Possibly the best money I've ever spent! If your freezer side is frosting up while your fridge side isn't cold, this is likely the culprit. Easy to install, and cheaper than the minimum service call just for someone to take a look. Before you give up and buy a new one, try this.

Apparently the presence of the part caused the to cease malfunctioning. I have it in a drawer, in case the refrigerator needs a reminder.
