Product review (5 stars): LG Model # LFX28978ST - So, this damn spring ...
LG Model # LFX28978ST - So, this damn spring breaks 2 months after the 5 year extended warranty runs out.  Couldn't find this part anywhere.  LG/Sears want you to buy the whole refrigerator Mullion for 60-70 dollars.  Spent the $6 on this and popped it right in.  Identical to the old spring that broke.
