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. La Cornue range hood display · also shown as automatic switch-off What to do when Switches off after 4 hours shows on the range hood ### Kind of code Mode, 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 to No repair Press the motor button or use the remote to start the hood again. ### Shows up as Reading 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. ### Make La Cornue A La Cornue hood is serviced with care for its finish, and the technician protects the metal and the burners below before work begins. ### Source La Cornue Château range hood installation and user guide (110-120V 60Hz models) La Cornue Château wall hoods, Château Suprême hoods and LCHI island hoods on 110-120V, 60Hz. ## Before you book, in this order.

Follow it to the end: the last card says whether this is a visit. 01 Press the motor button or use the remote to start the hood again. 02 If you need longer running, touch any control now and then to restart the four-hour count. 03 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.

Press the motor button or use the remote to start the hood again. ### Why did my La Cornue hood stop during a long braise? If no one touched it for four hours, the controller switched it off. Start it again from the panel or the remote. ### Can the four-hour switch-off be turned off on a La Cornue hood? The guide describes no setting to disable it; touching a control resets the four hours. ### My La Cornue hood will not restart. Is this the same thing? No. After the four-hour stop the buttons still work; if they do not, check the red reset switch behind the filters, then book a visit. --- **[Read on the site: La Cornue hood off by itself: the Château four-hour switch-off](https://rangehooderepair.center/error-codes/la-cornue-4-hour-off/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
