Hi, my refrigerator recently stopped cooling. The freezer was still working properly. Found that the area outside the RC evaporator cover was icy. I let the entire refrigerator/freezer thaw out and plugged it back in, seems it starts to get cold at first, but only gets to above 50-52 degrees before it stops cooling any further. Opened up the evap cover and took the attached picture. I don't believe the fan is running beyond the initial run. I ran through some of the diagnostic tests after letting it thaw for about one day and the results are attached.

My fairly uneducated guess is that it is a a thermistor or control board causing the issue.

I'm also not sure if/how the ice maker tray thermistor diagnostic reading "OP" could affect RC cooling.

Looking for advice on how to confirm my problem or what next steps to take.

We've had this refrigerator for about two years. The temperature in the middle of the refrigerator is about 55 degrees. The freezer is working fine. We had a tech come out and he shotgunned the fix by replacing the control board and UI board. That did not resolve the issue. I'm going to have...

I wouldn't think so, is the ice maker still making ice?
