Follow the manual's cooling and isolation instructions before maintenance. Parts and laundry can remain hot after active heating stops.
Understanding this situation
A filter may have a routine cleaning procedure, but that does not mean every internal area is safe to handle immediately. Opening a lower compartment on a model that contains warm water or components also needs the correct guidance.
A useful next step
Let the dryer reach the specified safe state and clean only permitted parts. Do not rush maintenance because another load is waiting. Report abnormal heat or a burning smell rather than treating it as an ordinary cleaning inconvenience.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
