Product review (5 stars): Hollow ice cubes?
I didn't even know it was possible.  The ice maker in our old Amana started dispensing hollow ice cubes.  While that may have been a novelty at first, it got very old very fast.  Eventually it stopped making ice completely.  We called an appliance serviceman who said he would have to charge over $300 to resolve the issue, but didn't have the part on his truck at the time, so he gave us the part number and told us where we could buy it.  Well, a few clicks of the mouse reveled a 30% savings from Amana on Amazon over the vendor that he had recommended.  The valve was here in a couple of days and I only spent 25 minutes installing it.  Now, at a glance, there are some subtle design differences when you compare the old valve next to the new one.  I thought it was cosmetic only, but noticed right away how much quieter the new valve is when filling the ice maker.  Now that old ice maker is spilling out solid ice cubes like it did when it was new.  The best part is I saved almost $300!
