Well I've been Googling all morning, and have a few more comments and 2 corrections.
While I haven't found information specifically for our fridge model, I did find several other manuals indicating that the factory default options should all be set to 0. I wish I had confirmation that this information was true for my specific fridge, but at least I'm more comfortable with my initial assumption, now.
I also tracked down a refrigerator familiarization presentation for Samsung refrigerator repairmen, and have made 2 corrections to the modes and options below (corrections were made to modes 2 and 3):
0- Freezer thermister offset (varies from 0-15)
1- Fridge thermister offset (varies from 0-15)
2 - Icemaker Fill time (varies from 0-1; 0=95cc, 1=85cc)
3 - Icemaker Wait time (varies from 0-15; 0-13=58-45min, 14=59min, 15=60min)
4 - Icemaker Thermister Offset (varies from 0-7)
19 - ? can vary from 0-1
20 - Cool Select Zone Offset (varies from 0-7)
32 - ? can vary from 0-6
33 - ? can vary from 0-5
34 - ? can vary from 0-9
35 - ? can vary from 0-7
I still have no idea what the other modes (indicated with ?'s) are, or what their options might be. Since I found out the factory defaults were almost certainly all zeroes, at least I know we probably didn't inadvertently set our fridge to self-destruct.
However, I would still like to know what the other settings are if anyone knows.
