Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: RT18M6215*
What that covers: Samsung top-freezer refrigerator; the freezer sits above the fresh-food compartment and cold air falls into it from there.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — TOP-FREEZER (no through-door dispenser): A top-freezer refrigerator (freezer on top, fridge below) — the simplest, most reliable layout. It has NO through-door water or ice dispenser (top-freezers do not), so any 'dispenser' symptom does not apply to this model; you fill water and take ice from inside.
Ice maker: This model can have a factory automatic ice maker in the top freezer (verified), fed by a water line. If fitted, 'no ice' traces to the water line/valve, the ice maker being switched off, or the freezer temperature; if your unit has no ice maker installed, ice is made in trays instead.
Cooling: A single cooling system with the freezer on top. If the fridge is warm but the freezer is cold, the vent that passes cold air down to the fridge may be blocked by packed food or iced up from a defrost issue — clear the vent and do not overpack the top of the fridge.

Exact questions

Questions that only have an answer for the Samsung RT18M6215 top-freezer refrigerator

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

Where is the water dispenser on my Samsung RT18M6215?+

There isn't one — this is a top-freezer refrigerator, and top-freezers do not have a through-door water or ice dispenser. You take water and ice from inside. If your unit has the factory ice maker in the freezer, ice is made there automatically from a connected water line; otherwise you use ice trays. So dispenser troubleshooting simply does not apply to this model.
