Do this first
Stop the cycle and switch the machine off at the breaker if you smell burning, if the cord or receptacle is hot, or if the duct connection has softened or discoloured. Do not run another load to see whether it repeats. Nothing on this page is a repair you should attempt; the owner part is isolation and clearing lint.
The conditions that belong here
- A burnt or scorched smell during or after a cycle — Lint in contact with something hot. It does not need to be visible to be real.
- The plug, cord or receptacle is warm or hot to the touch — A connection that cannot carry the load, and it degrades in one direction only.
- The breaker trips when the machine calls for heat — A load-dependent fault, most often at the heater or the cord rather than in the electronics.
- The flexible duct has melted, sagged or discoloured — Heat where heat should not be, and evidence of a restriction that has already happened.
- A gas smell near a gas cabinet — The one condition on this page with an instruction that comes before any diagnosis.
- NEAR MISS: the machine simply runs cold — That is a heating failure and it belongs on its own page unless something also smells or trips.
What sits behind them
- Lint accumulated in the duct, the chute or the cabinet — First, because it is present in every one of these machines and it is what turns a small fault into a fire. It is also the only one an owner can remove.
- A degraded cord, plug or receptacle connection — Second. High current through a loose joint makes heat, the heat damages the contact, and the damage increases the heat.
- A failed heater shorting to the cabinet — Third. It explains a breaker that trips only when heat is called, and it is not visible from outside.
- A gas connection leak on a gas cabinet — Last by frequency and first by urgency, which is why this page is not ordered by likelihood alone.
What to do, in urgency order
- Evacuate first if you smell gas, then call from outside — Nothing else here matters while a gas smell is unresolved.
- Switch the machine off at the breaker and leave it off — Isolation is the action that changes the situation; diagnosis can wait.
- Do not run another load to reproduce the fault — Reproducing a thermal fault is the one test that can make the situation worse.
- Clear lint from everywhere you can safely reach — It removes the fuel, and it is the only hazard reduction an owner can perform.
The owner actions that make sense
- Switch the dryer off at the breaker and leave the door open to cool — An open door lets the cabinet cool and lets you smell whether the odour is still developing.
About 10 min
- Look at the plug and receptacle for discolouration or melting — Look only. Heat marks at a receptacle are an electrical call rather than a dryer call.
Tools: flashlightAbout 10 min
- Remove and inspect the whole flexible duct — Softening, sagging or a brown patch tells you where the heat has been concentrating.
Tools: vacuumAbout 20 min
- Clear lint from the screen slot and as far into the chute as you can reach — This is fuel removal, and it is worth doing before the appliance is used again.
Tools: vacuum, narrow nozzleAbout 20 min
- STOP: do not open the cabinet to look for the source — Behind the panel there are live terminals and a heater, and this page is not a repair guide.
The non-negotiables
Safety
Unplug the appliance or switch off its breaker before removing any panel, and remember that a capacitor can hold a charge after the power is off. If you smell gas, do not switch anything on or off, leave the building, and call the gas utility or your local emergency number from outside; do not look for the leak yourself. Never run a dryer with the duct disconnected, and never vent one into the room: the lint and moisture it carries are exactly what the duct exists to remove.
Always a call
Every condition on this page needs a technician, and a hot cord or receptacle needs an electrician rather than an appliance technician. A gas smell is a utility call first. Leave the breaker off until somebody has looked, and say plainly what you smelled, what you touched and what was running, because those three answers decide who should come and how quickly.

What is deliberately absent
This covers the Samsung dryer class and carries no wiring colours, terminal-block layouts or part references, because nothing here is an owner repair and those details differ by family and fuel type. Where a family or model page exists it names the arrangement for that cabinet and is the right reference for whoever services it.
