Understanding the Problem
Weak airflow from your dryer vent means hot, moist air isn't being properly expelled. You may notice the outside vent flapper barely opens during a cycle. This leads to longer drying times and potential overheating. Common causes include lint buildup in the vent duct, a crushed or kinked vent hose, a clogged lint screen, a worn blower wheel, or a blocked exterior vent hood.

Helpful Repair Tip
Disconnect the vent hose from the dryer and check airflow directly from the dryer blower. If airflow is strong at the dryer but weak at the outside vent, the duct is clogged. Use a vent brush kit to clean it. If airflow is weak even at the dryer, the blower wheel may need replacement.
