Product review (5 stars): Count the coils in the photo if you don't see your model # listed.
Spring MHY62044106 is the correct spring for my LG fridge LFX28978SB (that was not listed in the description).  I chose it over another LG spring listed on Amazon by counting the coils in the photo compared to my old broken spring. The other spring listed is different.  The repair took 10 minutes, you have to first remove the two plastic retainers below the top and bottom hinges of the flap, they are snapped into place. Next you remove the two screws holding the center hinge, then slide the flap upward and put the ends of the replacement spring into the holes located just above the bottom hinge, slide the flap back down and re-attach the two screws, then snap the two plastic retainers back into place. Easy fix. The spring holds the flap in an open or closed position.
