Safe first steps
- Unplug the dryer from the power outlet to ensure safety before inspecting the temperature sensor.
- Locate the temperature sensor at the compressor outlet, which is usually found near the back of the dryer.
- Check the wiring and connections to the temperature sensor for any visible damage or loose connections.
- If the wiring appears intact but the error persists, consider replacing the temperature sensor as it may be faulty.
- If the temperature sensor is visibly damaged or the error continues after replacement, arrange a service visit — do not run the appliance.
When to stop
- Stop if you see any burnt marks or smell burning near the temperature sensor — risk of fire.
