Troubleshooting an issue with refrigerator (Maytag: MFI2569VEM1) where the fresh food section is not cooling properly. Freezer section is working fine. The actual temperature showing on panel is 0 for freezer and 38 for fresh food. The thermistor reading for fresh food when in diagnostic mode is 56! which is the true temperature of the fresh food area as measured with thermometer. And the thermistor for freezer is reading 1 which is correct and matches the actual temperature on the panel. All other diagnostic tests (fans, compressor, etc..)  are successful but the fridge won't automatically cool fresh food section because it thinks it's already cool enough. 

I first thought it was main board so I replaced it but same issue.

Is it possible that a fresh food thermistor can read proper temperature in diagnostic mode but send the wrong data to the board? 

​​​​​​​Thanks!
