My fridge won’t cool. The freezer has been steady at -2 but the fridge side has been climbing the last week from 50 to now 58 today. It’s a samsung rs267tdrs/xaa refrigerator side by side. The evaporator seems to be running and the fan next to it is running. I cleaned the coils off and have also tried unplugging it for hours and replugging it back in. The door liner is not hot and is clean, the doors seem to be sealing fine. I took a look at the cpu board panels and two fuses that I could see did not look blown.
Is this something I can fix myself? It seems like it is just a sensor? What else can I check? I have fixed my washer and dryer a few times thanks to this site, but never the fridge.
