Kenmore Elite 795.74025 not cooling enough

This unit is a bottom freezer with french doors on upper fridge. Over the past couple weeks, the temps have slowly moved up. After some troubleshooting, I’ve discovered that the fans for the fridge and freezer are not running. The compressor runs, condensor fan is clean and runs fine. It appears to be an issue with the evaporator fan - it is not running. If I place the unit in Test mode #1, the fan starts and blows air in both the upper fridge and freezer. When operating normally it does not.

I’ve check the resistance on the sensors for the fridge and freezer and while the voltage appears to be in range, the measured resistance is wrong and indicates a temperature far too warm. Logic would dictate that the fan would run constantly, but it is actually not running at all.

Is the issue with both thermistors/sensors? Seem unlikely that both would fail at the same time. Unfortunately, this would mean that the PCB is bad…

Any ideas?
