Product review (5 stars): it is a relatively cheap and easy fix. I have had other refrigerators with faulty ...
Exactly what I needed. Saved me $$$ on repair call. The left door mullion (tiny vertical bar) on my Samsung french door refrigerator was not "snapping back" when opened, and thus when closed it would crash into refrigerator not allowing the door to close properly. If this is happening to your door:  DO NOT buy the whole mullion, and DO NOT pay for a repair call. Order this spring. Search online for videos (there are several) of instructions for replacing.

It only took 10-15 minutes to replace the spring. The fallibility of this spring is definitely an annoyance, and should NOT be happening on all of these refrigerators. However, it is a relatively cheap and easy fix. I have had other refrigerators with faulty compressors and faulty ice makers, so I can't complain about a broken spring. And overall, I love this refrigerator!!!
