What is an ice maker? Well, that’s pretty obvious, but how do these brilliant machines work? Let’s take a look at the science behind these household appliances that most of us couldn’t live without.
You might think that making ice is modern technology, but our ancestors had it figured out as early as 400 B.C. with the use of yakhchāls, an ingenious way to create and store ice in the middle of the desert. Throughout the ages, people learned how to "harvest" the ice during the winter months (does the movie Frozen come to mind?) and store it underground for months to come.
It wasn’t until the 1800s when the idea of artificial refrigeration and ice making came about, with several inventors racing to create the best prototypes. Some attribute the success to American physician John Gorrie, who created a refrigerator to treat yellow fever patients. Others credit Frederic Tudor, aka the Boston Ice King, and still others say it was Alexander Twining, who was awarded the U.S. Patent for the icemaker in 1845.
Understanding the Refrigeration Process
This model from Southwest Wisconsin Technical College shows how the basic refrigeration cycle works.
The four main components of a refrigeration system include the evaporator, compressor, condenser, and expansion valve.
This process allows a unit to mechanically remove warm air from one place and exchange it with cooler air to create a cooler or icebox.

People Also Ask (FAQs)
Can water filters cause the ice maker not to work?
Yes, a clogged water filter can prevent your ice maker from creating ice. This is one of the reasons these filters must be changed every six months.
Why did my ice maker stop working? What causes an ice maker to stop working?
Common reasons your ice maker stops working include a clogged filter, a frozen/clogged water line, a mechanical malfunction, and the thermostat being set too low.
Will my ice maker work without a filter?
Some ice makers have a bypass plug on their waterline, that will allow the ice maker to function and water to flow without a filter being in place. Check your user guide to see if this applies to your ice maker.
How long do these ice machines last?
On average, you can expect your refrigerator ice maker to last 10-18 years. Commercial ice machines that are used every day will last 5-10 years, and portable ice machines for personal use will vary depending on usage, but you can usually expect them to be productive for at least 5 years.
