Frost on back of GE freezer section, no air blowing through open damper into FF section.........Hmmmm let me check my laptop and diagnostics to see what is wrong.

Meaning......... Refrig is a refrig. 90 percent of the problems are still easily diagnosed the same way we always have diagnosed them. I'm not too worried.

Was only way to do it. Was not that bad.
