The easiest repair I've ever done. I originally thought (after watching some youtube tutorials) I would need to replace the spring on the flap, but it is not accessible on our Samsung model. Undid the two screws holding the flap to the fridge door, pop it up off the other supports, and un-clip it from the power cord. Put the new flap on the same way and all done!
Delivery of the part was crazy fast too!
