# Samsung range: Demo mode

### What the appliance is actually reporting

Demo mode lets a range light up and respond on a shop floor without heating anything. On a range in a kitchen it produces a very specific and very confusing symptom: everything works, nothing gets hot. Gas cooktops will still ignite, which makes it more confusing still, because the top is clearly alive while the oven does nothing. Turning it off is model-specific and is in the manual.

### The other light combinations that mean this

tESt · tE5t

Samsung publishes forty light combinations for the dishwasher alone, and several of them mean the same thing. They are grouped here by what they mean rather than made into forty near-identical pages, and every combination the maker names is printed above.

### Where this appears, and why not to clear it

On the cycle lights, on a machine with no digital display. Samsung publishes what each combination means, and on those models the combination is the entire diagnosis — it disappears the moment the power is cut. Write it down or photograph the panel before switching anything off. Samsung adds one caution of its own and it saves service calls: on some models the lights blink to show cycle status, so treat it as an error only if the machine is misbehaving as well.

### What to do about it

- Confirm the display is showing tESt or tE5t rather than a code.
- Look up the demo mode procedure for your model; it differs across the range.
- If the oven heats normally after demo mode is off, nothing was ever wrong.
- If you have a range that will not heat, check this before anything else on this site.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 506-1256](tel:+13055061256) and describe what the panel is doing before booking anything.
