I have an older model (1994, I think) GE fridge (top freezer model) that recently decided it didn't want to cool the fresh-food section. I removed the back freezer panel, and sure enough, lots of ice build- up... I take it this means the defrosting system is compromised. Fine and dandy... I used the hair dryer trick, and over the course of the next two hours, I completely defrosted every bit of ice I could see in the freezer, made sure the evaporator fan was running, and made sure when I aimed the hair dryer down the vent, I could feel the air moving into the fresh-food compartment. I also vacuumed the coils underneath the fridge while I was at it.
Put everything back together, plug it in, and the fresh food section still isn't cooling (gave it 4 hours, and it got to a frigid 56 degrees). I can feel very little air moving out of the vent from the freezer to the fridge. The freezer fan IS running and blowing air into the freezer... I don't understand why its not also blowing into the fridge.
Is it possible that there was just enough of an opening in the air vent for the hair dryer to force warm air through, but not enough for the freezer fan to push cold air through?
I can replace the thermostat and related items, but if cold air isn't getting moved into the fresh food compartment, what's the point?
