What level should I put my refrigerator on the control panel? I have an old model from your refrigerators and its not cooling enough on the refrigerator, the Freezer it's fine, it freezes the ice cubes and everything but the refrigerator I have no idea why is not cooling. I already cleaned the condenser but I have no idea on what level to put it... I have Off, then a long blank, then 1 to 8, but I'm not sure how to set up that control panel to see if it gets colder.
