Washer-dryer door glass becomes excessively hot during drying.

How to Fix / Troubleshooting

Safety first: Unplug the appliance and allow it to cool before inspection.

Step-by-step checks:

Clean airflow components: Ensure condenser, ducts, and any lint filters are clean.
Check load size: Do not exceed the recommended drying load (often half the wash capacity). Overloading restricts airflow.
Inspect door seal: Ensure the door gasket is intact and correctly seated, so air flows as designed.
Test thermostats: Verify dryer thermostats and NTC are functioning correctly; replace if they allow excessive temperature.

When to call a technician: If the door remains dangerously hot despite cleaning and correct loading, professional diagnosis is needed.
