How to fix it

  1. Unplug the dryer before testing.
  2. Locate the outlet (exhaust) control thermistor near the blower/duct outlet.
  3. Inspect its connector and wiring for damage; reseat the plug.
  4. Test the thermistor's resistance against the model's spec (NTC — resistance should drop as temperature rises); replace it if it reads open.
  5. If the sensor and wiring test good, the electronic control board may need replacement.

Why it happens

Typical signs: E71 displayed at start or during a cycle · Dryer may run but temperature control seems off (too hot or too cool) · Cycle may abort

  • Failed or open outlet control thermistor (NTC 1) The sensor near the blower/duct outlet has failed open.
  • Broken wire or loose connector to the thermistor Harness chafe or an unseated plug interrupts the sensor signal.
  • Defective electronic control board Less common than a sensor or wiring fault.
