Enquiry preparation
Cooker hood: describe the last ordinary use
For a cooker hood enquiry: Write down the selected function, the stage reached and the changed result. Separating what you saw from what you suspect makes the first conversation more useful.
Model and requested work checked before an appointment is agreed.

Apply this to your product
Say which fan speeds respond and whether the lights work. A recirculating hood and an externally ducted one have different airflow arrangements.
Why the detail helps
The cooker hood reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Before an appointment is agreed
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
