refrig and freezer not cooling /freezing
by Tim A
i have a GE frig, model gss25sgpass. a few wks ago i replaced the main board since the frid and freezer werent cooling / freezing. that worked. but the fresh food bin continued to freeze veggies and so i replaced the fresh food thermister by cutting out the old and splicing in a new one (i could tell it was defective according to your description - domed end / black surface where wires insert into thermister). its been 2 days since i replaced the thermister and now the freezer and frig arent cooling / freezing. could there be moisture on the splice connection of the new thermister? did i just blow out the control board i put in a few wks ago?
When you spliced the new thermistor did you use silicone as I describe at the end of the video on this page How To Test A Thermistor On A GE Refrigerator
In any case I am almost sure this isn’t the problem. Poor airflow will cause the veggie bin to freeze more often than the thermistor. If the entire fresh food section were freezing then I would look at the thermistor. With that being said it couldn’t hurt to replace it since it was on of the faulty thermistors.
Check to see if the fan inside the freezer is running and if not take a look at this page GE Refrigerator Fan Motor Diagnostics
Ice may be blocking airflow, remove the back wall of the freezer and check for heavy frost that would block airflow.
My personal computer at my house is in the shop and I have to use the one at work so it may be a few days between responses. Sorry for any inconvenient.
