Need to keep freezer at -6 F
My duplex fridge was set at -4 F on the freezer and 40 F on the fridge side, it feels cold but ice cream is softer than it should be and ice in the ice bucket stuck together from melting a little so I guess is not freezing correctly. I set it up at -6 F and now it is freezing fine but I know the temperature is set too cold! I know it should be at 0 F but am afrait if I set it to 0 F things will get spoiled…. what should I check? Thank you!
