An appliance that fails partway through a cycle and sometimes completes normally usually points to a specific stage — fill, wash, spin, heat or dry — not total failure. For dryer exhaust airflow, first run briefly and compare airflow/temperature at the exterior with the duct inspected.
What this covers
- dryer exhaust airflow with this exact failure state
- Diagnosis across lint screen/internal path versus transition duct, wall vent and exterior hood

0 of 4 completedCapture the exact failure state
ReversibleNote exactly which stage the cycle stops or errors at, and whether it's the same stage each time. Expected behavior: move heated moist air through the full vent to the exterior.
Isolate the component boundary
ReversibleRun briefly and compare airflow/temperature at the exterior with the duct inspected. Run the specific stage in isolation where the appliance allows it, and repeat with a different, similar-sized load. Boundary to separate: lint screen/internal path versus transition duct, wall vent and exterior hood.
Correct only the proven cause
ReversibleClean the full path and correct crushed, long or unsafe ducting. Correct the loading, supply or setting proven to affect that one stage, or arrange service for a component fault confirmed at that stage.
Verify and stop safely
ReversibleRun two complete normal cycles in a row and confirm the same stage no longer fails. Stop heated use for weak airflow, excessive heat, burning odor or blocked vent.
