If you have a refrigerator with an ice maker, the process to make the ice takes around 90 minutes. The ice cube mold within the ice maker is filled with water where the ice freezes into cubes. Once the freezing process is complete, the ice cubes are dispensed from the ice mold about an hour and a half later.  Note that if you have a brand new refrigerator, you’re probably going to want to throw out the first batch of ice so as to not ingest any impurities that might be in the water line.
