If you notice that your refrigerator isn’t staying as cool as it needs to, check to see what your refrigerator settings are. Use an appliance thermometer to make sure that fridge temperature is below 40ºF.
If the temperature is above 40ºF, try adjusting the settings, and wait 24 hours before checking again. However, if your fridge is already on its lowest temperature setting, or if adjusting the setting doesn’t fix the issue, read your owner’s manual for more detailed information and troubleshooting.
