An appliance that will not run a cycle at all should be separated into power/door-safety interlocks, the selected cycle's own requirements and the specific component before assuming a major 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
What it does not cover
Try in this order
0 of 4 completedCapture the exact failure state
ReversibleCheck whether the appliance powers on at all, whether the door or lid shows as fully closed and locked, and whether an error code displays. 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. Try the simplest normal cycle with a light or empty load, keeping the door/lid and power connection unchanged. 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. Fully close and re-latch the door, clear the specific error code's documented cause, or restore power at the breaker.
Verify and stop safely
ReversibleRun one complete normal cycle and confirm it finishes without re-triggering the fault. Stop heated use for weak airflow, excessive heat, burning odor or blocked vent.
