Clean air mode on the KG hoods runs the blower at first speed for ten minutes every hour. During the run, segments circle around the display; between runs the motor stops and a fixed C stays on the display until the next cycle starts 50 minutes later. Bertazzoni range hood display · also shown as steady C, fixed C What to do when C 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 If you meant to use clean air mode, leave it alone; the hood will keep cycling on its own. ### 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. Clean air mode is started by holding button E for two seconds with the hood off. ## Before you book, in this order. Each step comes from Bertazzoni's own guidance for C on its range hoods. Follow it to the end: the last card says whether this is a visit. 01 If you meant to use clean air mode, leave it alone; the hood will keep cycling on its own. 02 To stop it, press button E (the timer key) again, or press any key other than the light keys to go back to normal use. 03 If the C stays on and the hood never runs again, book a visit for the control board. ### 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 steady C is not the charcoal filter reminder, which flashes and alternates with F. It also does not mean the blower has stalled; the motor is resting between clean air cycles. ## What you may notice with it. The range hood problems C tends to arrive with.

If you meant to use clean air mode, leave it alone; the hood will keep cycling on its own. ### Why does my Bertazzoni hood start up by itself every hour? Clean air mode is on. It runs the blower for ten minutes each hour and shows a steady C in between; press E to switch it off. ### How did clean air mode get turned on on my Bertazzoni KG hood? Holding the timer key E for two seconds with the hood off starts it, so it can happen while wiping the panel. ### Is it safe to leave a Bertazzoni hood in clean air mode? It is a designed function and runs only at low speed. If the hood runs longer than ten minutes at a time, book a visit. --- **[Read on the site: Bertazzoni steady C: clean air mode is running between cycles](https://rangehooderepair.center/error-codes/bertazzoni-c/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
