Ok, my freezer's icemaker is currently not working at all. The lever switches on and off with about the same resistance as it always has, but it just doesn't produce any ice. And the thing is, when it stopped working, the ice collecting binunder the icemaker was filled a little over half full with liquid water in addition to the ice. Since then the icemaker hasn't worked, and there hasn't been any more water leaked into the bin. With this failure symptomology, what's likely the part I will need to replace, the water intake valve, the Ice maker assembly, or something else unlisted?
