On a 1200, when the freezer is cold but the fridge section isn't, check the thermistor first. It should be clipped to the 2nd fin from the right. If it's loose, misplaced or bad, the 636658 thermistor fits and is in stock. If a good thermistor doesn't fix it within 24 hours, the cooling unit is likely getting weak.
