--- title: "Bertazzoni blinking 4: intensive speed on a KG hood" description: "What 4 means on Bertazzoni blinking 4: intensive speed on a KG hoods, what to check before booking, and when it is not a failure at all." url: "https://rangehooderepair.center/error-codes/bertazzoni-4/" --- # Bertazzoni blinking 4: intensive speed on a KG hood The fourth speed on a KG hood is the intensive setting. ## What 4 actually means. The fourth speed on a KG hood is the intensive setting. While it runs, the 4 blinks on the display, and after six minutes the blower returns to speed 3 by itself. Bertazzoni range hood display · also shown as blinking 4, 4 flashing What to do when 4 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 it to finish; it drops back to speed 3 after six 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 Bertazzoni A Bertazzoni range hood that has stopped pulling steam is inspected in your kitchen, beginning with the rating label hidden behind its grease filters. ### Source Bertazzoni KG30X 30-inch wall hood user and installation manual Bertazzoni KG30X, KG36X and KG48X wall hoods. The 15-minute shut-off timer cannot run while intensive speed is on. ## Before you book, in this order. Each step comes from Bertazzoni's own guidance for 4 on its range hoods. Follow it to the end: the last card says whether this is a visit. 01 Leave it to finish; it drops back to speed 3 after six minutes. 02 Press the speed key again to move on through the speeds if you want less air sooner. 03 If the 4 blinks and the blower does not get louder, book a visit to check the blower and its capacitor. ### 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 4 is not an alarm; it is how the hood shows that the high setting is on a timer. A 4 that drops to 3 by itself after six minutes is normal and not a sign of overheating. ## What you may notice with it. The range hood problems 4 tends to arrive with.

Leave it to finish; it drops back to speed 3 after six minutes. ### Why won't the timer start on my Bertazzoni KG hood? The 15-minute timer is blocked while intensive speed is on. Wait for the 4 to stop blinking, or step down a speed, then press the timer key. ### Why does my Bertazzoni drop from 4 to 3 during cooking? Intensive speed is timed at six minutes and then returns to speed 3. Press the speed key again to restart it. ### Is a blinking 4 on a Bertazzoni hood a problem with the display? No. The blink is intentional and marks the timed speed. --- **[Read on the site: Bertazzoni blinking 4: intensive speed on a KG hood](https://rangehooderepair.center/error-codes/bertazzoni-4/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
