Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Longer-than-usual drying times when the vent restricts airflow.
• Reduced airflow at the outdoor exhaust hood.
• Lint or warm air escaping at a loose connection.
• Rattling or movement from an unsecured telescoping section.
• Dryer overheating or cycling abnormally due to restricted exhaust airflow.

Check Before Replacing

• With the dryer off and unplugged, visually inspect the periscope for crushing, kinks, deformation, loose sections, or visible gaps at the connections.
• Check that the telescoping length matches the dryer-to-wall distance without forcing the dryer or sharply bending the vent.
• Inspect the accessible vent openings and exterior exhaust hood for visible lint or blockage; do not disassemble the dryer for this check.
• Confirm that the included clamps are secure and that the vent remains aligned when the dryer is in its operating position.
• During a normal cycle, observe whether airflow is present at the exterior exhaust hood; weak airflow can indicate a restriction elsewhere in the vent system and does not by itself prove this part is defective.
