An appliance problem starting right after a house move, a new detergent or additive, or a water/gas/power supply change should be checked against that specific change first. 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

ReversibleNote exactly what changed — installation, supply type or product used — and confirm it worked immediately before. 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. Test with the previous product or a factory-recommended one, or verify the new supply connection matches the appliance's requirements. 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 installation, switch back to a compatible product, or arrange service for a supply mismatch that cannot be user-corrected.
Verify and stop safely
ReversibleRun one complete normal cycle under the new conditions and confirm normal results. Stop heated use for weak airflow, excessive heat, burning odor or blocked vent.
