Possible Causes

Clogged lint filter or vent restricting airflow

Part: Lint filter and dryer vent system

Overloading dryer drum reducing airflow

How to Identify: Dryer drum is too full, clothes are tangled together, drying times are long and uneven

Part: Dryer drum load capacity

Faulty heating element or insufficient heat generation

How to Identify: Dryer runs but clothes are not warm or barely warm after a cycle, prolonged drying times

Part: Heating element

Thermostat or thermal fuse issues preventing proper heating

How to Identify: Dryer may start but not reach proper drying temperatures, may shut off unexpectedly or clothes remain damp

Part: Thermostat or thermal cutoff fuse

Moisture sensor malfunction (ventless models)

How to Identify: Dryer ends cycles prematurely because sensor falsely detects dryness, damp clothes remain
