Dryer Running But Not Heating
Diagnose why your dryer runs but clothes remain wet.
Troubleshooting Steps
Check Heat Settings
Verify the dryer is not set to Air Dry or No Heat cycle. Select a heated dry cycle.
Clean the Lint Filter
A clogged lint filter restricts airflow and reduces heating efficiency. Clean before every load.
Inspect the Vent System
Disconnect the vent hose and check for lint buildup. Clean the entire vent path from dryer to outside.
Test Outside Vent Flap
Go outside and verify the vent flap opens when dryer runs. A stuck flap restricts airflow dramatically.
Check Power Supply (Electric)
Electric dryers need 240V power. A partial power loss from a tripped breaker allows running but not heating.
Verify Gas Supply (Gas Dryers)
Ensure gas valve is fully open. Check if other gas appliances work. Smell for gas but do not proceed if you smell a leak.
Check Heating Element/Igniter
Electric dryers: Element may be visible through back panel. Gas dryers: Igniter should glow during heating.
When to Call a Professional
- Heating element is visibly broken
- Gas igniter does not glow
- Thermal fuse has blown (dryer will not heat at all)
- Motor runs but drum does not turn
- Vent is clear but heating is still inadequate
