Neil December 16, 2020 for Model Number DV48J7700EW/A2 Purchased the board (part #AP5916808) for my Samsung Dryer Model #: DV48J7700EW/A2 Trying to replace the board that is faulty in my dryer - how do I remove the knob from the current set up? By twisting or by pulling? I don't want to break anything. Any further tips or steps on how to replace the user interface board would be greatly appreciated!
