How do I adjust the temperature controls if my refrigerator is too warm or too cold?
If the refrigerator is too warm, adjust the Refrigerator Control one setting higher. If the freezer is too warm or producing too little ice, adjust the Freezer Control one setting higher. If the refrigerator is too cold, adjust the Refrigerator Control one setting lower. If the freezer is too cold, adjust the Freezer Control one setting lower. Wait at least 24 hours between adjustments.
