Samsung’s refrigerator lineup splits by body style in the model prefix: RF for French-door models such as the RF28R7351SR, RS for side-by-side models such as the RS28CB760012, RT for top-freezer models, and RB for bottom-freezer models. Family Hub versions layer a touchscreen and interior cameras onto many RF models.
The characters after the prefix encode capacity (the “28” tracks roughly to a 28 cubic-foot class), the generation, the feature tier, and a finish suffix like SR for stainless. Bespoke models add flat or beveled changeable door panels in several colors; Twin Cooling Plus keeps the fresh-food and freezer sections on independent evaporators; and a FlexZone convertible drawer, a Beverage Center with an AutoFill water pitcher, and a Dual Auto Ice Maker appear across the higher tiers. The rating plate carrying the full model and serial number is on a side wall inside the fresh-food compartment, usually near the top or on the lower left. The serial number printed beside it dates the build, and on a refrigerator that detail is especially valuable because sealed-system and inverter parts were changed several times within a single model’s production run; reading both together avoids ordering a board or compressor that fits an earlier or later batch.
Recording that full string matters more here than on almost any other appliance, because Samsung has changed compressors, evaporators, ice-maker assemblies, and control-board revisions across model years within the same body style — the ice maker and sealed-system parts in particular vary widely, so the prefix alone is never enough to plan a repair. Note the complete model and serial before you book refrigerator repair for a clear, upfront quote, and the correct part can be matched to your exact unit.
