Water dispenser fine but ice maker not working

I had water leaking in to the freezer compartment of my LG french-door refrigerator (LFD25860). It was getting on to food in the main basket and embedding it in a block of ice, as well as puddling-up on the bottom of the freezer and eventually blocking the door from closing properly. Because the water seemed to be covering a wider area than you would expect from a blocked defroster drain I didn't believe that my problem was covered by the other FixYa recomendations -and it turned out I was right.
The problem turned out to be that the "funnel" that the water flows through to fill up the ice tray was blocked by a solid piece of ice. When the icemaker would call for more water it would flow down the clear tube (with the open slots on the top) hit the ice and spray/overflow in to the freezer compartment.
The solution was obviously to pop this ice out, but that did require me to remove the icemaker from the wall of the freezer compartment. To do this you

• remove one screw from the bracket on the bottom of the icemaker
• Slide the icemaker up and slip it off of the two screws with rubber grommets on them.

By the time I got to that stage I had already removed the basket from the main drawer and removed the pull out tray/basket from the drawer pulls (by simply lifting the plastic tab on the right side and lowering the plastic tab on teh left side). I am not sure if you can remove the icemaker without this step, but I believe so.
Also, if you want to entirely remove the icemaker from the freezer there is only one plug with wiring to undo. As I mentioned above, the water hose doesn't not connect to the icemaker, it ends above the "funnel" and the water drops in. So removal is much simpler than you might expect.

As for the cause of the ice block, I am not sure but I believe it was either because the ice maker made too much ise one time and some cubes could not pop out. When additional water entered the funnel it didn't flow in to the ice tray, backed up, and froze in the funnel. The other thought is that when the door was not closed properly while our grandparents were visiting, the ice melted and subsequently re-froze causing the problem.
