Icemaker

You might have a frozen line. Also and this seems more important to you its prob to cold, Trust me to cold of a refrig will cause hollow ice cubes first leading to a frozen line. Clean your coils, if you have another refrig empty out into that, unplug it leave doors open a couple days. If you can get to water line use a hair dryer from a distance defrost line, turn down freezer half knotch 1 full one at maximum. should fix issues, especially if filter already changed. If this all check prob a clogged line, not just frozen.
