Hot food placed in the freezer can also produce humidity, which causes frost buildup. Other sources include malfunctioning defrost timers, heaters, and thermostats, according to GE.
Air circulation helps sublimate any ice or frost that may form on frozen items in the freezer compartment. While defrosting, this fan is stopped to prevent heated-up air from reaching the food compartment. Instead of the traditional cooling elements being embedded in the freezer liner, auto-defrost elements are behind or beneath the liner.
Defrosting a freezer with an improvised water collection method. In refrigerators, defrosting (or thawing) is the removal of frost and ice.. A defrosting procedure is generally performed periodically on refrigerators and freezers to maintain their operating efficiency.
Freezer Defrost: Early freezer units accumulated ice crystals around the freezing units. This was a result of humidity introduced into the units when the doors to the freezer were opened condensing on the cold parts, then freezing. This frost buildup required periodic thawing ("defrosting") of the units to maintain their efficiency.
In New York City, ice consumption increased from 12,000 tons in 1843 to 100,000 tons in 1856. Boston's consumption leapt from 6,000 tons to 85,000 tons during that same period. Ice harvesting created a "cooling culture" as majority of people used ice and iceboxes to store their dairy products, fish, meat, and even fruits and vegetables.

Most ice sensors are simple thermal switches and do not directly sense the presence or absence of ice buildup. An alternative design senses the impeded airflow and shuts off the cooling coils in a similar manner. Certain malfunctions of dehumidifiers, such as partial loss of refrigerant, can cause repeated icing of the coils.
Liquid nitrogen is only used when dry ice or other cryogenic approaches will not condense the desired gasses since liquid nitrogen will also condense oxygen. Any oxygen gas content in the vacuum line or any leak in the vacuum line will result in liquid oxygen mixed with the target vapors, often with explosive results.
