Follow up.... The fresh food evaporator thermistor was off by 20 degrees to low. I'll pick up a new one tomorrow.
Side bonus to pulling out the ff coil to get to the sensor. I had been having water collect at the bottom of the ff section , I found the drip tray under the evaporator was rusted and had pinholes in it. after wire brushing it , it turned into about 10 holes in the pan ranging in size from pinhole to 1/16 inch holes.
I sprayed the rusted parts with rust converter and coated the whole bottom of the pan with marine epoxy. Not gonna rust out again. :>
