Answer to: Fridge isn't cooling and has ice build-up. How do I fix it?I couldn't find anything wrong, and didn't want to go to the trouble and expense of replacing the main board when there was no direct evidence that there was a problem with it, so I called in a repair person. He didn't initially know what the problem might be either, but he called the manufacturer (GE) and they suggested replacing two thermistors in the fridge (fresh food compartment). I was skeptical since I'd tested the thermistors and didn't see anything wrong, but told him to go ahead since there was no charge if it didn't work. It worked. So, if any one else has this model of fridge - or any model where the fresh food compartment (fridge) has its own evaporator coils but not its own defrost heater, then my suggestions are a) don't go messing around in the freezer, that's not where the problem is, b) make sure the evaporator fan in the fresh food compartment is working c) replace all the thermistors in the fresh food compartment.
