This Whirlpool ice maker is compatible with the Kitchen Aid refrigerator model #KSRG25FKSS16.  Much to my husband's delight; after about an hour of searching through Amazon and Kitchen Aid, we tried the Whirlpool ice maker and because of our faith in Amazon's customer satisfaction policy, ordered the part on Friday and received it Saturday, a day earlier than expected.  It took thirty minutes to install and thanks to a little effort on our part and Amazon, we now have ice and have saved ourselves a couple of thousand dollars to replace the entire refrigerator.
