Precautions while using Refrigerators
The temperature within your refrigerator should never exceed 40 degrees Fahrenheit. Place an appliance thermostat inside the refrigerator to monitor the refrigerators temperature. An appliance thermostat will be of great help in the event of a power outage. Once the power comes back on, check the thermostat to make sure the refrigerator returns to 40 degrees Fahrenheit. Food left inside the refrigerator for more than two hours at a temperature higher than 40 degrees Fahrenheit is not safe to consume due to bacterial contamination.
