Protection behaviour varies between appliances, so do not rely on a stopped motor remaining stopped. Put the operating control off and follow the model's isolation guidance before any approved maintenance.
What the observation tells you
Some protection arrangements need a manual reset; others can behave differently. Waiting until the casing feels cooler is not proof that power is disconnected or the cause of a stall has gone. Do not place fingers or tools in the chamber while waiting.
A useful next step
Identify the full model and consult its instructions before considering a restart. An unexplained stop, especially with a smell or repeated protection event, needs professional assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
