What to do
Why this happens
Causes may include a clogged lint screen restricting airflow, a restricted vent system leading to abnormal temperature readings, or Thermistor1 resistance being out of range due to an open or shorted condition.
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.
