Enquiry preparation
Oven: put the last use into a short sequence
For a oven enquiry: Write the selected function, what changed and the result in that order. Include the exact warning and anything that still responds. This communicates an observation without naming a guessed component.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
The cavity, cooking mode and temperature belong together in an oven enquiry. Lights, the clock or a fan may still respond when one heating function does not. Describe the affected mode without assuming the whole oven has failed.
The purpose of this detail
The oven reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
What still needs agreement
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
