Compare dryer codes that usually point to restricted airflow, long dry time, lint, vent, or overheating warnings.
Use this as a narrowing step
A symptom can point to several different parts or installation issues. Use this hub to find likely code records, then confirm the exact code on the appliance display.

How to narrow it
Stop the dryer and note whether the alert appears with longer drying, a temperature warning, or a specific airflow message. Check only the lint screen and externally accessible vent outlet after the appliance is off and cool; do not open panels or run repeated tests. Airflow and temperature records overlap in visible symptoms, so match the complete code first. A returning warning, burning smell, smoke, or unusual heat needs a service boundary.
