Check or replace the water filter

I had the same problem and replacing the filter solved the problem for me.

SOURCE: water dispenser on front of refrigerator door does not dispense water. Ice Cube maker continues to make ice cubes. Defrosting doesn't fix problem.

Water dispensing solenoid is bad. You need to replace the solenoid valve. This typically is independent of the ice maker.

I was able to order the ice tray myself and install it in the fridge - it's not hard. I ordered from one of the parts sellers linked to at the LG website, not those listed in other posts here.

Here's how to replace the tray:

You need to remove the tray dumping mechanism to do this.

1. Remove the ice bin, set it aside (don't forget to deal with the ice melt).
2. Turn the ice maker off (LG says to unplug the fridge, I didn't).
3. On the left hand side of the ice tray dumping mechanism there is a screw helping to keep the entire thing suspended from the ceiling of the freezer. Remove that screw- don't worry, the mechanism will stay put for now.
4. The dumping mechanism can now slide forward- note that you can't completely remove it from the freezer yet, but slide it forward and it will no longer be suspended from the ceiling. Don't let it drop or hang.
5. You need to disconnect its power supply now. On the left hand side you should see a small bundle of wires coming from the back of the freezer to the dumping mechanism. It connects to the dumping mechanism's set of wires with a pair of white plugs. Pull these plugs apart. You may need to pry the catch on these plugs apart while you pull.
6. Now you can take the dumping mechanism out of the freezer (and close your freezer).
7. To remove the ice tray you need to slide the housing that contains the rotating motor out of the housing. This is on the right side of the mechanism. If you have trouble identifying it look at the underside of the entire thing and you'll see a small "test" button. That button is on the motor.
8. To remove the motor you'll see two catches on the right side- you'll need to pull these catches out without breaking anything. You'll be able to slide the motor down and out when you get it right.
9. Sliding the motor out lets you get the old ice tray out now. There is probably a set of white wires routed through a little catch on the old ice tray that you'll need to free.
10. Put the new ice tray back on the motor. You'll need to get the left side secured at the same time you get the motor housing in its catches of the dumping mechanism.
11. Reroute those white wires back on the new ice tray.
12. Reconnect the electric wires to the housing.
    
13. Slide the entire dumping housing back onto the ceiling of the freezer and screw in on the left side.

The water line is freezing in the door due to deteriorated insulation. The only fix I have found to work on my fridge was to defrost the inside door with a blow dryer. Then place a weedeater replacement line (the orange 10" or so size you find at Lowes' or Home Depot) up through the dispenser nozzle, If the line only travels about 3-4 inches up the nozzle, then ice is still in the tube. Blow dry it until you are able to get water to dispense. After the tube is ice-free, place the weedeater line up throuth the dispenser nozzle leaving about 1/8" sticking out. The dispenser will still work with the line stuck in it. The dispenser will probably freeze again in about 8 hours, But all you need to do each time this happens is to pull the weedeater line out, dispense the water to unclog the ice, and place the weedeater line back in the nozzle. I have been using this method for about a week now and it works great. My GE Side-by-side is also 4 years old and this seems to be a problem with all of them. There is a part you can order to fix the problem, but I have heard it may not work.
