Monogram ZISS42DCASS Side by Side Freezer is around 5degF, Fridge is around 45degF

Hi, I am trying to fix a GE Monogram ZISS42DCASS side-by-side fridge where the freezer temperature only gets as low as 5 degrees F, and the fridge only gets to about 45 degrees F, with both of the temperature controls set to 9 (max).

I have checked and cleaned the condenser coils and fan - all is good.

I have checked the evaporator coils and they are clean with no ice build up. The defrost timer and heaters all seem to work well.

The door seals are good and there are no obvious blockages with the airflow.

I thought the freezer temperature control thermostat/capillary may be reading the temperature incorrectly. I bought a new part but before fully installing the capillary into the freezer section, I left it in the fridge and powered it on. The compressor ran and the freezer temperature went down to below zero. At that point I stopped and routed the capillary into the freezer section. Unfortunately the freezer then still only went down to 5deg. I then thought that maybe the evaporator fan was not blowing enough. I checked the fan and it blows well. The last though I had was to see if there was air getting to the fridge which is controlled by a capillary/damper. There seems to be adequate airflow in the fridge.

After all of this, I am a bit stumped of what to try next. Does anyone have any suggestions?

Thanks, John
