The blower runs at speed one for ten minutes every hour for a full day while T1 flashes; with the remote, the display shows 24. Bertazzoni range hood display · also shown as T1 LED blinking, 24 What to do when T1 flashing 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 want the kitchen aired through the day, leave it on. ### 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 KMC30X 30-inch canopy hood installation, use and care manual Bertazzoni KMC30X, KMC36X and KMC48X canopy hoods. ## Before you book, in this order.

If you want the kitchen aired through the day, leave it on. ### Why does my Bertazzoni hood run for ten minutes at a time with no one cooking? The 24-hour air circulation mode is on. Hold T1 for two seconds to end it. ### What does 24 on my Bertazzoni hood mean? When started from the remote, the 24-hour mode shows 24 on the display while it cycles. ### Does 24-hour mode stop by itself on a Bertazzoni? Yes, after a 24-hour cycle. --- **[Read on the site: Bertazzoni T1 flashing: 24-hour air circulation on a KMC hood](https://rangehooderepair.center/error-codes/bertazzoni-t1-flashing/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
