Samsung refrigerator RF323TEDBSR/AA fridge/freezer temperatures constantly fluctuating

Brand:Samsung
Model Number:RF323TEDBSR/AA
Main Symptom:Fridge and freezer too warm- fluctuating temps
What happens & when:

Hi, I have a Samsung refrigerator (2013) #RF323TEDBSR/AA and the fridge/freezer temperatures are constantly fluctuating. I bought 2 sets of thermometers to use in the fridge/freezer because the digital display says they’re both at the temps I set (34° &-2°), but they’re not. Fridge is between 37°-50° & freezer is between -5°-39°. I noticed that food in the fridge was either going bad sooner than expected or ie: I bought a bagged salad mix and not 24hrs later it was almost completely frozen. The freezer was keeping the solid food frozen, but not soft things like ice cream or keeping the ice from ice maker frozen. (Ice maker works fine, and ice comes out solid) About 1 1/2 months later I found water in & under the crisper drawer, which we used a water leakage and moisture kit w/secondary heater. We have replaced the following: a kit to keep the evaporator coils from icing up (which included a secondary heater for the top of coils), evaporator fan motor, defrost heater, defrost bimetal thermostat, 2x temperature sensors (1 by the evaporator fan in the cover panel & 1 on the top right of the evaporator coils) which was all behind the evaporator cover panel inside the fridge at the back. It didn’t work. When I’ve Googled the problem, it now says that I need to change the Electronic control board, Display control board, the inverter board, &/or the Compressor overload protector. I don’t know what to do. As far as we can tell, the evaporator coils are not freezing up and there’s no water in the fridge, it’s just the temperature issues with the display not showing the correct temps. The digital display works fine, can use all the features, and throughout everything, there’s not been any error codes. Everything else seems to be working fine as far as we can tell.

One other thing, while I was researching this problem, I saw that one of the indicators of many different issues was if the unit was making noise. Unfortunately, it’s impossible to use this for a way to detect an issue due to this unit has been extremely noisy since day one. I’ve called and had repair technicians come out 5-6 times when it was under warranty because it was so bad. They all said that it was an unfortunate but normal thing with the newer refrigerator units, and there was nothing that could fix it.

I apologize for the lengthy post ~ just wanted to make sure that all the information was there.

I would greatly appreciate any help with this!

Thank you,

Angel
