Why is your home refrigerator not cold but the freezer section is extremely cold?

Possible causes:

• vents between fridge and freezer sections are clogged with ice. Warranty guy told me to unplug 24 hours, replug and everything should work out.
• Fautly thermostat
• Clogged/dirty evaporator coils (underneath in newer models, on back in older models)
• Bad "Adaptive Defrost Control Board", google it, it's an easy fix, about $35 on ebay, just make sure you get the right one for your model fridge.
