GE Profile Opal Mini Nugget Ice Maker (P4NM20KZLG)

The Opal Mini is for the person who wants nugget ice but has run out of counter. It is the small-counter pick on our nugget ice maker list: at 8.6 inches wide it is the narrowest machine we compared, and at 14.56 inches tall it sits well under the typical 18-inch gap below upper cabinets, though you should check that the top-fill lid has room to open. It suits one or two people who want a glass of nugget ice through the day.

It is not the machine for a household that fills pitchers or throws parties. The bin holds 2 pounds and there is no side tank on the base model, so it refills its bin and needs water more often than bigger machines.

Size. GE says the Mini is about 30 percent smaller than the Opal Ultra, two inches shorter and two inches narrower, and 25 percent lighter. The spec sheet lists 8.6 inches wide, 15.6 deep and 14.56 tall, with a net weight of 27 pounds. For comparison, the Opal 2.0 Ultra with its side tank measures 13.43 inches wide and weighs almost 38 pounds. GE still asks for 4 inches of air at the sides and back, so budget about 16.6 inches of width in practice.

Top fill. The Mini drops the Opal's side tank in favor of a reservoir you fill from the top. On the full-size Opal without a tank, refilling means sliding out the bin to reach the reservoir; here you lift a lid. GE's launch release leads with this change, and The Gadgeteer lists it among the Mini's main features.

Cleaning access. The front panel flips open to reach the parts that need cleaning and descaling, and GE says water drains from the key areas so none stays trapped inside. The clean cycle runs 3 minutes, and the Mini takes the same filters as the bigger Opals: a taste-and-odor filter or a scale-inhibiting filter, each rated for three months, though it runs without one. GE's general Opal cleaning guidance still applies: sanitize weekly and descale on a schedule set by your water hardness, from every few months with soft water to every few weeks with hard.

Output. GE rates the Mini at 1.5 pounds an hour and up to 36 pounds a day, close to the 38 pounds of the full-size Opal, and its spec table puts first ice at 5 minutes with 60°F water in a 70°F room. The Gadgeteer's summary of the launch quotes a more conservative 10 minutes. Built-in Wi-Fi connects it to GE's SmartHQ app.

Bin and water. The 2-pound bin is a third smaller than the Ultra's, and the reservoir is split into 0.5 liters upper and 2 liters lower. That is fine for steady personal use but means frequent refills if you run it hard. The Mini Pro and Pro+ add a side tank, but they widen the machine to 11.6 inches, which undoes much of the reason to buy a Mini.

Unproven. GE made the Mini available on July 14, 2026. At the time of writing we found spec summaries and launch coverage, including The Home Picker's model-by-model breakdown, but no long-term independent testing, so claims about ice texture and reliability rest on GE's word and the Opal line's history. The Home Picker also points out that GE's own figures differ between variants: the Mini lists 36 pounds a day, the Pro+ spec table 34.

Controls and noise. The Mini uses mechanical push buttons with four status lights (defrosting, clean, add water and making ice) rather than the Ultra's touch display. GE lists it at 45 dBA, similar to the Ultra's 44 and higher than the GoveeLife's claimed 40 dB. The warranty is one year on parts.

Against the Opal 2.0 Ultra, the Mini gives up a pound of bin space, the side tank, the touch display and the Ultra's bundled scale-inhibiting filter, and gains nearly five inches of width and about 10 pounds. Choose the Ultra if you have the room; choose the Mini if you do not.

Against the Frigidaire Gallery EFIC255, which sits in a similar entry price class, the Frigidaire has a 3-pound basket and a higher 44-pound rating but is 10.6 inches wide, lacks Wi-Fi and has firmer pellets in Reviewed's testing. The Mini is the better fit for a narrow space and for fans of the Opal's texture.

The GE Profile Opal Mini is the easiest nugget ice maker to fit into a small kitchen, and it brings the top-fill reservoir and front cleaning access that the full-size Opal lacks. Buy it for one or two people and a tight counter. If you need more ice at once or rarely want to refill, the full-size Opal or the GoveeLife is the better tool, and it is worth watching for independent long-term reviews as the Mini ages.
