ice maker not working?

Hi. The ice fill tube could be froze up. I have not seen many fill tubes freeze up on this models. Sounds like low water pressure is your issue, which can cause fill tubes to freeze. If your fill tube is frozen it will be frozen inside the freezer and you should be able to clear it out which out removing it. First make sure the filter does not need replaced. An old filter can cause low water pressure. The most likely issue causing low water pressure is the valve that brings the water to the refrigerator. This is usually a self piercing saddle valve and they only last about 5 years. I would replace that first. You can check it by shutting off the valve. removing the water line at the back of the unit then turn water back on and see what kind of pressure you get. This will work if your familiar with how strong of flow you should get. Before you do that you can check water pressure coming out of the water dispenser. The next thing would be the water inlet valve that the water line connects to at the back of the unit. I am also at attaching the ice maker diagnostic sheet so you can make sure there are no errors with the ice maker optics.
