Turbo is the fourth speed on Smeg's touch panels. While it runs, its key flashes, and after about seven minutes the motor steps down to speed 3. Smeg range hood display · also shown as speed 4 What to do when Turbo key 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 Use Turbo for heavy steam or smoke and expect the step down. ### 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 Smeg A Smeg hood with a fan that won't start or lamps that won't light is seen in your kitchen, and the visit begins at its switch. ### Source Smeg user interface guide for touch-panel hoods (KBTU) Smeg KBTU and KPRU touch-panel hoods (guides 91477B656 and 91477A860). ## Before you book, in this order.
