Understanding the Problem
When your dryer runs much longer than expected on an auto dry cycle, it may be unable to properly sense that clothes are dry, or the heating may be insufficient to dry clothes in normal time. Common causes include dirty or faulty moisture sensors, restricted airflow from a clogged vent, a failing heating element, or a faulty thermistor.

Helpful Repair Tip
Start by cleaning the exhaust vent — restricted airflow is the most common cause of extended drying times. Also clean the moisture sensor bars with rubbing alcohol. If both are clean and the dryer still runs too long, check the heating element — it may be partially burned out, producing less heat than normal.
