Quick Answer
If your dryer smells burnt, stop the cycle, unplug the dryer or turn it off at the breaker if safe, clean the lint screen, check for lint around the door opening, and do not restart the dryer until you know the smell is not coming from overheating, wiring, a motor, a belt, a heating element, or blocked venting. A slight hot smell after a new dryer installation or after long disuse may clear quickly, but a strong burning odor, smoke, electrical smell, repeated overheating, scorching, or a dryer that gets too hot needs professional dryer repair.

Repair Difficulty Meter
Easy homeowner checks: cleaning the lint screen, removing visible lint from the door opening, checking that clothing is not overloaded, confirming the dryer is not pushed tightly against the wall, and making sure the exterior vent flap opens.
Moderate homeowner checks: checking the flexible vent hose for kinks, confirming airflow outside during a short no-heat or air-fluff test if safe, and cleaning accessible vent sections without crushing or disconnecting hidden parts.
Professional repair recommended: electrical odor, smoke, scorch marks, repeated overheating, burning rubber smell, drum not turning, loud squealing, breaker trips, damaged power cord, gas odor, or any inspection requiring cabinet disassembly.
