My samsung rf265ab did the same thing after I was cleaning it and the door was open for an extended time. I noticed the the light bulbs looked good and also notice 2 tiny black buttons between the light bulbs. They were slightly extended. I pushed both in and when I opened the fridge again the lights were working. Don't know if I fixed it or just a coincidence.
That company is being sued in a class action for their ice makers. With that in mind there is a tecnical bulletin for certain units and the repair is a three step process, defrost the unit and check the ice maker fill tube. They tend to move out of position, press it back into position and use a caulking sealant around the tube, the last thing is to check for a lip around the ice maker holder in the freezer, if it is present you need to trim it back. As a last resort, you can change the main board.

The ice maker on our samsung 2012 fell apart. ... Skipping to the pertinent points made this a 5 minute repair ...
Sounds like your Samsung RS21 has devoloped a known fault.
Your frdige will be cold in the drawers but not cold above this? Also there is ice around the pipe behind the drawers. it is the ice hitting the fan that is the noise and eventually stops the fan which pushes the cold air around the frdige.Samsung have extended their warranty to 5 years to cover for this.
You need to call the Samsung customer care team 0845 7267864 and should be repaired free of charge. - mine was. When you call, you need the full model number and serial number. my serial number was on the outside left hand side of the fridge. The engineer comes out within a day or 2.
