The CornuFé 90 and 110 Hoods are controlled by a remote and an activation cover, drive a 4-speed motor, and light the cooking area with three 20W halogen lamps — details published on La Cornue’s own technical sheets for these hoods, and useful to know because they point directly at where a problem most likely sits.
Fan Not Responding to a Speed Setting
Before assuming the motor has failed, check whether the remote itself is responding — a remote that has lost its pairing, or has a depleted battery, produces exactly the same sign from the user’s side as a dead motor: nothing happens when a speed is selected. Confirming whether the activation cover and remote are working correctly is a fast first step that rules out a large share of “the fan won’t turn on” calls without opening anything.
Lights Out or Flickering
With three separate 20W halogen lamps on the CornuFé hoods, one lamp failing is the most common lighting complaint, and it is worth checking whether all three are affected or just one before assuming a wiring problem. All three lamps failing together, or flickering together, points more toward the lighting circuit or its connection than toward the lamps themselves, since three separate bulbs failing at once is far less likely than a shared circuit issue.
Why the Housing Matters for This Repair
The light circuit on any La Cornue hood sits inside a housing that also collects grease over time, which is exactly why lighting work is a job for a technician with the power isolated rather than something to reach into casually while the range below is in use — grease and an open electrical connection are not a combination to work around informally.
The Fan Speed Itself, Once the Remote Is Ruled Out
If the remote and activation cover are confirmed working and the fan still will not respond, or responds only on certain speeds, the motor’s speed control circuit is checked next. A fan that runs on some speeds but not others points at that control circuit specifically, rather than at the motor failing outright, since a fully failed motor would not run at any speed at all.
The Château Hood’s Similar Layout
The Château Hood, matched to the Château range in size and finish, uses the same general category of motor, filter and lighting layout as the CornuFé hoods, even though La Cornue publishes fewer standardized specifications for it given its wider range of custom sizes and finishes. The same diagnostic order — remote and lamps first, then the speed control circuit, then the motor itself — applies regardless of which hood is fitted.
If your hood’s lights or fan are not responding as expected, a La Cornue range hood repair visit checks the remote, the lamps and the speed control circuit, with the power isolated, before concluding the motor has failed.
