other subjects relevant to daily life. Thanks and have a great day!
We just did ours a few days ago. LG-GR419 could be similar to yours. Freezer part.
We found the bottom drawer stuck with ice - frozen water dripping out from the drain. So, took three screws out. Due to the drain being frozen (could be a result of someone leaving the freezer door open at some point and then just closing it after some melt...the back panel will come off with a tug - after the ice behind it melted. We used a hair dryer to do this - sparingly. Can't afford to melt any plastic.
Then once tugged off, we saw a layer of ice in the tray and defrost that with the hair dryer - until everything is clear. At the back of the fridge, we took off the panel - cleaned the dust clogging the slits - my Goodness, no wonder the fridge was working so hard! Chockablock! Anyway, traced the drain hole to a tube. But at that point, not sure why the drained water doesn't go through the tube - perhaps it is not meant to...maybe it is a slow drip and the fan at the back evaporates the water collected - so that was it. So far, it is back to normal. We also found it quieter.
If you have an icemaker and water dispensor that is connected to the house water line, you need to locate that line and shut if off at the connection. The water might be from the defrost cycle that the unit uses though. If it is not appearing all the time, appears to be dirty or a fixed size puddle, the issue is with the defroster and not the water dispensor.
