The ice maker, located in the door, fails to make ice. The area is cold (certainly cold enough to freeze) and the 'fingers' that move the ice through the tray work. LG customer service had me press and hold the ice size selector button until the mechanical part of the system rotated through a complete cycle. There was no sound of water flowing although I am able to get water from the door dispenser (so water to the entire refrigerator is available). Also there was no motion to the ice-bucket-full detector rod but I don't recall that it ever moved. How does the fridge know that the ice bucket is full? I suspect that the valve controlling water flow into the ice maker tray is bad and that otherwise, things are all playing okay. No proof of this though. Any suggestions?
ICE MAKER WILL NOT MAKE ICE. HAVE REPLACEDTHE FILTER BUT THAT HAS BEEN OUT FOR A WHILE. BUTTON ON INSIDE OF FREEZER (ON/OFF) FLASHES.

Re: Inoperative Ice Maker
FROM WHAT YOU SAYING LG HAS MADE YOU DO A SELF TEST ON THE ICE MAKER AND ITS WORKING FINE.YOU NEED TO CHECK THAT YOUR SECOND WATER VALVE AT THE BACK BOTTOM RIGHT CORNER IS WORKING OK THAT MIGHT BE YOUR PROBLEM.GOODLUCK/ MOHAMED

Suspect that the rubber boot that runs all around the edge of your freezer door is deformed, allowing warm air to seep into your freezer. You will see where your temp sensor is located by clicking into the site of a parts supplier like ShopJimmy.com and pulling up their photo of the guts of your unit.
If the icemaker is loaded with ice or certain areas of the freezer are perhaps overloaded redirecting cold air toward the water output it can freeze. Also if the ICE shoot has ice cubes obscuring it's closure that area gets cold enough to freeze the water. Check after dispensing ice that the round flap is closed.
I open the freezer door and place three regular sized bed pillows placed into white trash bags into the opening being sure to DEPRESS the light latch with one of the pillow placements so it won't constantly sound a door ajar warning.
I then close the door as much as the pillows will allow and place a chair in front to keep the pillows in place for about 25 minutes. Usually this will do it and the water will begin to flow . I draw off enough to run it completely through the entire line . Sometimes a small piece of ice will come out. I had tried hair dryers and all manner of things and just gave this a shot one day and it works when it freezes for whatever reason it will use.
Check to see that the evaporator is not covered with layer of ice. The latter serves as an insulator and prevents freezer temps from going down to about zero degrees. If the defrost heater/timer is defective that will certainly be a cause. Since the freezer air is not cold enough to freeze, then the refrigerator temps are also high. Using a digital thermometer will confirm this.
Leaking door gaskets can also be responsible for higher internal temps
This unit senses the "freeze plate" temperature to decide when to go into "harvest". Either the the temperature sensor (most likely called an evaporator thermsitor) is lying to the control or the plate is not getting cold enough due to a sealed system issue (usually a bad hot gas valve). If you carefully loosen the front grill (staying clear of the wires going to/from the ON/OFF/CLEAN switch) you can see the hot gas valve near the center in the bottom of the mechanical area. If the copper tube coming out of the bottom of the valve is cold during the freezing cycle...it is bad. If not, I would try the thermistor first. If you do not feel comfortable doing this, you should contact a servicer to diagnose the unit for you. Good-Luck.
IT DOESNT MEAN YOU GETTIN WATER IN THE WATER DISPENSER THAT THE VALVE IS OK.MOST FRIDGES ARE FITTED WITH TWO VALVES.CHECK THAT THE ICE MAKER VALVE IS WORKING IF THATS OK YOU MIGHT HAVE A PROBLEM INTERNAL ON THE ICE MAKER BEST YOU GET A TECHNICIAN TO CHECK THAT.GOOD LUCK.MOHAMED
The icemaker stops working because excessive water gets into the control box(where circuit board is housed) through the shaft hole of "finger" and freezes the wheels to turn the "ice-bucket-full detector rod". This stops to send the signal to open water valve.
To fix, remove the icemaker from the wall (need remove two screws - make sure power switch is OFF) and carefully separate the snap-on cable (retangular shape) and a ground cable on the bottom side of the icemaker. (Now you can remove the icemaker out of the refrigerator).
You can open the contol box (need unscrew one and carefully prop it open using a screw driver or a knife. You can unplug color corded snap-on cables for easiness to work (very simple).
You will see ice formed around the plastic gear wheel controlling the "ice-bucket-full detector rod". Remove all ice and dry all the parts in the box and put them back. Make sure all the cable are back to the matching color receptable(only fits in the right place). Connect the cable(rectangular shape) and connect the ground cable. Mount the incemaker on the wall using two screws you removed at first.
Turn the power ON and reset the system by press down the ice cube size selector until the "fingers" make a full cycle. You will see the metal rod moves up and down as system resets. During this cycle the water will be filled into the icemaker.
I believe this icemaker has a design flaw but it's very simple to correct the problem you are experiencing. You do not need much electronic or mechanical knowlege to fix this.
