Brand: GE
Model Number: GSS25QGTABB
Main Symptom: Refrigerator not cooling
What happens & when: Had a power serge and fridge stopped working. I replaced the control board and it came back on but would freeze in the fridge portion. I then replaced the damper box but that did not fix the problem. What should I look at next.

Check the thermistors in the refrigerator. If you have a faulty thermistor it will keep the damper door open which would cause this issue.
