Possible Causes

Root causes behind this error

• Faulty thermal sensor (thermistor) unable to read temperature accurately • Thermal cutoff switch has tripped due to overheating or blockage • Broken or disconnected temperature sensor wiring or connector • Lint buildup restricting airflow causing false thermal sensor readings • Damaged heating element preventing proper temperature regulation • Control board failure preventing communication with temperature sensor • 240V power supply issue affecting sensor circuit on USA models • Moisture ingress in sensor connector causing electrical malfunction

Safety Checks You Can Do

Steps you can try at home safely

• Check that your dryer is properly plugged into a grounded 240V outlet (USA standard) • Verify the circuit breaker for your dryer has not tripped; reset if necessary by switching off and back on • Ensure the dryer door is fully closed and latching completely • Remove and clean the lint trap thoroughly with a lint brush • Inspect the external vent hood on the back of your home for blockages or lint accumulation • Verify the vent duct is not kinked, crushed, or clogged with lint • Check that dryer control panel settings are correctly selected for your desired cycle • Allow the dryer to cool for 15-20 minutes, then attempt the cycle again • Reset the dryer by switching the circuit breaker off for 60 seconds, then turn back on • Test with a short drying cycle (15 minutes) to see if error clears • Ensure proper ventilation space around the dryer for adequate airflow
