Model overview
On a Cascade hood from La Cornue, the first symptom many owners report is a control that stops responding or a fan that only runs at one speed. Weak suction tends to follow as the unit struggles to move air, and a light that will not come on is often noticed at the same time. Note which of these appears first and whether it happens on every setting. The width on the label, either 36 or 44 inches, is worth confirming. Homeowners in Los Angeles and Orange County should list the Cascade model, the width, and the symptom in their own words in the booking form.
Cascade is a La Cornue 36" or 44" hood. The model number is printed on the rating label, usually inside the hood behind the grease filters; match it letter for letter before booking, because a single letter can change parts.
