Ice not friezing completly and then water forms ice on icemaker ejection blades causeing them to get stuck and will not turn to eject ice ?

These icemakers are modular, just replace it by model number.

check for water flow at water valve or replace water valve

This is the procedure but yours seems to be a faulty Icemaker and needs to be replaced since your freezer is cold enough to make ice rapidly.

Check Temp inside freezer. It has to be down to about 10 or 15 degrees
This can cause slow ice making if its too high even tho its freezing everything else at 25 degrees
See if water is in icemaker.
Pour water in Ice Maker and wait to see if it ejects.
If it ejects thenyou need to replace water valve in rear bottom of fridge(Its the part that
attaches to water line out of wall)
If it doesn't eject then it is a faulty Ice Maker.
If its leaking same part needs replaced.The water valve at the bottom rear of fridge.

Scale builds up in older icemakers and some of the cubes stick and don't eject.
Check your ice maker after it dumps and see if its keeping some of the cubes and
not ejecting them.
There are cleaners for the Icemaker. Call your local Parts Store.

Please rate me if this helped.

Hello there
Here is some things for you to check ok
The motor turns the ejector blades which rotate until they contact the ice. Because the ice is frozen to the mold, it cannot be pushed out and the motor stalls. As the blades continue to press on the ice, the ice mold heater begins heating the mold. Once the ice loosens the ejector motor turns, the mold heater shuts off and the ice is pushed out.
so what i would first do is to check the mold heater to see if it is working
and if this is good than check the motor for the ejector blade and see if it is recieving power if it is have the motor itself checked to see if it is bad ok
I hope that this is very helpful for you there is still a lot more that can be checked but try these first ok
Best regards michael

Top 2 possiblities

1/ The motor that ejects the ice is shot.

or

2/ the heater element that melts the ice into pieces.

Here is where you can probably pinpoint problem.

Making Ice When everything is hooked up, the icemaker begins its cycle. The cycle is usually controlled by a simple electrical circuit and a series of switches. In the diagram below, you can see how the icemaker moves through its cycle.
"); //-->

• At the beginning of the cycle, a timed switch in the circuit briefly sends current to a solenoid water valve. In most designs, the water valve is actually positioned behind the refrigerator, but it is connected to the central circuit via electrical wires. When the circuit sends current down these wires, the charge moves a solenoid (a type of electromagnet), which opens the valve.
  
• The valve is only open for about seven seconds; it lets in just enough water to fill the ice mold. The ice mold is a plastic well, with several connected cavities. Typically, these cavities have a curved, half-circle shape. Each of the cavity walls has a small notch in it so each ice cube will be attached to the cube next to it.
  
• Once the mold is filled, the machine waits for the water in the mold to freeze. The cooling unit in the refrigerator does the actual work of freezing the water, not the icemaker itself (see How Refrigerators Work for details). The icemaker has a built-in thermostat, which monitors the temperature level of the water in the molds. When the temperature dips to a particular level -- say, 9 degrees Fahrenheit (-13 degrees Celsius) -- the thermostat closes a switch in the electrical circuit (see How Home Thermostats Work for details on this operation).
  
• Closing this switch lets electrical current flow through a heating coil underneath the icemaker. As the coil heats up, it warms the bottom of the ice mold, loosening the ice cubes from the mold surface.

-->The icemaker has a heating coil underneath the ice mold.

• The electrical circuit then activates the icemaker's motor. The motor spins a gear, which rotates another gear attached to a long plastic shaft. The shaft has a series of ejector blades extending out from it. As the blades revolve, they scoop the ice cubes up and out of the mold, pushing them to the front of the icemaker. Since the cubes are connected to one another, they move as a single unit.

"); //-->

• At the front of the icemaker, there are plastic notches in the housing that match up with the ejector blades. The blades pass through these notches, and the cubes are pushed out to a collection bin underneath the icemaker.
  
• The revolving shaft has a notched plastic cam at its base. Just before the cubes are pushed out of the icemaker, the cam catches hold of the shut-off arm, lifting it up. After the cubes are ejected, the arm falls down again. When the arm reaches its lowest resting position, it throws a switch in the circuit, which activates the water valve to begin another cycle. If the arm can't reach its lowest position, because there are stacked-up ice cubes in the way, the cycle is interrupted. This keeps the icemaker from filling your entire freezer with ice; it will only make more cubes when there is room in the collection bin.

This system is effective for making ice at home, but it doesn't produce enough ice for commercial purposes, such as restaurants and self-service hotel ice machines. In the next section, we'll look at a larger, more powerful icemaker design.

The mold heater is bad on this unit.

Sounds like the icemaker thermostat is opening too soon which turns the heater off.  The easiest thing to do is replace the whole ice maker which I have seen pretty cheap on ebay.  If you want you can test these part with an ohm meter.  Check the heater for resistance.  If it is ok then replace the module and thermostat.
