Safe first steps

  1. Unplug the dryer from the power outlet to ensure safety before inspecting the temperature sensor.
  2. Locate the temperature sensor at the compressor outlet, which is usually found near the back of the dryer.
  3. Check the wiring and connections to the temperature sensor for any visible damage or loose connections.
  4. If the wiring appears intact but the error persists, consider replacing the temperature sensor as it may be faulty.
  5. 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.
