Enquiry preparation
Oven: record the product identity
For a oven enquiry: Copy the full reference from existing paperwork or a safely visible label. Include the variant ending and any product or service code instead of relying on the front badge.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Record the cavity, temperature setting and mode that was in use. A lit display or running fan can coexist with a heating problem on a particular function.
How this supports the discussion
The oven reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Confirm the proposed attendance
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
