Inoperative Ice Maker

Our water has been working fine.

Our problem is that the feeler arm gets stuck in "up" position, therefore, it doesn't make ice even when the bucket is empty. Someone had suggested the arm may be freezing in place. That seemed to be an accurate diagnosis since every time we turned the ice machine off and gave it time to defrost, the arm would lower to the down position. Subsequently, when we turned the ice machine on, it would freeze in the up position. As I looked closely, I could see some water seeping through the box that houses the feeler arm. I could see where the water could be freezing the arm up.

I didn't have the time to deal with the issue for awhile--over a month (not too big of an issue during the winter months when we're not needing that many ice cubes!). Then just a couple of days ago, I decided to check into the problem again. The box that houses the feeler arm seemed to have dried out a bit since I didn't see any water. Just to be sure, I used a hot hair dryer on it for a few minutes (directing it into the cracks) to dry it out. So far so good! The feeler arm stayed down when we started up the machine and has made a full bucket of ice without freezing up. I hope it lasts.

This may not address the root of the problem: water getting into the feeler arm box.

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.

Below is what worked for me:

I have the Kenmore Elite Trio French door refrigerator - this is made by LG Electronics

Based on Harvy's and others' comments, here is what I did:

1) Turn off the ice maker for 10 or more hours and remove the ice bucket - this is to give the ice maker time to thaw out if there is any ice build up. (I even used a hair dryer on the feeler arm after the ice maker was off over night)

2) DO NOT TOUCH THE FEELER (ice measuring) ARM!! - When the ice maker is making ice the Feeler arm will be UP - yes, UP!! UP means MAKE ICE.

(This the complete opposite of how many internal freezer ice makers feeler arms work. The freezer ice makers arms are up to stop ice from being made. This is not true for our freezers.)

3) Put the ice bucket back in the refrigerator.

4) Do as Harvy said: Press and Hold the Ice Selector Button. Yes, keep holding it. Keep holding. The white hard plastic "fingers" will start to rotate slowly. At one point while the fingers are rotating, you should see water quickly flow out and fill the metal ice chambers.

Note: The ice feeler arm may not move at all during this process. That is OK. If the feeler arm is in the UP position, that is even better.

5) Keep holding the Ice Selector button until the white plastic ice pushing "fingers" are COMPLETELY out of the water and ice chambers. You do not want ice to freeze onto the fingers, because then you will have another problem - ensure the fingers are not sitting in water.

6) Release the Ice Selector Button when the ice pusher fingers are free and clear of water

7) Close the ice maker door and wait for ice!

Give yourself 6 hours for ice - I say this so that you will not get too impatient to see if the ice maker is working. Also, the ice maker chambers have to cool down to make ice too.

Preventive Maintenance:

* If traveling weekly, like I did, EMPTY THE ICE MAKER and Turn it OFF!! This steps is listed in the manual for the refrigerator, If the ice maker is not regularly used, produced ice builds up around the feeler arm and may melt and freeze inside the feeler arm assembly.

* Use the ice maker! I now put ice in freezer bags or dispense them to throw at geese crapping all over my yard. :-)

* Don't turn the refrigerator temperature below 38 degrees. I did this when I first got the refrigerator and the ice maker stopped making ice. I turned off the ice maker off overnight and turned the temperature back to 38 degrees and in 24 hours I had ice again.

Hope this help. Your suggestions helped me. Thanks!!

the water intake is into a double valve at rear if i remember correctly. make sure valve has continuity.
otherwise, check water line in freezer is not blocked with ice
