Product review (4 stars): Excellent Replacment
Arrived 2 days after My Whirlpool refrigerator shelf inexplicably failed (I'm not particularly loving that fridge)! It's had several issues and is still pretty young. Went to the Whirlpool web page - worthless!  Found the shelf part number, 2304235K, from the original parts list - $56 on Amazon. Then found a cross reference to W10321304 on another web site. This is supposed to be a newer part number - It certainly proved less expensive. It arrived 2 days later and fit perfectly. Not certain, but it feels a little better made. Hope it works out better that the one it replaced.
