The refrigerator is an Amana BX22TW. The problem is associated with the icemaker.
We opened the freezer door and found a lot of heavy frost that was in the
1/2 of the freezer that holds the icemaker. Most of this was almost fluffy. It was in the ice tray and on top of the ice that was in there. It was also on the back wall of the freezer and it coated frozen packages that are in that part of the freezer. There was a little hard ice that had formed on the lip of the ice container. The first thing I did was to shut off the water supply at an eternal filter and raise the arm to the off position.It is not a case of the water just overflowing. The ice in the container was not frozen together as if water had been running into the cubes that were already there . Some of the cubes were stuck slightly stuck together but no more solidly than what happens sometimes just from the defrost cycle. the ice is clearing up by itself either due to the defrost cycle or just sublimation.
I have not tried to turn the water on again yet. What is the most likely cause of this? I don't want to start shotgunning a repair/replacement.
