I've battled this fridge. Same problem... changed out everything... diagnostics are limited. There are multipe fans in the freezer as well as two in the fridge, so don't just go on sound to determine if the fans are working as one could be working and the other one doesn't
Things Ive discovered and things I've tried
1) You need the diagnostic aid to really diagnose this fridge
2) changed all thermistors and raised the fridge evap thermistor
3) adjusted the express thaw temp( this may a problem if temp too high, need to do f/u with customer to check on success
4) replaced mainboard (fixed other issues but fridge still slightly above 41
5) ran the issue by the Ge Instructor from asti and he said to check the fridge evap fan and the seals around the evap cover. He said the fan and new cover comes as a unit and has been problematic... my seals seem fine and I am trying everything else first and have not found the kit the instructor mentioned
6)checked the 3way switcher valve for proper ooeration
and make sure you don't have the ice ball issue common to that design.
Appliantology is, however appliances are not, an exact science for I know there are a few refrigerators that actually hate me.
