Possible Causes
Blocked lint filter or condenser, Failed circulation fan, Tripped high-limit thermostat, Restricted exhaust duct
How to Fix / Troubleshooting
Safety first: Unplug the dryer and let it cool fully before inspection.
- Clean filters and condenser: Remove all lint filters and the condenser unit. Clean thoroughly as per Siemens instructions.
- Check exhaust duct (vented models): Ensure the duct is not crushed or blocked and that the external vent is clear.
- Inspect circulation fan: Access the internal fan (usually behind a side or rear panel). Remove lint build-up from the blades and ensure it spins freely. Replace the fan motor if it does not run.
- Reset or replace thermostat: Locate the high-limit thermostat on the heater housing. If it has a reset button, press it. If it is a one-shot fuse and open-circuit, replace it and correct the underlying airflow issue.
