I have a 2 year old GE side-by-side refrigerator (model GSS22GSPC) that sporadically fails to cool. It might work fine for a day or a week, then I open it and it's 40 in the freezer and 70 in the fridge. Another recent symptom is that the digital readouts for setting coldness sometimes don't light up when the door is opened. Most of the time (possibly always?), cold air starts flowing if unplug the fridge, then plug it back in.
I don't think the compressor is bad, since it often is blowing cold air in the freezer, but not in the fridge. The problem also does not appear to be related to the door being poorly adjusted, or with the unit getting electricity (the lights come on fine).
About 9 months into it's life, it started doing this same thing. I had a warranty repair done on the unit. The repairman checked everything and could find no problems, so he replaced the main control board. The unit worked fine for the past 13 months. I replaced the control board, but the problem persists. What else could possibly be going on with this unit???
