Samsung freezing in the fresh food section

Freezing in the fresh fruit section -10°F
Replaced evaporator cover in the fresh food section about six months ago and it came with the sensor imbedded But two weeks ago customer told me it started to freeze on the fresh food section. Diagnostic mode didn’t find any error codes and all the boards look great condition the one in the bottom left makes a little chirping but I’m guessing that’s normal because following the wiring diagram I noticed that the fresh food section refrigerator Temperature sensor runs to the main control board.
(Every time I forget anything in the question section on the website and it reloads telling me to add that information it will not display the brand even if I type out the whole thing seems like a glitch so I have to either go back and reload the whole page or put in a different brand on the brand selector and then the correct brand and the question description )
