The space can contain hot surfaces, sharp edges and concealed gas or electrical connections. Reaching blindly is different from using an accessible normal isolator.
What the observation means
An unfamiliar lead may not belong to the function you intend to stop. Moving the cooker to gain access adds further risks.
A useful next step
Use the safely accessible control identified for the appliance, or obtain appropriate help if isolation is unclear. Tell the service team about inaccessible connections. Do not pull cables by their cords or open fixed electrical fittings to discover where the cooker is supplied.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
