Enquiry preparation
Oven: agree who can authorise the request
For a oven enquiry: Establish ownership, the person approving work and who can provide entry. Keep those arrangements with the service address so a technical enquiry is not delayed by missing authority.
We agree suitable work and arrangements for your actual appliance.
For the appliance you actually own
A fan, light or clock can work while a selected cooking function fails to heat. Keep the mode symbol, temperature selection and affected cavity together rather than describing the whole oven as dead.
Why this belongs in the enquiry
The oven reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Before arranging a visit
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
