Direct answer
For the Samsung RT18M6215 top-freezer refrigerator, prove the outlet, breaker/GFCI and control/display modes before internal service. First, test the outlet safely and reset the correct breaker once.
What this covers
- Samsung RT18M6215 top-freezer refrigerator (RT18M6215*)
- Samsung top-freezer refrigerator; the freezer sits above the fresh-food compartment and cold air falls into it from there.
- The specific fault this record addresses: has no power
What it does not cover
- ×The same symptom on a different Samsung product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The plug has worked loose or the outlet has failed
What separates it Nothing at all from the unit. Vibration over time can walk a plug partly out of an outlet that is never inspected because it is behind the appliance.
How to confirm Pull the unit out enough to see the outlet, reseat the plug firmly, and test the outlet with a known-good device.
- 2
A GFCI outlet has tripped
What separates it No power, and the breaker panel shows nothing wrong. A tripped GFCI does not register at the panel.
How to confirm Look for a reset button on the outlet itself or on an upstream outlet on the same circuit — often in a garage or bathroom.
- 3
The breaker has tripped
What separates it No power, with other devices on the same circuit also dead.
How to confirm Reset it once. A breaker that trips again immediately points at a short rather than a nuisance trip.
- 4
Demo mode or a display-off setting is masking normal operation
What separates it The unit appears not to run but the lights work, or the display is blank while cooling continues.
How to confirm See not-cooling and lights-display. This is not a power problem at all.
- 5
The control board or compressor start relay has failed
What separates it Confirmed live outlet and nothing from the unit, or a repeated clicking every few minutes with no cooling.
How to confirm This is the conclusion once supply is proven, and is a service repair.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether anything at all responds — lights, display, or any sound.
- Whether the outlet is GFCI-protected, and whether its reset has tripped.
- Whether the plug is fully seated, checked by actually looking at it rather than assuming.
- Whether a repeated click occurs every few minutes, which points at the start relay.

ReversibleDiagnosis takes time and food safety does not wait for it.
Pull the unit out and confirm the plug is fully seated
ReversibleVibration can walk a plug partly out of an outlet nobody ever looks at.
Check for a tripped GFCI on the outlet or upstream on the same circuit
ReversibleA tripped GFCI shows nothing at the breaker panel, so it is easy to miss entirely.
Reset the breaker once
ReversibleDo not repeatedly reset a breaker that trips again immediately.
Test the outlet with a known-good device

Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- RT18M6215*. Samsung top-freezer refrigerator; the freezer sits above the fresh-food compartment and cold air falls into it from there.
- 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.
- Symptom boundary
- This record covers Samsung RT18M6215 top-freezer refrigerator when it has no power. A different symptom on the same hardware, or this symptom on a different Samsung product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Discard food that has been above 40°F for more than about two hours.
- !Unplug and stop for a hot plug, scorch marks at the outlet, arcing, a burning odour, or a breaker that trips again as soon as it is reset.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Samsung Support publishes this as "Samsung washing machine information and error codes". Samsung's own washer troubleshooting and error-code article; covers filling, draining, spin and unbalanced-load conditions. What that article does not carry is the model boundary — it is written for a product line, and RT18M6215* is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
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.
My refrigerator is completely dead but the breaker looks fine.+
Check for a GFCI outlet — a tripped GFCI shows nothing at all at the breaker panel, so it gets overlooked constantly. The reset button may be on the outlet behind the refrigerator or on an upstream outlet on the same circuit, often in a garage or bathroom. After that, pull the unit out and confirm the plug is actually fully seated; vibration can walk it partly out of an outlet nobody ever inspects.
Does this answer apply to every Samsung model?+
No. It is scoped to RT18M6215*. Samsung top-freezer refrigerator; the freezer sits above the fresh-food compartment and cold air falls into it from there.
What should I record before troubleshooting no power or dead fridge?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing no power, dead fridge. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Unplug for heat, arcing, cord damage or repeated trips.
