Product review (5 stars): Part works great. You MUST completely reattach the damper section.
Fixed the fridge - works great.

FYI: make sure you get ALL the screws back in correctly upon reassembly.

We missed one, and the Mrs. was worried about all the food spoiling, so we resolved to look for it the next day. Upon waking, we tried to get water out of the fridge: no joy. The not-completely-attached damper section had leaked air all night and let the fridge compartment (and the water line) freeze solid. The water filter housing had cracked from the ice, and had to be replaced. Another charge, another wait.

Fix it right and put it all back together when you're done and you should have no trouble.
