Why is my dryer running but not heating?
Dryer tumbles but clothes stay wet? A clogged vent is the most common cause. Here's the full troubleshooting guide.
Most common causes
- 01Clogged dryer vent (most common — restricts airflow required for heating)
- 02Blown thermal fuse (one-time-use safety device)
- 03Failed heating element (electric)
- 04Failed gas igniter or gas valve solenoid (gas)
- 05Tripped high-limit thermostat
What to do right now
1
Check that the dryer vent is not kinked, crushed, or clogged at the exterior exhaust point2
Clean the lint trap fully3
For electric: check that both breaker legs are on (dryers use 240V — a partial trip cuts heat but not the motor)When to call a professional
Call if: vent is clear but dryer still won't heat, the thermal fuse has blown (requires disassembly to replace), or clothes are still damp after 2 full cycles.
