Product review (5 stars): perfect replacement, but what part do you need?
Before you buy this for your hollow ice cube problem read my review!  we purchased the ice maker and replaced the old one but still had the same problem with hollow ice cubes, so we called SUPCO and someone told us that it was possibly the water valve solenoid, so we replaced that --still hollow ice cubes.  Finally read in some forums on hollow ice cubes and one suggested taking loose the water flow and seeing what that looks like-- ours was very low, so we replaced the water filter and finally got giant ice cubes that are no longer hollow!  Actually after my husband saw the inside of the old ice maker he would not have sent the new one back, because the old one was corroded and full of deposits-- disgusting, so its a good thing we bought a new ice maker --but it didn't solve the problem of the hollow ice cubes --we needed a new filter.
