No. The cabinet's feel is not a reliable measurement of the programme's internal treatment. Different designs and stages can produce different surface conditions.
Understanding this situation
A warm exterior during drying must be considered against the model's normal instructions, while excessive heat, burning smells or damaged nearby surfaces require a cautious response. Touch alone cannot identify a heater, fan or temperature-control failure.
A useful next step
Use the display, programme result and existing observations in an enquiry. Stop use where there is a safety concern and do not remove panels to measure heat. Avoid holding a hand against an unexpectedly hot surface as a diagnostic test.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
