how long should an unplugged Sub-Zero refridgerator go from 68 degrees to 34 degrees?

The time it takes for an unplugged Sub-Zero refrigerator to go from 68 degrees Fahrenheit (20 degrees Celsius) to 34 degrees Fahrenheit (1 degree Celsius) can vary based on several factors. The ambient room temperature, the amount of food or items inside the refrigerator, and the insulation quality of the refrigerator are significant variables affecting the cooling rate. Generally, a well-insulated Sub-Zero refrigerator without any items inside may take several hours to reach the lower temperature range. However, it's important to note that Sub-Zero refrigerators are designed to operate continuously, and unplugging them for extended periods is not recommended for optimal performance and food safety.
