Main Difference
The main difference between Freezer and Icebox is that the Freezer is a household appliance for preserving frozen food and Icebox is a non-mechanical household appliance for cooling foodstuffs
Icebox
An icebox (also called a cold closet) is a compact non-mechanical refrigerator which was a common early-twentieth-century kitchen appliance before the development of safely powered refrigeration devices. Before the development of electric refrigerators, iceboxes were referred to by the public as “refrigerators”. Only after the invention of the modern day electric refrigerator did the early non electric refrigerators become known as an icebox. The terms ice box and refrigerator were used interchangeably in advertising as long ago as 1848.
