- Spring & Fall: Mild kitchen temperatures mean your fridge doesn’t have to fight as hard. Check the actual temperature with a cheap appliance thermometer and nudge the dial a little warmer if it’s running colder than necessary.
- Summer: Hotter kitchens + more door openings = warm air rushing in. Set the fridge closer to 37°F, keep it well organized for good airflow, and store drinks toward the back where it’s coldest.
- Winter: If your fridge lives in a garage or cold basement, outside temperatures can drop low enough to trick the thermostat. You might see milk freezing or lettuce turning to ice. Raise the setting toward 40°F to prevent overcooling (and save energy).
How Much Can You Actually Save?
Energy experts estimate that dialing in the correct temperature can cut a household’s refrigerator energy use by up to 10%. For the average home, that’s $100 or more saved per year—and sometimes much more if your settings were way off. Multiply that by millions of households, and the collective impact is enormous.
