Enquiry preparation
Cooker hood: make a short sequence of events
For a cooker hood enquiry: Describe selection, operation and outcome in that order. Add anything that still responds normally, keeping your observation separate from a suggested failed component.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Explain whether the fan responds at each normal setting, whether the lights respond and whether the hood recirculates air or has an outside duct.
How this supports the discussion
The cooker hood 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.
