Greetings!
Let us help you by providing the details you need for your Samsung refrigerator.
In general, there are screws at the ends of each door handle. These screws will need to be removed for the handles to come off. I have shared this model's user manual link below. Please turn to pages 28 - 30 for a visual guide. The steps outlined in the manual are for attaching the door handle, you may follow the steps in reverse order to remove the handles.
