Possible Causes
Faulty NTC temperature sensor, Stuck heater relay, Incorrect program selection, Blocked airflow causing localized overheating
How to Fix / Troubleshooting
Safety first: Unplug the dryer before testing sensors.
- Verify settings: Ensure you are using the correct program and low heat options for delicate fabrics.
- Clean filters and condenser: Restricted airflow can cause hot spots. Clean all air paths.
- Test NTC sensor: Measure the resistance of the drum/exhaust NTC at room temperature and compare to specs. Replace if out of range.
- Check heater relay: If the heater remains on when it should cycle off, the control board relay may be stuck. Replace the main control board.
- Monitor temperature: Use a thermometer at the exhaust (if accessible) to verify that temperatures match program expectations.
