If your dryer smells like burning, stop the cycle, unplug it, and keep the door closed. The usual causes are lint on the heating element or burner, a worn belt, an overheating motor or a foreign object. If you smell gas, leave the house and call 911 and Atmos Energy at 866.322.8667.
Key takeaways
- Stop the dryer and unplug it, or switch off the breaker, before anything else.
- A smell of gas is different: leave the house, then call 911 and Atmos Energy.
- Lint on the heating element or burner is the most common cause, and a fire risk.
- Do not run the dryer again until you have found the source.
What to do in the first five minutes
- Stop the dryer. Press stop and open nothing if you see smoke or flames.
- Cut the power. Unplug the dryer or switch off its breaker.
- Smoke or flames? Keep the door closed, leave the house and call 911.
- Smell gas? Do not touch switches. Leave the house, then call 911 and Atmos Energy at 866.322.8667 from a safe distance.
- Air the room out and do not restart the dryer until you know the cause.
Which smell is it?
The type of smell points to the source. If you are not sure whether it is gas, treat it as gas.
| Smell | Likely source | What to do |
|---|---|---|
| Rotten eggs or sulfur | A gas leak at a gas dryer or its supply line | Leave, avoid switches, call 911 and Atmos Energy |
| Hot dust or scorched lint | Lint cooking on the heating element or burner, often from a blocked vent | Stop, unplug, clear the lint screen and vent, have it tested |
| Burning rubber | A slipping belt, seized idler pulley or hard-to-turn drum | Stop, see the noisy dryer guide |
| Sharp, chemical or hot plastic | Overheating wiring, terminal block, cord connection or motor | Stop, switch off the breaker, have it inspected |
| Faint hot smell on a new dryer | Manufacturing residue burning off the heater | Should fade within a few loads; stop if it is strong |
| Musty or damp | Moisture or mildew in the drum or vent (not burning) | Clean the drum, run the vent test |
How do I tell a gas smell from a burning smell?
Natural gas has an added rotten-egg odor and lingers in the air near the dryer or gas line, while a burning smell is hot, dusty, rubbery or electrical and comes from the drum. If you are unsure, treat it as gas: leave the house and call 911 and Atmos Energy at 866.322.8667.
Lint on the heating element or burner
Lint is fine, dry fuel. When airflow is restricted, the dryer runs hotter and lint can scorch against the heating element or the burner. You may smell hot dust, see the lint screen packed, or find the thermal fuse blown. This is the most common cause, and it is how many dryer fires begin.
Can lint really start a dryer fire?
Yes. Lint is dry, fine fuel, and when airflow is blocked the dryer runs hotter and lint can ignite on the heating element or burner. NFPA data list failure to clean as the leading cause of dryer fires, at 31 percent of cases.
A worn belt or seized pulley
A burning-rubber smell usually means friction. A glazed or slipping belt, or an idler pulley that has seized, can get hot enough to smell. You will often hear squealing too.
Why does my dryer smell like burning rubber?
Burning rubber usually means friction on the belt: a slipping or worn belt, a seized idler pulley, or a drum that is hard to turn. You may also hear squealing. Stop using the dryer, because a failing belt can overheat and snap. See the noisy dryer guide for how to tell which part it is.
An overheating motor or electrical problem
A hot, sharp or chemical smell can come from the motor, the terminal block or a connection at the cord. Overheating wiring can melt insulation long before anything catches fire, which is why the smell matters. Outlet and breaker problems belong to a licensed electrician.
Why does my dryer smell like burning plastic?
A hot plastic or chemical smell may come from wiring, the terminal block, the power cord connection or the motor overheating, or from plastic or a lighter left in a pocket. Switch off the breaker, unplug the dryer, and have it inspected before using it again.
An object in the drum or heater box
A crayon, lighter, plastic or a pen that slipped out of a pocket can melt and smell. Check the drum and the lint trap area once the dryer has cooled.
If you see smoke or flames
Smoke is different from a smell. If you see smoke coming from the dryer or the vent, or any flame, treat it as a fire.
- Do not open the dryer door if you see flames: opening it feeds the fire.
- If it is safe to reach, switch off the dryer’s breaker or unplug it. Do not keep trying to deal with it.
- Get everyone, including pets, out of the home, and call 911 from outside.
- Do not use the dryer again until a professional has checked it.
Steam at the outside vent on a cold day is normal. Smoke inside the home, a burning smell with it, or scorched lint is not.
What should I do if my dryer is smoking?
Treat it as a fire. Do not open the door if there are flames. If it is safe, switch off the breaker or unplug the dryer, then get everyone outside and call 911. Do not use the dryer again until it has been checked, and never ignore smoke inside the home.
When your clothes come out smelling burnt
A burnt smell on the laundry, with the dryer itself seeming fine, usually has a simple cause. But a burnt smell with a very hot dryer or a long cycle points to overheating.
| Likely cause | What to do |
|---|---|
| Heat too high for the fabric, such as synthetics | Use a lower heat setting and a shorter cycle |
| Fabric softener or detergent film baked onto the drum or sensor | Wipe the drum and the moisture sensor bars, with the dryer unplugged |
| Lint or residue near the heater or burner | Clean the lint screen and the lint housing |
| A restricted vent making the dryer overheat | Run the 10-minute vent test: vent safety guide |
| Oil, food or other spills on the clothes | Rewash before drying: heat can set the odor |
| A smoky odor already in the laundry, such as from cooking or a fire | Rewash before drying, because heat can lock odors in |
Why do my clothes smell burnt after the dryer?
Often the heat is too high for the fabric, or softener film or lint has built up. A restricted vent can also overheat the dryer and scorch loads. Lower the heat, clean the lint screen and the drum, and run the vent test. If the dryer itself smells hot, stop using it.
A gas dryer that smells like burning
A gas dryer can smell of burning for the same reasons as an electric one, plus the burner. A faint smell of dust or lint burning off in the first cycles after it has sat unused is common. A smell that persists, a yellow or sooty flame, or any smell of rotten eggs is not. The rotten-egg smell is the gas odorant: leave the house and call 911 and Atmos Energy at 866.322.8667.
See what to do if you smell gas near a dryer and the flame sensor and burner page.
Why does my gas dryer smell like burning?
Usually lint or dust near the burner, a restricted vent that makes it overheat, or a foreign object. A faint dust smell in the first cycles can pass. A rotten-egg smell is gas, so leave and call 911 and your gas utility. A yellow or sooty flame means stop and call a technician.
When it smells hot, but not quite burnt
A warm, laundry-like smell is normal. A sharp, hot smell, like a hair dryer on high, means the dryer is running hotter than it should. The usual cause is restricted airflow: a lint-packed vent or housing, a crushed duct, or a blocked outside hood. Heat that cannot escape cooks the parts, so treat it as a warning, not just an odor. See the vent cleaning page.
Why does my dryer smell hot?
A sharp hot smell means the dryer is running hotter than it should, almost always from restricted airflow. Lint in the vent or housing, a crushed duct or a blocked hood traps the heat. Stop the dryer, let it cool, run the 10-minute vent test, and have the vent cleared before you use it again.
When to call 911 and when to call a pro
- Flames or smoke: keep the door closed, leave the house and call 911.
- Smell of gas: leave the house, then call 911 and Atmos Energy at 866.322.8667.
- Burning smell, no flames: stop, unplug, and call a technician before using the dryer again.
Is a burning smell from a dryer dangerous?
It can be. A burning smell can mean lint is scorching near the heater, a belt is slipping, or wiring is overheating, and each can lead to a fire if you keep running the dryer. Stop the dryer, unplug it, and do not use it again until the cause is found.
How to prevent a burning smell
- Empty the lint screen after every load and wash it a couple of times a year
- Run the ten-minute vent test every few months
- Have the full vent run checked about once a year
- Do not run the dryer while you are out or asleep
- Keep the area around the dryer clear of clothes, boxes and chemicals

Frequently asked questions
What should I do if my dryer smells like burning but there is no smoke?
Stop the cycle, unplug the dryer or switch off its breaker, and leave the door closed for a few minutes. Open a window, check the lint screen, and feel the outside vent. Do not restart the dryer until you know the cause. If you are unsure, have a technician inspect it.
Why does my dryer smell like burning when it is new?
A new or newly repaired dryer can give off a faint hot smell as manufacturing oils or dust burn off the heater in the first few cycles. It should fade within a few loads. If the smell is strong, gets worse, or comes with smoke, stop and call.
Is it safe to use the dryer after the smell goes away?
Not until you know why it happened. A burning smell that stops after you shut the dryer off is still a sign of overheating, lint buildup or friction. Clear the lint screen and vent, run the ten-minute vent test, and have the dryer checked if you cannot find a cause.
Why does my dryer smell like smoke or hot dust?
A smoke or hot-dust smell usually means lint is cooking against the heating element or burner, often because the vent is blocked. It is a fire warning. Stop the dryer, clear the lint screen and duct, and have the heating parts and thermostats tested before the next cycle.
Can a burning smell damage the dryer?
Yes. The same overheating that causes the smell can blow the thermal fuse, warp plastic parts, damage the heating element or burn out the motor. Stopping early usually means a cheaper repair. The cost guide lists typical repair ranges.
Does a burning smell always mean a fire risk?
Not always, since a brief new-dryer smell or a forgotten item in the drum can be harmless, but you cannot tell by smell alone. Treat every burning smell as a warning until you have found the source, and call 911 at once if you see smoke or flames.
What should I do if my dryer is smoking?
Treat it as a fire. If there are flames, do not open the door. If it is safe, switch off the breaker or unplug the dryer, then get everyone out and call 911.
Why does my gas dryer smell like burning?
Usually lint or dust near the burner or a restricted vent. A rotten-egg smell is gas: leave the house and call 911 and your gas utility.
Why does my dryer smell hot?
A sharp hot smell means the dryer is running hotter than it should, usually from restricted airflow. Stop it, let it cool, and check the vent.
Why do my clothes smell burnt after drying?
The heat may be too high for the fabric, or softener film or lint has built up. A restricted vent can also scorch loads, so check the vent.
