Enquiry preparation
Oven: clarify what the proposed work includes
For a oven enquiry: Ask about labour, parts and possible further attendance before agreeing the request. A symptom guide cannot establish a component order, stock position or final charge.
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.
