Depending on the size of your household, your grocery bill can sometimes outpace utility costs or other expenses, making it one of the biggest monthly expenditures in your budget. If you've spent that money on organic, fresh produce, watching it go bad faster than it should can be a frustrating experience.

If your lettuce is getting icy or your meat is smelling a little fishy, the problem might be your refrigerator's temperature setting. While many newer fridge models have digital thermometers that make checking for the correct temperature easy—it should be right around 37°F, with your freezer at 0°F—others have a manual dial that offers ambiguous settings numbered from one to five or one to 10.

Fortunately, there's an easy way to make the knob match your ideal climate. Refrigerator thermometers are available at home goods stores or online and provide a digital readout of the refrigerator's interior that's usually accurate within 1°F. Leave the thermometer on the middle shelf to get the correct reading.

Once you have the appliance set, be sure to check it periodically to make sure it's maintaining that temperature. Packing too much food on your shelves, for example, tends to make the interior warmer. If the coils need to be cleaned, it might be retaining more heat. Kept at a steady 37°F, your food should remain fresh, safe, and perfectly cold.
