Dryer smells like burning

Symptoms

• Hot, dusty, or burning odor during or after a cycle
• Smell strongest near the back or bottom of the dryer
• Possible faint smoke
• Smell fades after the dryer cools but returns each use

Likely causes

• CommonLint accumulation near the heating element or motorTrapped lint can scorch when it contacts hot components, producing a burning smell without visible fire.
• PossibleWorn or slipping drive beltA belt rubbing against a pulley or drum edge can produce a rubbery burning smell.
• PossibleForeign object melting against the heating elementA stray piece of plastic or rubber from clothing can melt onto hot parts.
• PossibleOverheating motor bearingA failing motor can produce an electrical or hot-metal smell along with the burning odor.
• Less commonElectrical wiring or connection issueLoose or damaged wiring can overheat and produce an acrid electrical smell, which is more serious.

What to do

1. Stop the dryer immediately and unplug it if you smell burning, especially if it's acrid or electrical rather than dusty.
2. Let the dryer cool completely before opening any panels.
3. Check the lint filter and lint trap housing for buildup, and clean thoroughly.
4. Look inside the drum for any melted plastic, rubber, or foreign objects.
5. Open the back or front panel if you're comfortable to check for lint buildup around the motor and heating element (unplug first).
6. Do not run the dryer again if you smell anything electrical or see scorch marks or melted wiring insulation.
7. Have a technician inspect the belt, motor, and internal wiring before resuming normal use.
