I have the diagrams of the machine and see exactly what model ref and ice maker you have.
It is a little harder then most but still very easily removed.
First you need to remove the ice cube tray or bin under the ice maker, if you havent done so already.
You will also notice a few screws under the cover of the ice maker assembly near the very front of the cover. And even one on the right side of the cover. Remove those screws and pull the front cover off the ice maker cover.
With this off you will have enough room to remove the ice maker from the ice maker housing.
Now there will be either be one or two screws in the front of the ice maker. but these screws will actually go through the ice maker to the roof of the if the freezer
cabinet. The screws will be hidden. so with one hand feel the top front part of the ice maker for the screw (s) and once felt remove them.
You will notice the front end of the ice maker hang down a bit. That is good. That means that the ice maker is free and can now be slide to the front of the ice maker assembly until it just comes out. It is simply held in by clips and will come off. If it feels like it is held in by more then that, dont worry, it is isn't. Just give it a good grab and pull towards you.
With the ice maker freed you can removed the wired connection and pull it paste the fill tube coming through the top of the ref.
You should now be able to see if the ice make has frozen up entirely.
I have to say though, I have seen these machines a lot lately, and more specifically for the problems with the ice maker. Either maker too much or not enough ice.
Now before trying to removing any pieces and before working on this machine did you happen to notice a lot of ice build up in and around the ice maker? if so, I would first just try to manually defrost the ice maker and assembly with a hair dryer. Remove the ice maker bin and take the hair dryer and fan it all over the ice maker and cover, especially in the back of the ice maker assembly, for about an hour. This should defrost all the lines and evaporator. and fix the problem.
If no build up of ice and just a lot of ice being produced then problem is solely in the ice maker board. It si not receiving the signal form the ice maker that the tray is full as well as the bin and will continually make ice.
Again, like i said before, there is many known problems with this style ice maker. And not just with this make and model ref. It is with all french door ref with the ice maker in the top left of the ref. The problem is that in order to have an ice maker in the ref cabinet it has to have its own evaporator to produce the coldest temps needed to make the ice. And when they have done this it has caused problems with the production of ice and the way it actually makes it.
So whether it is making to much ice or not enough because it is frozen there will always be problems with this machine and ice maker in particular.
Please try to remove the ice maker in the way that I described and get back to me here if you have any other problems. Or if you would like to just defrost the ice maker assembly first that is recommended, that is fine too.
Just get back to me here and let me know how you make out.
