This question looks like it has been asked by others, but to no resolve. Jake, I see you have responded to them. The problem with some of the twin cooling plus systems from Samsung refrigerators having a normal temperature fresh food cabin and a warm (not frozen) freezer cabin have been left unsolved or no return with a fix or solved answer.
I just pulled the main control board (page 121, link provided below) and with a pair of magnifying glasses, inspected it and found no evidence of burnt parts. However, I did notice a strong smell of electrical smells. Hard to say it was a burnt smoky smell, but it is definitely more than any normal smell of electronics. Sticking it up to my nose, I couldn't isolate the smell to any one resistor, cap, relay, etc. It all smelled the same.
I have not found that the system has a tri-valve. My unit is a RF24FSEDBSR/AA and I don't see any tri-valve on the system or in the service manual. My understanding of this Samsung Twin Zone Plus cooling is that there is a evaporator coil in the freezer and another in the fresh food cabin. I verified it by the service manual and removal of the panels.
If there is no Tri-valve, then how does the freezer coil throttle refrigerant? Does the compressor speed up and slow down in order for that to happen? I notice on the freezer evaporator there is a large filter looking piece fabricated into the coil. Does that have something to do it similar to what the cap tube does? Page 20 is the refrigerant route diagram with the Yoder loop and such.
The compressor on this unit was replaced recently and the refrigerant was weighed in. I watched the tech recover the old refrigerant, do a nitrogen purge when replacing the filter/dryer and compressor. He used very little nitrogen as it was being brazed up, something I never see them do and know now why they do it. The system was evacuated to 252 microns and left to sit for an hour where it stayed under 500 microns. He did not replace the evaporator coils. This is a R134A system.
The tech is no longer wanting to work on it and it was replaced under warranty. If someone knows other than to pass this off to another tech, it would be nice if they chimed in.

Samsung RF18HFENBSR no cooling in freezer, fresh food fine
I haven't seen this before, where the freezer section is room temperature but the fresh food section is cooling just fine. I know these Samsung's have seperate evaporator coils for the two sections but I've never seen one section entirely off. Is this possibly due to a faulty two-way diverter...
