Possible Causes

How to Fix / Troubleshooting
Safety: Unplug the dryer and allow it to cool completely.
- Check airflow: Clean the lint filter, inspect the exhaust duct for kinks or blockages, and verify strong airflow at the outside vent hood.
- Clean internal lint: Remove the front panel and blower housing cover (if accessible) and vacuum lint buildup around the blower and ductwork.
- Inspect thermistor: Locate the thermistor on the blower or exhaust duct. Check for secure mounting and intact wiring.
- Test thermistor: Measure resistance at room temperature and compare to Samsung specs. Replace if out of range.
- Reset and test: After cleaning and any part replacement, restore power and run a timed dry cycle to confirm normal operation.
