Possible Causes
Failed dryer NTC sensor, Loose or damaged NTC wiring, Overheated dryer duct causing sensor damage, Faulty control board input
How to Fix / Troubleshooting
Safety first: Unplug the appliance and allow the dryer section to cool completely.
- Locate dryer NTC: The dryer NTC is typically mounted on the dryer air duct or heater housing. Remove the top or rear panel to access it.
- Inspect and reseat connector: Check the NTC plug for secure fit and clean contacts. Reseat firmly.
- Test NTC (qualified persons): Measure resistance at room temperature and compare to the specified value in Blomberg documentation. Replace the sensor if readings are out of range or unstable.
- Check airflow: Clean lint from ducts and filters to prevent overheating, which can damage sensors.
- Control board diagnosis: If E15 persists with a known-good NTC and wiring, the main PCB may be faulty and should be checked by a professional.
