Freezer cold / fridge warm

Model Number: GNE26GMDES
Brand: GE
Age: 1-5 years

Woke up this morning to find the fridge at 64 (freezer was still at -4). I would like to try and check a few things out before calling a repair person. I took the small back panel off and couldn't really see much. The fan that I saw was running and quiet, and the compressor was warm, but not so hot I couldn't keep my hand on it.
I also took a look at the motherboard and didn't see any obviously fried components.

I was reading articles on the Internet and some said to check the coils, but for the life of me, I can't figure out how to get the back panel off. Then I came across a post here that said something about removing screws from INSIDE the fridge.

Can anyone provide some guidance on what I can check before having to shell out some big bucks to a repair shop? I shouldn't be having these problems when the unit isn't even two years old (bought in in June 2014).


*********** UPDATE ***************

The fridge is now down to 41 degrees. How the heck can that happen? It's hard to t-shoot a problem that currently isn't there, but does that give some indication of what might be starting to fail?

Thanks,

Andy

You will probably have to wait for it to start acting up again before you can further diagnose the problem.
