If you have an old refrigerator or one of the small dorm refrigerators, you know all about the frost that forms around the coils that cool the freezer. If you let it build up long enough, the frost can get 6 inches thick and eventually there is no room to put anything in the freezer. This frost forms when water vapor hits the cold coils. The water vapor condenses -- turns to liquid water. Think of the water beading up on a glass of iced tea on a summer day -- that is an example of water vapor in the air condensing. The same thing happens on the ice-cold freezer coils, except that when the water condenses onto the coils it immediately freezes. A frost-free freezer has three basic parts: * A timer * A heating coil * A temperature sensor Every six hours or so, the timer turns on the heating coil. The heating coil is wrapped among the freezer coils. The heater melts the ice off the coils. When all of the ice is gone, the temperature sensor senses the temperature rising above 32 degrees F (0 degrees C) and turns off the heater. Heating the coils every six hours takes energy, and it also cycles the food in the freezer through temperature changes. Most large chest freezers therefore require manual defrosting instead -- the food lasts longer and the freezer uses less power.

My food in the freezer looks like it has been snowing in there. Can anyone tell my why?

This is freezer frost. What happens, essentially, is that on a warm or humid day when you open the freezer a lot -- or more commonly when you accidentally leave it ajar (when the edge of a package gets stuck in the seal as you close it, for example) -- condensation builds up as warm, humid air hits the cold, dry air inside. It collects on the inside surfaces. This condensation then quickly re-freezes from the cold of the freezer itself or the frozen food under it, and it forms this "snow". Unless you have a frost-free freezer that automatically prevents this, you should defrost a freezer a couple times a year (as the ice builds up) by emptying it and turning it off for a day. Once it's clean and dry, put the food back in. Obviously, try to do it when there's not much perishable food to deal with. A self-defrosting freezer uses special "evaporation coils" to aggressively pull the moisture out of the air, keeping this buildup from occurring.

How does a freezer preserve food?

All food will break down overtime as micro organisms go to work. At normal room temperature, the bacteria thrive, and depending on the food, they will multiply quickly to dangerous levels. By freezing the food, the micro organisms don't die, but they will multiply at much slower rates, meaning the food will keep longer.

Is there anything I can lay on our non-frostfree freezer shelves to keep them from getting thick frost on them?

Not that I know of ! If it is frosting up thickly often, then you need to replace the seals around the door. You are better off just buying a new freezer. Chances are it is getting old and wearing out, and it is obviously not very efficient any more.

Why is your freezer cold but not your refrigerator?

Strangely enough fridges and feezers actually need to have stuff inside them to work properly. A fridge or a freezer will work best when they are about 60-75% full. If they are too empty or too full then they won't be as cold.
