Hey Mr. Green,
What is the correct temperature for my refrigerator and freezer? --Phil in University Place, Washington
Set the fridge between 35 and 38 degrees Fahrenheit and the freezer at 0*F. Keep both filled--if necessary, with jugs of water or ice. It's an urban myth that cleaning the fridge's coils periodically with a brush or a vacuum cleaner will save energy, but standing there with the door open pondering what to eat is an indisputable juice drain.
