Product review (5 stars): Perfect mistake
Bought it for my 1979 GE fridge but it didn't fit (my own fault, I guessed at the hole spacing).  Luckily, it fit my parents' 1990 RCA fridge just in time to fix the fridge before they left on a cruise.  They didn't have to worry about the pet/house sitter having problems with it while they were gone. Sometimes mistakes can be providential.
