The control may sit beneath parts of a dual-fuel appliance. Access requirements are separate from the electrical nature of the replacement component.
What the observation means
A photograph of a broken knob does not establish whether a cover can be removed without disturbing gas-related parts. The exact construction matters.
A useful next step
Tell the booking team the cooker is dual fuel and describe the proposed work. Let them confirm competence and scope. Do not remove the hob cover or disconnect pipework yourself to make an apparently electrical job easier.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
