Freezer has. Ice build up. Will not self defrost. Refrigerator not cool enough causes some food to spoil.
For model number LTNS16121V
Hi James,
Thank you for your question. If the fresh food section of your refrigerator is too warm and the freezer section has ice build up, check and see that the door gaskets are sealing correctly and inspect them for any gaps that may allow warm air inside. Warm air can condense on the walls inside and will start to freeze. Overtime this can cause an ice build up. If the gaskets and the door frames they shut onto are dirty, give them a good cleaning with warm soapy water. Dirt and grit on the gaskets or on the frame it shuts onto can prevent the door from sealing properly. Also, if you leave the door open too long warm can get inside. If the fresh food section of the refrigerator is too warm try adjusting the controls in the freezer section to allow more cold air flow into the fresh food section. If this does not help, we recommend checking both the fresh food display control board and the main electronic control board. If they show signs of damage, wear, scorching, or burn marks, they will need to be replaced. We hope this helps!
The part in question on the LG Refrigerator/Freezer unit was a nylon plastic bushing on the lower hinge, part 4620JJ2003A. One day, there was a snapping noise and the hook part of the bushing broke off. The freezer door still closed, but it wasn't as secure and sometimes closing the fridge door could cause the freezer magnetic door seal to break and open a wee bit. (Didn't lose anything, but it came close twice.)
Repair was simple and it's a one-person job: - Remove everything from the freezer door inside shelf. It's okay if you just set it aside because this repair will take less than 10 minutes, only 2-3 minutes have the door completely off. No need to shut off or unplug the fridge either. - I used some possibly unnecessary duct tape at the top of the freezer door on the opening side to keep the door shut while I worked. - There is a gray plastic cosmetic hinge protector at the top right side. Remove the one Phillips-head screw holding it on. I needed a small pry-bar to gently remove the plastic cover so I wouldn't break it. (There is some kind of wired sensor under there, no idea what it's for, so I just took care not to break it either.) - Use a 10mm nut driver or socket wrench to remove the three bolts holding the silver door hinge bracket in place. Lift the bracket up and off. - At this point, you can remove that duct tape (if you used any) and carefully lift the freezer door up and off the lower hinge. - Turn the door over. There will be a small Phillips screw holding the white nylon hinge bushing door-stopper in place. Unscrew that and pull the old door-stopper out, put the new one back in. There is only one way it can go. Replace the screw. - When putting the freezer door back onto the lower hinge, do so with the door partially open, otherwise the hook part will get stuck and stop the door from being put fully onto the lower hinge. Then close the door. Make sure the freezer door is seated all the way down onto the lower hinge bracket. - Reinstall the upper silver door hinge. You may need to lift the door a bit from the opening side to get the nut holes to line up. - Put the plastic cover back on and screw it down.
That's it, you're done. Test the freezer door to see if it seems to "want" to shut itself in that last inch or so of closing the door. The increase in resistance should be noticeable.
