Strange, I just checking my freezer compartment in the home refrigerator, my freezer in the basement and the freezer compartment in my MH, all three of them are reading 28-26 degrees. I've never heard of a home or residential freezer going to 0 degrees. Foods will freeze at 31 degrees or lower, don't really see a need for zero degrees. My RV fridge takes approximately 6-8 hours to bring it down to operating temperature.
