How to Fix / Troubleshooting
Safety first: Unplug the dryer and allow it to cool before working near the heater.
- Check basic settings: Ensure you have not selected an air-only or cool program on your Siemens dryer.
- Clean filters and condenser: Blocked airflow can cause thermostats to trip. Clean all filters and the condenser as per the user manual.
- Access heater assembly: Remove the rear or side panel to reach the heater housing. Inspect for visible damage or broken coils.
- Test heater and thermostats: Use a multimeter to check continuity of the heater and thermostats. Replace any open components.
- Check wiring and relay: Inspect wiring to the heater and the heater relay on the power module for burns or loose connections. Replace the power module if the relay is defective.
