The samsung refrigerators temperature in side is 58 deggrees F.

5 for both freezer and fresh food side. This corresponds to about 37 degrees in fresh food side and 0 - 5 degrees in freezer. Check for blocked vents from and to the fresh food side and return to freezer. Most problems occur because these vents are blocked and/or overstuffing of freezer and fresh food side. The air has to have room to circulate. Another thing to check is if the condensing coils are dirty. Normal access to the condensing coils if yours has one is inside the cardboard cover on the lower back side of the your refrigerator.
Hope this helps

If your refrigerator is really full with items, lower the temperature a bit. ... they're not going to go bad because they were at 41degrees for a few hours.

problem thermostat call a technician to properly diagnose and fix

I have a similar Samsung side by side refrigerator and last year had the same problem. i.e. the fridge side ices up.
In our case this eventually led to the circulation fan to stop working and the temperature to rise, all food spoiled. This was caused by the defrosting heating element failing due to a faulty sensor within that component.
Samsung are very aware of this issue and direct contact with their customer services resulted in an engineer's visit and a free of charge repair. We also were given a voucher for the loss of food caused by the failure of the fridge.

If you put hot food in the unit it can take a full 24hrs or more to come back down to temperature that is why you don't do that, anything in your fridge that can spoil is most likely spoiled.

check the freezer evaporator thermistor on the top left corner clipped to the evaporator,if its not 16k ohm when at 32 degrees in a glass of ice water after 4 minutes it will defrost too many times and cause this issue,you need to unplug the J1 connector on the mother board in the rear behind the cover and check terminals 4 & 5 un the plug,not on the board though

It sounds like the thyristor or temperature unit is malfunctioning have it checked out and replace it if faulty.

1. The first thing you must know is that your refrigerator should be set at 37-38 degrees. Anything at 40 or higher and you are risking food born illness (food poisoning) or spoiling your food. Place your magnetic thermometer in the refrigerator.

2. Set your dial on your refrigerator to the second lowest setting. (If your refrigerator is already equipped with a digital thermostat, simply set it for 37 or 38 degrees and do not move on to the next step)

3. After 2 hours, check your thermometer reading. If your reading is 38 degrees, there is no need to go higher and you are ready to put your groceries in. Be sure not to open and close your refrigerator during these two hours or your temperature reading will be incorrect.

4. If your reading is higher than 38 degrees, move your dial up to the next coldest setting and repeat the steps every two hours until you reach the correct temperature for your refrigerator.

5. Once you have reached the correct refrigeration temperature for your refrigerator, place the magnetic thermometer in the refrigerator permanently and watch for changes.

Typically, your refrigerator temperature will need to be adjusted with the seasons, a higher setting in the summer and a lower setting in the winter.
