RS25H5111BC temperature display incorrect

Temperature is set to 0 & 37. Every day or two, both sides will get warmer than that even though the display reads 0 & 37. I am able to have it function properly by removing power, restore power then reset the unit by pressing and holding fridge and freezer buttons. Compressors and fans will kick on and unit will be at proper temperature within 1 hour. After reset, the ‘true’ temperature will be displayed on the door display. Depending on how long the unit has be at fault, the displayed temperature will show 40 & 60 which is correct and verified by a thermometer. However, after a day or so passes, the both sides will be warm again.
