What is Automatic Defrost?

Automatic defrost, also known as auto-defrost, is a common feature on a refrigerator or freezer that heats the coils inside the appliance regularly. This component keeps frost build-up from forming on the inside of your freezer or refrigerator. Unlike freezers and refrigerators with manual defrost, self-defrosting appliances operate on a regular cycle that defrosts the cooling coils automatically. While you'll find automatic defrost in most fridges, there are many deep freezers that have manual defrost instead.

Benefits of Automatic Defrost

  • Prevents heavy frost build-up in freezers and refrigerators

  • Avoids the need for manually defrosting your refrigerator
