What Switches off after 4 hours
actually means.
The Château hood controller shuts the appliance down if no one has pressed a button or used the remote for four hours. It is a safety cut-off so a hood is not left running all day by mistake.

What to do when Switches off after 4 hours shows on the range hoodKind of codeMode, not a failure
The hood is doing something it was told to do, not wearing out: a delay-off timer that keeps the blower running for some minutes after the burners go off, a heat sentry that starts the fan by itself when it senses a hot pan, a Sabbath setting that locks the keys and dims the lights, or a link to the cooking surface that sets the speed on its own. No part is needed; a key sequence from the manual, or simply waiting, ends it.
Usually leads toNo repair
Press the motor button or use the remote to start the hood again.
Shows up asReading a Range Hood Error Code or Blinking Light
A range hood error code may appear as letters and numbers on a display, a light that blinks in a pattern, a filter reminder that will not clear, or a beep with the fan refusing to start.

Before you book,
in this order.
Each step comes from La Cornue's own guidance for Switches off after 4 hours on its range hoods. Follow it to the end: the last card says whether this is a visit.
Press the motor button or use the remote to start the hood again.
If you need longer running, touch any control now and then to restart the four-hour count.
If the hood shuts off after minutes rather than hours, book a visit to check the controller and blower.
Cleared?
The code is gone and the blower pulls steam up on every speed again without a new part. If it returns this week, or the filter reminder keeps coming back right after a cleaning, mention it in the booking.
What not to do
This automatic switch-off does not mean the blower overheated or the controller has failed. A hood that will not come back on at all, even from the buttons, is more likely the red reset switch behind the filters or the supply.

Still showing Switches off after 4 hours?
Three things make the booking useful: the letters or blink pattern exactly as they showed, the full model number from the label behind the filters, and whether the fan still moves air on every speed. With those, the technician arrives with half the answer already worked out.
