Yes, it is possible to switch off a fridge without unplugging it by using the temperature control settings. Most refrigerators have a thermostat or temperature control dial that allows you to adjust the cooling level. By turning this control to the "Off" position or adjusting it to the lowest setting, you effectively switch off the cooling system while keeping the fridge plugged in.
Keep in mind that the exact location and appearance of the temperature control may vary depending on the refrigerator model. Typically, it can be found inside the fridge compartment or on the backside of the unit.
If you want to turn off the freezer compartment separately, some refrigerators also come with a separate temperature control for the freezer section, which can be used to disable the freezer while keeping the refrigerator running.
However, be cautious when switching off the fridge for an extended period, as perishable food items may spoil if not refrigerated. If you plan to turn off the fridge for a longer time, make sure to remove all perishable items, clean the fridge thoroughly, and leave the door slightly open to prevent mold and odors from developing inside.
