Samsung ranges split by fuel in the model prefix: NE marks an electric range such as the NE63T8511SS, and NX marks a gas or dual-fuel range such as the NX60T8511SS. Both slide-in and freestanding versions exist, and Bespoke models add changeable colors and a Smart Dial control that adapts to your most-used settings.
The characters after the prefix encode oven capacity (the “63” and “60” track roughly to a cubic-foot class), the generation, the feature tier, and a finish suffix like SS for stainless. Flex Duo models divide the oven into two independently controlled cavities with a Smart Divider, so one range can run two temperatures at once; Air Fry, Air Sous Vide, a griddle-ready center burner, and a steam-assisted clean appear across the higher tiers. The rating plate carrying the full model and serial number is usually on the frame behind or beneath the storage drawer, or along the edge of the oven door, so it is easy to reach without moving the range. The serial number on that plate dates the build, and pairing it with the model tells a technician which relay board or gas-valve revision your range uses, since Samsung updated those parts across a single model’s run.
Confirming electric versus gas, single versus dual cavity, and slide-in versus freestanding from that model number tells a technician whether a repair points at an igniter and gas valve or a bake element, relay, and control board. And because Samsung revises those internals across model years within the same prefix, the complete model-and-serial string is what pins down the exact compatible part. Record it before you book range repair for a clear, upfront quote.
