Samsung RS2533SW refrigerator is not cooling, freezer is working well. how to fix the problem. don't say unplug, I already tried many times for unplug for 15 seconds, 2 minutes, 2 hrs and overnight. The problem is still there, the refrigerator temp is 56F.

If your seals are good on the door and the fridge side is set for a mid range temp ck and make sure the fan is running in the fzr side. The fridge side steals cold from the freezer by directing air from the fzr to the fridge. Also make sure the fzr does not have an ice block in it the back will be frosted up and if you took the back shell off you would see the cooling coils frosted up real bad or even iced if you find this your refrigerator is going to stop working soon. The suspect parts are the defrost timer the heating element in the freezer located with the cooling coils and the defrost limit this is a nickle size disc with one wire running to the end of the heating element it kicks the element on and off to keep it from overheating the fzr. The defrost timer is usually located in the fridge side under the top or backside plastic it will have a slot in it that a flatblade screwdriver will fit it and you can turn it with audible clicks It kicks the heating element in for a few minutes each day if it quits it will not advance. Hope this helps all of the parts can be purchased and installed by the home owner good luck and remember to unplugg before delving into the elect parts.
