Your dryer's temperature sensor isn't reading correctly
Moderate
What to do
Why this happens
Potential causes include restricted airflow due to a clogged case filter leading to abnormal temperature readings, thermistor 1 having resistance out of range (open or shorted), or issues with thermistor wiring such as damage or disconnection.
How to fix it
Clean the lint screen and check that your exhaust vent isn't blocked or kinked. If that doesn't fix it, the temperature sensor likely needs replacing — a technician can handle that.
