The key is the ice maker actually being in the freezer and not in the fridge. With this one being in the actual freezer it looks good. 100% stay away from the ones where it's in the fridge. I speak from experience with these types of terrible units. More on reddit.com

I loved my LG! Great design and it worked perfectly every day until it didn’t. This was before COVID but no one would repair it because parts are so expensive and take so long to get. So I replaced it with a Whirlpool but I miss that better designed LG every day! But I can’t replace a fridge every five years. More on reddit.com

The first thing I would check: pull out fridge and remove panel on lower back. It will have air vents and should be easily removed. Have a look, if there is a great deal of dust, take a vacuum and clean it out as best as possible. Likely cause of issue- too much dust can clog the coils and reduce cooling capacity. Second thing, briefly touch the large spherical tank, that is the compressor, if it is hot to the touch it is cooling properly, If it is lukewarm or cold the compressor may have failed. Third thing, there will be a small fan directly next to the compressor whose job it is to remove heat from the system through the vents, if this fan is turning but is making noise it may need a cleaning and a spritz of WD-40, poor fan performance and clogged vents can also lead to poor compressor performance or failure. Fourth thing, If none of those seem the issue, check vents in the back of the freezer, check for airflow or ice buildup, excessive ice buildup can reduce air flow which will compound upon itself. Fifth thing, check the gaskets around the doors to ensure the door to the freezer and fridge are both sealing properly. Last thing, if no ice buildup and airflow okay, maybe a problem with freezers thermostat or defrost timer, or potentially the control board. There are in-depth YouTube videos regarding all of these steps that you can look at for reference if needed. Final note, with a fridge only 3 years old my first guess is the dust buildup on the coils and the compressor fan More on reddit.com

When the freezer defrost ,the melted ice drips into a trough and then goes through a tube underneath the fridge where it is evaporated. If the tube gets stopped up it will cause the water to freeze or drain on bottom because it can’t drain. Find the tube at the back where the ice is and melt the ice and unstop the tube with air pressure etc. More on reddit.com
