Freezer cold, fridge warm
Your 99 regrigerator should not be bad, even though it could be. I would check with a thermometer to see just what the inside temperature is for both the freezer and the cool box. I would not expect the freezer to be as cold as it should, but ......... Is there any smell of ammonia or any yellow powder in the rear of the unit inside the access panel? Or is the ammonia smell inside of the refrigerator. Those are indications of a loss of coolant, so we will hope that isn't there. A plugged cooling coil might cause what you have. If that is the case, sometimes it can be corrected by removing the refrigerator and turning it upside down for a few hours, then reinstall. If there is some crystalization of the ammonia that might clear it, and if you are lucky, stay that way. Keep us all posted on this one as it is an unusual problem?
