Possible Causes

Clogged lint filter reducing airflow

Incorrect drying cycle/settings

How to Identify: Use of ‘Air Dry’ or non‑heated cycles on loads needing heat

Part: Control/Settings

Blocked or restricted external vent/ducting

How to Identify: Airflow weak at exhaust vent outlet; significant lint/debris seen

Part: Vent hose/external vent

Faulty heating element or heater assembly

How to Identify: Drying produces little to no heat

Part: Heating element

Faulty temperature sensor/thermostat

How to Identify: Dryer cycles but heat shuts off prematurely or incorrectly

Part: Thermistor/thermostat
