Holding High for 3 seconds switches the QuietBoost blower to its Boost speed for a heavy burst of smoke or steam. The High LED blinks while Boost is on, and after 15 minutes the hood returns to normal speed. Boost is louder than High, which is expected. Café range hood display · also shown as Boost What to do when High button LED blinking 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 Leave Boost to finish if the kitchen is smoky; it ends after 15 minutes. ### 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 Café Cafe range hoods whose lamps flicker or whose fan will not change speed are checked in place, working from the switch back to the blower. ### Source Café vented range hoods with QuietBoost blower owner's manual 49-2000706 (CVW9304, CVW9364) Café commercial hoods CVW9304 and CVW9364 (owner's manual 49-2000706); the CVW7301/CVW7361 glass canopy hoods run Boost for 10 minutes after a 2-second hold on Hi. ## Before you book, in this order. Each step comes from Café's own guidance for High button LED blinking on its range hoods. Follow it to the end: the last card says whether this is a visit. 01 Leave Boost to finish if the kitchen is smoky; it ends after 15 minutes. 02 If you want to end it early, press Power to switch the fan off. 03 If the High LED blinks without Boost being chosen, or the blower does not speed up when it blinks, book a visit. ### 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 A blinking High LED is not a warning about the motor. If the fan instead keeps stopping and starting on its own, that is overheating, which Café links to the motor and dirty filters. ## What you may notice with it.

Leave Boost to finish if the kitchen is smoky; it ends after 15 minutes. ### Why is my Café hood so loud with the High light blinking? It is on Boost, the strongest speed, which runs for 15 minutes. It settles back once Boost ends. ### How do I turn on Boost on a Café commercial hood? Hold the High button for 3 seconds. The High LED starts blinking to show Boost is on. ### Is it bad to use Boost often on my Café hood? Boost is there for heavy cooking and times itself out. If the fan starts cutting out on its own, clean the filters and book a visit if it continues. --- **[Read on the site: Café commercial hood: only the High light is blinking](https://rangehooderepair.center/error-codes/cafe-high-led-blinking/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
