Dryer runs but no heat: what to check (electric + gas)
If the drum spins but clothes stay wet, start with power/airflow, then move to simple heating checks. Avoid unsafe gas DIY.
When a dryer runs but doesn’t heat, the most common culprits are power, airflow, or a failed heating component.
1) Check airflow first
If the vent is clogged, dryers can shut off heat to prevent overheating.

Electric dryers often need two hot legs of power. If one breaker trips, the dryer can still run but won’t heat.
3) Gas dryer: if you smell gas, stop
If you smell gas, turn off the dryer and call your gas utility or a qualified tech.
4) If you’re comfortable with basic diagnostics
Common parts:
- thermal fuse
- thermostat
- heating element (electric)
- igniter (gas)
If you’re not experienced with appliance disassembly, this is a good point to call a pro.
