If your dryer tumbles but does not produce heat, begin with airflow and settings checks. Restricted airflow is one of the most common reasons a dryer performs poorly.
Safe checks to try first
- Confirm that the selected cycle uses heat and is not an air-dry setting.
- Clean the lint filter completely before running another load.
- Check the exterior vent flap while the dryer runs; it should open freely.
- Avoid overloading the drum, which can reduce airflow and drying performance.
- For an electric dryer, check whether a circuit breaker has tripped.
When to call a technician
Stop using the dryer and contact a qualified technician if you smell burning, see damaged wiring, notice sparking, hear unusual electrical noises, or find that the dryer repeatedly overheats.
