The defrost cycle is 20 minutes every 6 hours. Refer to those freezers with the direct cooling system. Means, there will be ice built up on the inside freezer walls and you have to remove it periodically. The frequency of defrosting depends on the operating environment of the refrigerator and the condition of frosting. This term refers to the freezers with the dynamic cooling system.
Because the frost will be on the evaporator hidden behind the fan motor. And there are heating elements to defrost the ice on it automatically. The defrosting process is controlled and completed by an electronic thermostat.
Defrost cycle is 20 minutes every 6 hours. We all know that the air around us contains moisture. Every time we open the door, the moist will rush into the freezer unavoidably, then cling to the sides and turn into ice.
As time goes by, the ice builds up and gets bigger. A lot of inside space will be lost. Drawers become harder to open; shelves become harder to slide. Inside air circulation gets poorer and cooling performance is not good as before. Higher energy consumption, which means more electricity bills. The compressor is overpressured with the longer working time. A shorter life cycle for the freezer. Automatic Defrost : has electric heating elements embedded in the evaporator coils.
If you are shopping for a new refrigerator, you may be wondering what a frost free refrigerator is. Terms like "automatic defrost," "frostless," or "no-frost" all refer to the same technology.

Uses more energy than manual defrosting - a frost free chest freezer will use up to twice as much electricity each year compared to a manual defrost model. Noisier operation since the freezer has to work harder to cool the interior after the defrost cycle. Sources are mixed on whether automatic defrosting helps prevent freezer burn or encourages it - some argue that the temperature fluctuations caused by the defrost cycle throughout the day can cause freezer burn. While frost-free freezers are convenient household appliances, consider the pros and the cons before purchasing one.

Manually defrosting a freezer is labor intensive and time consuming, taking as long as 24 hours each time.

Frost-free freezers typically cost more to purchase than their traditional counterparts. In addition, frost-free models generally cost more to operate. Based on the U. Energy Information Administration's September report, one frost-free cubic-foot freezer costing A frost-free model costs more to operate because it uses a heater to melt ice crystals, a fan to circulate cold air and sensors to monitor for frost buildup.
