Faber lets installers limit a hood's airflow for local rules. After the under-395 adjustment the intensive speed no longer works; after the under-295 adjustment speed three and intensive stop too. Faber says the change cannot be reversed, and a label is put inside the hood behind the filters. Faber range hood display · also shown as under 295 CFM, under 395 CFM, T3 and T4 same speed What to do when Top speeds disabled after CFM adjustment 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 Look behind the grease filters for the under 295 or under 395 CFM label. ### 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 Faber A Faber range hood that runs on only one speed, or hums without spinning, gets a visit that starts at its speed control. ### Source Faber Inca Lux Premium insert installation, use and care guide Inca Lux Premium insert with the 4-button control; other Faber models with 295-395-600 CFM options follow a similar scheme in their own manuals. ## Before you book, in this order. Each step comes from Faber's own guidance for Top speeds disabled after CFM adjustment on its range hoods. Follow it to the end: the last card says whether this is a visit. 01 Look behind the grease filters for the under 295 or under 395 CFM label. 02 If it is there, the buttons are working as set and no repair is needed. 03 If there is no label and the higher speeds still do nothing, book a visit to test the blower and the keypad. ### 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 Dead top buttons on a capped hood are not a failed keypad. A capped hood that pulls poorly even on its allowed speeds may have a duct or damper issue. ## What you may notice with it. The range hood problems Top speeds disabled after CFM adjustment tends to arrive with. Answer these at the range hood before anyone is booked.

Look behind the grease filters for the under 295 or under 395 CFM label. ### Can a Faber CFM limit be removed later? No. Faber states the setting cannot be changed back once it is completed. ### How do I know if my Faber was limited? Check for the CFM label behind the grease filters, which the installer applies near the rating label. ### Why do two buttons do the same thing on my Faber? After a CFM adjustment, pairs of buttons run at the same level by design. --- **[Read on the site: Faber top speed or intensive button doing nothing: a reduced CFM setting](https://rangehooderepair.center/error-codes/faber-reduced-cfm-setting/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
