What do refrigerators with ice makers require?

Most icemakers use an electric motor, an electrically operated water valve and an electrical heating unit. To provide power to all these elements, you have to hook the icemaker up to the electrical circuit powering your refrigerator.

Do you have to use the ice maker in a refrigerator?

A water line allows you to make ice in your refrigerator. Refrigerators that feature built-in water dispensers or automatic ice makers need to be connected to a water source. Fridges without ice makers or water dispensers dont need any type of water source to function properly.
