Known Failure Points
The most common failure types, sorted by when they typically appear.
Exhaust Vent Lint Clog
Lint gradually accumulates inside the exhaust vent duct and at the exterior vent flap. Restricted airflow causes longer dry times, overheating, thermal fuse failures, and in severe cases, dryer fires. The leading cause of residential dryer fires.

⚠️ Safety risk
Warning signs:
Clothes taking longer than usual to dry
Dryer exterior feels unusually hot
Musty or burning smell during operation
Lint visible around the door seal or exterior vent flap
Thermal Fuse Failure
The thermal fuse is a one-time safety device that blows when the dryer overheats, usually from restricted airflow. Once blown, the dryer stops heating or won't start at all. Often indicates an underlying vent or lint buildup problem.

Warning signs:

Clothes take much longer to dry
Dryer shuts off after a few minutes
Burning smell before failure occurred
Heating Element Burnout
The electric heating element coil cycles on and off thousands of times, and the nichrome wire eventually develops a break from thermal fatigue. This is the most common reason an electric dryer stops producing heat entirely.
