Clean air mode switches the KPH blower on at first speed for ten minutes every hour. While it runs, the F and C keys flash together; between runs the blower stops and the F key stays lit steadily until the next cycle. Bertazzoni range hood display · also shown as F key steady What to do when F and C keys 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 hourly airing, leave the hood as it is. ### 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 KPH36XT 36-inch wall hood user and installation manual Bertazzoni KPH36XT, KPH48XT, KPH362XT and KPH482XT wall hoods.

Each step comes from Bertazzoni's own guidance for F and C keys flashing on its range hoods. Follow it to the end: the last card says whether this is a visit. 01 If you want the hourly airing, leave the hood as it is. 02 To stop it, press key B, or press a speed key to go straight back to normal use. 03 If the keys flash and the blower does not run at all, book a visit to check the blower and 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 The flashing pair is not a filter reminder; on the KPH hoods that job belongs to the A key. It is also not a stuck keypad, since any key other than the light key ends the mode. ## What you may notice with it. The range hood problems F and C keys flashing tends to arrive with.

If you want the hourly airing, leave the hood as it is. ### Why does my Bertazzoni KPH hood run for ten minutes every hour? Clean air mode is on. Press B to switch it off. ### Why is the F key lit on my Bertazzoni hood when the fan is off? Between clean air cycles the F key stays lit to show the mode is still active. ### Can clean air mode run all night on a Bertazzoni? It keeps cycling until someone cancels it, at first speed only. If the blower runs non-stop instead, book a visit. --- **[Read on the site: Bertazzoni F and C keys flashing: clean air mode on a KPH hood](https://rangehooderepair.center/error-codes/bertazzoni-f-c-keys/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
