Product review (1 stars): bad batch of plastic?
Plastic eroded very quickly (2 weeks) on this Cam, fridge door quit closing on its own even though this one was specifically designated for my model Whirlpool Gold fridge.  Ended up utilizing another Cam from variety pack of Cams I purchased to replace this one.  The plastic in the 2182179 must be different than other Whirlpool plastic molded Cams.  Wish I could get my money back.
