Our GE at home turns out to have been made by Samsung. I would not buy another. The ice maker design is poor and loud and it breaks... I’ve torn it apart and repaired it twice in 8 years. The evaporator drain on Samsungs is known to plug and ice up, and ours did. Everything had to come out and go in ice chests for several hours while I figured out how to get the inside back panel off to access the evaporator. It wasn’t easy. Aligning the panel to put it back was even more difficult.
The drain heating device that’s supposed to keep it from ice-plugging is simple and ineffective. It’s at the bottom of the evaporator, and has a tongue that extends into the drain port to keep it ice free. The tongue isn’t long enough.

We’ve had no more issues, at least not with the evaporator system. The ice maker is still loud enough to wake the dead, and still overfills and frustratingly clogs.
Your symptoms are slightly different than ours, where our deli tray froze to the bottom. But the cause of that was water that couldn’t escape the evaporator by normal draining during defrost cycles, and overflowing. This compromised the entire cooling process. Excess water then drained down the back Inside wall of the fridge, pooling on the bottom where the deli tray froze to it. So there’s a chance your warming scenario could be from a plugged evaporator defrost drain.
