Over the last several months my LG LSXS26326/00 has been making a clicking noise before ice cubes are dispensed (ice maker working, but noisy). When hearing the first click open the freezer and observe if the ice maker paddles are moving smoothly and listen for the clicks. If it jerks with each click noise, the plastic paddles are most likely somewhat stuck. When it is stopped, gently push the paddles forward and backward. Do they move easily? If not, you have the same problem I had. There is mineral residue or plastic contamination or moisture in the areas (bearing) where the paddles travel. OK, how do you fix that?
Loosen the motor/tray/paddle assembly by removing the two screws. I took and cleaned as much of the minerals off on the end where the water is dispensed (right side). Then I took and sprayed a small amount of WD40 into a bottle cap. With a flat toothpick (big end) I dipped the toothpick into the WD40, which collected a small amount of oil on it. Then I tipped the assembly back and forth to allow each application of oil to run down into the bearing surface. After several applications of oil (a small amount) the paddles loosened up. What this appears to have done is 3 things; loosed the mineral deposits, loosened the plastic that may have worn off, and with the oil on the bearing it will prevent the accumulation of the slight amount of water to dry out and create mineral deposits.
Did it work? After an hour or two after reassembly, insert a straightened paper clip into the test hole for 10 seconds. Then watch and listen for several minutes. The paddles will start to move and the ice will be dispensed - be patient. Were there any clicks? No! Where ice cubes dispensed? Yes? Fixed? I think so!
Long term - 48 hours and no clicking of ice maker! Success.
Maybe this should be an annual maintenance procedure. This procedure might save you a $100 to $200 depending on where you purchased the replacement - more if you had a service call. Remember, if you have any mechanical and electrical skills, you can do this. It is not much more difficult than replacing the water filter or cleaning a washer drain filter on a front loading washing machine. Good Luck!
