I had the same issue, I was able to pull it open enough and aimed the hair dryer at the crack, eventually it popped open all the way. Make sure to put down some towels.
Mine is doing the same thing. 2 months old. Chatted on-line to Samsung last night. 3 different links. Still do not know why it is happening after only 2 months. Sounds like a fault of the design.
I have to defrost and reset; I will try this when I have some time this week-end. If it happens again, calling for a tech out for warranty
I had contacted Samsung support, which were of no help whatsoever. They suggested resetting the ice maker. I tried it and it did not work, which is why I had turned to this forum.
I did not want to defrost the entire fridge/freezer. At first, I tried putting narrow containers of boiling water in the ice maker, but it did not work. So, I pulled out the hairdryer. It worked great. Be ready with some towels though. It melts fast.
To do this, pull out the bottom drawer before starting and put a large towel on the (inside) bottom of the fridge. Put a small towel in the bottom of the ice maker. Then begin with the hairdryer. It doesn't take long, but be sure to melt the ice behind the ice maker (inside). Once you start melting the ice, you can feel it in the back of the unit. It gets pretty hot in the ice maker pretty fast.
Once defrosted and dry, reset the ice maker and re-insert the tray. Samsung has a great diagram on how to reset the ice maker. I cannot find the link, but it has very helpful pictures on how to reset it. Maybe the Samsung Moderator could post the link in a reply.
That did the trick - until next time. We are making ice again. I just now opened up the ice maker - and I am happy to report that I don't see any frost building up - and a full tray of ice. Hopefully, the problem is solved. Good luck.
