Product review (3 stars): It's good they're so easy to replace
This will be switch number four, as they seem to last us only a year or two before they die. I don't know if the design is defective or we're just exceptionally hard on the switches, maybe by slamming the (packed to the gills and heavy) fridge door shut. Edit - Took the last one apart, and as other reviewers have noted, one set of the contacts inside the switch had burnt away. So it's got nothing to do with how we're using the  fridge, I don't think.
