Freezer great Fresh Food Damper staying closed

GSS25UFMCWW GE Side by Side. Freezer works great, The refrig damper seems to be closing and not cooling food compartment. It doesn’t matter what setting one sets it at and I adgusted the fan blade to be closer to the opening for better flow. I know there is a temp sensor for it to acuate the vent. thanks for your help

I would pull the damper assembly out and look for a jamed door.
