(Introduction – Urgency & Safety)
A burning smell from your dryer is a serious warning sign that should never be ignored. It could indicate a fire hazard. Immediately turn off and unplug the dryer, and remove any clothes inside. This guide will help you identify the cause of the smell and determine the next steps.
What’s That Smell? Identifying the Source
Pinpointing the type of burning smell is the first step in troubleshooting.
Lint: The Usual Suspect
The most common cause is lint buildup. Lint is highly flammable. A burning lint smell, often accompanied by longer drying times and excessive lint on clothes, suggests a clogged lint trap, vent hose, or both.
Action:
- Clean the Lint Trap: Remove and thoroughly clean the lint trap after every load. Scrub away any residue with soap and water if needed.
- Check the Lint Trap Housing: Lint can also accumulate inside the lint trap housing. Vacuum this area regularly.
- Inspect and Clean the Vent Hose: Detach the vent hose from both the dryer and the wall outlet. Use a brush, vacuum, or dryer vent cleaning kit to remove lint buildup. Check for kinks, bends, or damage and replace if necessary. Rigid metal or semi-rigid metal ducting is recommended.
- Examine the Exterior Vent: Ensure the exterior vent flap opens and closes freely. Remove any blockages like bird nests or debris.
Rubber: A Worn Belt
If the smell resembles burning rubber, a worn or loose dryer belt is the likely culprit. The friction from a slipping belt generates heat and that distinct odor.
Action:
- Inspect the Belt: Consult your dryer’s manual for instructions on accessing the drive belt. Look for cracks, fraying, or excessive wear.
- Replace the Belt (DIY or Pro): Replacing a dryer belt is often a manageable DIY project. Numerous online tutorials can guide you through the process. However, if you’re not comfortable with this repair, contact a qualified appliance repair technician.
Plastic: Melting Components
A burning plastic smell suggests a melting plastic component within the dryer. This could be a melted blower wheel, pulley, or other plastic part.
Action:
- Consult a Professional: This is beyond a simple DIY fix. Contact a qualified appliance repair technician to diagnose and resolve the issue.
Electrical: A Serious Hazard
An acrid, electrical burning smell signals a potential electrical problem, such as a faulty thermostat, heating element, or damaged wiring. This is extremely dangerous and requires professional expertise.
Action:
- Call a Qualified Electrician: Do not attempt to repair electrical components yourself. Contact a licensed electrician immediately.
Gas: An Immediate Threat (Gas Dryers Only)
If you have a gas dryer and smell a burning odor accompanied by a sulfurous or rotten egg smell, it could be a gas leak. This is an extremely dangerous situation requiring immediate action.
Action:
- Turn off the Gas Supply: Locate the gas shutoff valve for the dryer and turn it off.
- Evacuate: Leave your home immediately.
- Contact the Gas Company or a Qualified Technician: Do not attempt to find the leak yourself. Contact your gas company or a qualified gas appliance technician as soon as possible.

Preventing Dryer Fires: Proactive Steps
Regular maintenance is the best defense against dryer fires.
- Clean the Lint Trap After Every Load: This simple habit makes a big difference.
- Inspect and Clean the Vent Hose Every 3-6 Months: Use a brush, vacuum, or cleaning kit to remove lint buildup.
- Avoid Overloading the Dryer: Overloading restricts airflow and can lead to overheating.
- Don’t Dry Items with Flammable Substances: Gasoline, paint thinner, and cleaning solvents should never be put in the dryer.
- Check Your Pockets: Remove all items from pockets before drying clothes to prevent foreign objects from entering the dryer.
When to Call a Pro: Don’t Risk It
While many dryer issues are easily solved with DIY fixes, some require professional attention. If you’ve tried the troubleshooting steps and the burning smell persists, or if you’re unsure about any aspect of the repair, it’s always best to call a qualified appliance repair technician. Don’t risk your safety or the safety of your home. A professional can properly diagnose and resolve the problem, ensuring your dryer operates safely and efficiently.
Further Considerations
- New Dryer Smell: A slight odor from a brand-new dryer is usually temporary and dissipates after a few cycles.
