Dryer stops mid-cycle and displays E2, may feel excessively hot inside drum

Safety first: Disconnect power before inspection. Surfaces may be hot—allow the dryer to cool.

• 1. Clean airflow path: Remove and thoroughly clean the lint filter. Inspect and clean the internal lint duct, blower housing, and the full length of the exhaust hose and wall vent. Remove any lint buildup or obstructions.
• 2. Check vent installation: Ensure the vent hose is not crushed, kinked, or excessively long. Use rigid or semi-rigid ducting where possible.
• 3. Inspect thermistor: Access the exhaust thermistor on the exhaust duct. Check for lint coating the sensor; gently clean with a soft brush. Inspect wiring for damage.
• 4. Test thermistor: With a multimeter, verify resistance at room temperature and compare to service specs. Replace if out of range.
• 5. Heater control check: If airflow is good and thermistor is OK, the heater relay on the main control may be sticking closed, causing overheating. This requires control board testing and likely replacement by a technician.
• 6. Reset and test: After cleaning and any part replacement, restore power and run a timed dry cycle while monitoring temperature and airflow at the vent.
