number up or down on the refrigerator
If you turn the dial to number 0, that effectively turns the fridge off. Setting the dial to 9, the refrigerator will be working at its max capability. Your personal temperature setting will depend on how much food is kept in the refrigerator. If your fridge is packed with food, it needs to be on a higher number setting to maintain a low (colder) temperature. The temperature controller dial or slider on your refrigerator is a thermostat. It kicks the compressor on when the refrigerator is not cold enough.
