Cooker hood · Focused observation
A sound has changed
Explain whether the sound starts immediately or at a later stage, using words such as buzz, scrape, tap or rattle. Burning, smoke or uncontrolled movement mean stopping use, not making a demonstration.
We agree suitable work and arrangements for your actual appliance.

How this relates to your cooker hood
Explain whether the fan responds at each normal setting, whether the lights respond and whether the hood recirculates air or has an outside duct.
Describe the observation before its possible cause
Describe what you saw during ordinary use, then retain the complete model. An observation can help frame an assessment but does not establish which part is faulty.
Leave unsafe behaviour undemonstrated
Do not repeat a cycle to recreate smoke, tripping, burning, unsafe movement or leakage near electrical parts. Keep connected equipment in place and do not remove covers.
