Product review (5 stars): Fixed ice cube issue
Ice cubes weren't dropping from tray, cubes were a solid chunk of ice. Swapped out ice cube unit and water valve to my Samsung RF4287HARS, which seems to be a common issue with this fridge. Worked fine for a day, got solid chunk of ice again. Read that the DA92-00233D regulates cooling AND heating, it also seemed to solve the issue for others having same problem as I. Ice is now dropping as normal since I installed this unit 2 months ago.
