How to set your refrigerator temperature
Purchase an appliance thermometer designed for refrigerators and freezers.
Place the thermometer inside a glass of water, and put the glass on your refrigerator's middle shelf.
Check the temperature on the appliance thermometer after 5 to 8 hours.
The temperature should register between 38 f and 40 f (2 c to 4 c) for safe food storage. Make sure that your thermometer is safe to put in water; not all are.
