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.

2) Electric dryer: check the outlet/breaker

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.
