Enquiry preparation
Oven: keep the complete product reference
For a oven enquiry: Use existing paperwork or a safely visible label. Copy suffixes, service numbers and variant endings as well as the name. The badge on the front is a starting point, not the full identity.
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.
