Because a Samsung ice maker is a sub-assembly built into a refrigerator rather than a product sold on its own, it has no model prefix or plate of its own — it is identified entirely by the host refrigerator’s number. That means an ice-maker repair is planned from an RF, RS, RT, or RB model such as the French-door RF28R7351SR or the side-by-side RS28CB760012.
Samsung has fitted several distinct ice-maker designs across those refrigerators over the years: a single in-door icemaker, a freezer-mounted maker, a Dual Auto Ice Maker that adds a second bin, and higher-tier units that also produce cubed or specialty ice. Which one you have is encoded in the host refrigerator’s characters — the capacity class, generation, and feature tier — and confirmed by the finish suffix. The rating plate carrying that full model and serial number is on a side wall inside the fresh-food compartment, so it is worth reading before ordering any part. The host refrigerator’s serial number, printed on the same plate, dates the build and narrows down which ice-maker revision was fitted, since Samsung phased new harvest and auger designs in mid-production on several models.
That complete string is what actually determines which auger motor, fill valve, harvest module, or full ice-maker kit fits, because those assemblies are not interchangeable between designs even within one body style. Note the host refrigerator’s model and serial, plus whether the icemaker sits in the door, the fresh-food section, or the freezer, before you book ice maker repair for a clear, upfront quote, and the right part can be on the truck for the first visit.
