Ice maker will not push out ice cubes once frozer

If the auger motor won't turn by hand, it's possible that it is frozen and needs to be removed and thawed out. You can try spraying it with cooking spray after it's dried out to help prevent future freezing. Before removing the auger motor, make sure to unplug the refrigerator and turn off the water supply to the ice maker. You may need to remove the ice bin and any surrounding parts to access the motor. Once you've removed the motor, you can thaw it out by leaving it at room temperature or using a hairdryer on a low heat setting. Be careful not to overheat the motor. After thawing, you can test the motor to see if it's working properly. If the motor still doesn't turn, it may need to be replaced.

You need to replace the water valve

If cubes are very large the ice maker may be overfilling and need the fill adjusted to allow less water into the maker. Otherwise check the fill tube (runs from the back wall to ice maker) for loose connections or cracked tubing. (In this instance the cubes would be smaller than usual.) If neither of these is the source, then look up to the highest point of ice (water flows downhill) for the origin. Suspect a stopped up defrost drain. Thaw and clear ice, then clear drain tube (DO NOT use a wire for this) with warm water and a turkey baster. Once water is flowing through tube and into drain pan under the unit the problem should be solved.

Is there frost buildup or the trigger obstructed?

remove cube tray from ice maker. clean with limeaway adn rinse. Spray with a light coating of PAM cooking spray. wipe dry and reinstall. be careful not to damage the sensor ( in center of tray)

The fill valve for the ice maker could be stuck partially open and dripping into the ice maker. If this is the case shut off the water line to the ice maker and if the water stops you will need to replace the ice maker fill vavle

Each mold tray has a heating element that is turned on to free the ice cubes from the mold tray and allow them to fall into the ice bucket when the tray is rotated into harvest position. Sounds like that is not being turned on... or is defective..

I removed the entire unit again, looked at it, removed the front cover, and decided I wasn't going to take anything else apart. When I reinstalled it in the refrigerator, it started working again. Possibly the wire connectors just needed plugging in the clean them again.

It is quite possible the water line near the ice-maker is frozen. I would try a warm hair drier to thaw it out.

When my repair tech came out, he showed me that the fill tube sometimes retracts toward the rear of the freezer. He simply pulled it forward with a pair of needle nose pliers until it rested in the delivery reservoir. This placement allows the detector to know when the tray is full and shut off; thus not overfilling the freezing tray and/or splashing additional water onto the freezer wall and into the ice cube drawer.
