No. A timer changes when the programme begins, not the need to follow attendance and safety guidance. Delayed operation while everyone sleeps can reduce the chance of noticing a fault promptly.
Understanding this situation
The feature should be used within the manufacturer's instructions and a sensible household schedule. Cheaper electricity or a desired morning finish does not remove the hazard from unattended heating.
A useful next step
Choose an attended period and review the load before starting. Do not use remote or delayed controls to run a known faulty dryer. If the required timing is unsuitable, use an appropriate alternative drying arrangement.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
