Product review (1 stars): Does not directly replace LG 5231JA2006A.
It is *not* a direct replacement for the LG 5231JA2006A filter.  There are little notches on the LG filter that are NOT on this filter... It seems to fit - but when you try to use it - no water comes out.  When you remove it (after trying to run water through it) it explodes water all over you and your fridge.

I have a Kenmore french door refridgerator.

Buyers be warned.
