Refrigerator Ice Maker Types Compared

Standard crescent ice makers produce the familiar half-moon ice cubes at a rate of 4-6 pounds per day. They are reliable, easy to repair, and fit in any freezer. The downside is the cube shape (not great for cocktails) and the relatively slow production speed during a hot summer party.

Gourmet ice makers (sometimes called clear ice or specialty ice) produce larger, slower-melting cubes by freezing water from the outside in, which clears it of dissolved gases and produces visually striking ice. They work in a separate compartment with their own water line and produce about 2 pounds per day. They are common on premium refrigerators and freestanding ice makers from Sub-Zero, Scotsman, and similar brands.

Nugget ice (sometimes called Sonic ice or pellet ice) is the chewable, soft, porous ice that absorbs flavor from the drink. It is produced by a different mechanism — water is frozen into thin sheets that are then scraped, compressed, and extruded into pellets. Nugget ice makers are common as standalone countertop or under-counter units (Opal, GE Profile, Scotsman); some premium refrigerators now integrate a nugget maker alongside a standard cube maker.

Dual ice makers (one in the freezer, one in the door) are a feature of premium French-door refrigerators. The freezer ice maker handles bulk production; the door ice maker is a smaller faster unit that produces fresh cubes for the dispenser. The combined output (10-15 lbs/day) handles entertaining loads that would overwhelm a single-unit refrigerator. The trade-off is two ice makers to maintain and two failure points; budget accordingly.
