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
Condenser and Heat Exchanger Clog
Heat pump dryers have an internal condenser and heat exchanger that accumulates lint and dust over time. Unlike exhaust vent clogs in conventional dryers, this buildup reduces the heat pump's efficiency and can trigger error codes or automatic shutoff.

Warning signs:
Drying cycles take progressively longer
Condenser filter indicator light comes on
Dryer stops mid-cycle with error code
Reduced airflow felt at the door opening
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.
