I replaced the icemaker and it worked fine for a few hours but then the plastic bin under the fill tube iced over and water overflowed when the icemaker cycled. It looks like the water comes from a tube at the top of the freezer and goes into a plastic bin with a small hole at the bottom that drains into the individual icecube trays. The hole at the bottom keeps freezing up so the next time the freezer cycles water overflows the bin
