Product review (5 stars): Works.
Fast delivery.  Quality product.  Ice maker was getting cold but no water was pumping up and flowing over the ice shelf.  Disassembled and replaced this pump that sits in the water pan.  Unit hard snaps into the plastic shelf.  Force the old one out and snap the new one in.  The pump is 12V 1000mA 60Hz.  Do not test on a 12V car battery as others have mentioned.  After plugging the ice maker in it should fill the water tray and then pump water over the shelf, even with a warm box.  Hope this helps.
