No. Covering a running dryer can obstruct required openings and retain heat. It does not address the source of a new sound.
Understanding this situation
An external vibration and an internal scrape need different assessment, but neither is solved safely by wrapping the cabinet. Stored textiles should remain clear of the appliance's specified ventilation and access areas.
A useful next step
Stop use if the noise is concerning and record its stage. Keep the surrounding arrangement according to the manual. Do not add weight, tape or acoustic packing around a hot appliance to suppress the symptom.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
