Quick answer: stop, unplug, and sort the smell by type
- Scorched dust or toast: lint on the heating element or in the vent.
- Rubber: a slipping or worn belt, or a stuck roller.
- Hot metal: an overheated part, or a coin or key near the heat.
- Electrical or melting plastic: wiring, a terminal block or a wrapper. Stay away and call.
- Smoke: close the door, ventilate the room and see the stop list below.
- Gas: leave the home and call 911 and your gas utility.
Why a dryer smells like burning: the causes, ranked from most to least common
Lint on the element or in the vent: the dryer lint fire smell
The most common cause is lint. It collects near the heating element and in a blocked vent. It can scorch or smolder. Loads that take longer to dry are often the first hint. Both Mr. Appliance and Asurion rank lint first. Asurion cites NFPA's finding. Failure to clean is the leading cause of dryer fires.
Dryer burning rubber smell: the belt, pulley or rollers
A worn belt can slip and melt from friction. That is why a dryer burning rubber smell points to the belt. In gas dryers it can also touch hot parts. A stuck roller or idler pulley makes friction heat too. It often squeals or thumps as well. If the smell comes with a new noise, stop using the dryer.
Hot metal: objects and overheating
Coins, keys, crayons and wrappers can fall past the drum. They land near the heating element, where they melt or burn. Overloading cuts airflow and raises heat. A failing thermostat can let the dryer run too hot. Hot metal with no lint and no belt sign points here.
Wiring and the motor
A loose terminal block or heating element terminal can overheat and smell electrical. Appliance Parts Pros says household wiring, outlets and the breaker panel belong to an electrician. A tired motor adds a warm, oily smell. Leave both to a technician.
A brand-new dryer
Factory oils and coatings burn off in the first cycles. Sources differ on the break-in: Mr. Appliance says low heat for 15 to 20 minutes. Appliance Parts Pros says high heat for 20 to 30 minutes. Follow your manual, ventilate and stay nearby.
Safe checks for a dryer burning smell before you run another load
- Unplug the dryer. For a gas dryer, close the gas valve. Let it cool.
- Remove the clothes and empty the lint screen.
- Look through the drum with a flashlight for coins, keys and wrappers.
- Vacuum around the lint screen housing and behind the dryer.
- Pull the dryer forward and check that the vent hose is not crushed or kinked.
- Go outside and check that the vent flap opens and is not packed with lint.
- Reconnect the dryer and run a short test cycle with dry towels, staying in the room.
Opening the cabinet to test a thermostat, belt or wiring is a technician job. Skip it unless you have the model's service sheet and a meter.
When to stop the dryer and call a technician
- Smoke that lasts or thickens. Keep the door closed, ventilate and call 911. Mr. Appliance says to call if smoke is heavy or lasts more than 5 minutes.
- The smell returns after you cleaned the screen and vent.
- A burning smell together with squealing, grinding or thumping.
- A cabinet that is very hot to the touch.
- An electrical odor, melted plastic or discolored plug or outlet.
- A gas smell. Leave the home first, then call 911 and your gas utility from outside.
Do not restart a dryer that smoked. CPSC also says not to leave dried clothes sitting in the dryer, because they can ignite after drying.
What a technician checks, and when a repair makes sense
A technician unplugs the machine first. Then they check vent airflow, the heating element, thermal fuse and thermostats. They also check the belt, idler pulley, rollers, motor and wiring terminals. A belt, roller set or thermostat is a normal repair on a dryer in good shape. On an old machine, a scorched drum or damaged wiring is where replacement starts to be the smarter call. We will say so before you pay.
Prevention: clean the screen every load and the vent on a schedule
Empty the lint screen every load and avoid overloading. Replace plastic or foil duct with rigid metal duct, as CPSC advises. A clogged vent is the common thread. See dryer vent lint removal for the full run. See dryer repair if the smell points to a worn part.

CPSC warns that lint buildup overheats dryers, and that dried clothes can ignite later
CPSC Publication 5022 explains how an overheated dryer starts a fire. Lint builds up in the dryer or exhaust duct, and heat has nowhere to go. A damp load after a normal cycle can mean a blocked screen or duct. So can drying that takes longer than usual.
CPSC tells owners to clean the lint screen before or after each load. It says to clean the duct periodically and to replace foil or plastic duct with metal. Not to leave dried clothes in the dryer or in a basket. A careful technician checks those same things first. A burning smell with a blocked vent is a warning, not a mystery. The lesson: treat a scorched smell as a stop sign.

Questions Las Cruces households ask after a burning smell
Is a burning smell from the dryer dangerous?
Yes, treat it as a warning. A burning smell means something is scorching. It is most often lint near the heat, a worn belt or an object. Stop the dryer, unplug it and let it cool. Do not run another load until you have cleaned the screen and vent. Find the cause first.
Why does my new dryer smell like it is burning?
New dryers can give off a smell as factory oils and coatings burn off the heating element. Sources differ on the break-in cycle, so follow your manual. Ventilate the room and stay nearby. If the smell lasts past a few cycles, or smoke appears, stop and call.
Why does my dryer smell like smoke when nothing is on fire?
If your dryer smells like smoke, something is scorching or smoldering out of sight. Lint on the heating element, a melted object or a hot belt can all do it. Unplug the dryer now and check for glowing lint or visible smoke. If there is any flame or heavy smoke, leave and call 911.
Can a clogged vent cause a burning smell?
Yes. A clogged vent traps heat. The dryer runs hotter and lint can scorch. Mr. Appliance lists a blocked lint trap, vent hose or outside vent cover among the causes. Check the outside flap while the dryer runs. If it barely lifts, the vent needs cleaning.
What should I do if my dryer starts smoking?
Turn the dryer off and unplug it. Keep the door closed so less oxygen reaches the heat. Open windows and doors to clear the room. Call 911 if smoke is heavy or does not stop quickly. Do not restart the dryer after smoke. Do not open it until it cools.
Is it safe to use the dryer again after the smell goes away?
Only after you find the cause. If cleaning the screen and vent removed the smell, run a short test with dry towels. Stay in the room. If the smell returns even once, stop using it and call. A smell that fades is not the same as a fixed dryer.
