I can see that the pin that holds the ice chute door is loose because the plastic is broken where the pin is supposed to snap onto the dispenser housing. In the "Dispenser Front Parts" document W10141116 it looks like I need a new housing, which is item 1 on the diagram. However, this part does not appear in the list of parts I can order. How can I get a new dispenser housing? Is there a Whirlpool part# for this item? Or is there another solution to this problem? Do I have to order a whole new $500+ Freezer Door (part 2318425S)? Thanks so much!
