Maybe. Check to see if your freezer compartment and refrigerator compartment have separate controls. If so, it is possible that you’ll be able to effectively power down the freezer section by turning the thermostat off for your freezer. You may wish to turn off your freezer for variety of reasons including performing a repair or doing a manual defrost. Most fridge freezer combos operate from the same power source - so don’t unplug your unit from the wall.
