Some local codes require make-up air above a certain airflow. XO's Code Compliance Control lets an installer cap a 600 CFM hood at 395 CFM; the control blinks three times to confirm, Power Boost is disabled and a sticker should go on the hood. XO range hood display · also shown as CCC, Code Compliance Control What to do when Control blinks 3 times 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 for the 395 CFM sticker the installer was asked to apply. ### 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 XO XO range hoods are repaired on a home call, and a cold draft through the hood or a sluggish fan are both good reasons to book. ### Source XO XOB wall mount hoods manual (XOB24SC to XOB42SC) XO hoods with Code Compliance Control (CCC 395/600 CFM), including XOB, XOBI, XOT, XOR, XOI and XOCEILING models. ## Before you book, in this order. Each step comes from XO's own guidance for Control blinks 3 times on its range hoods. Follow it to the end: the last card says whether this is a visit. 01 Look for the 395 CFM sticker the installer was asked to apply. 02 If the hood now feels weaker, check the filters and the wall or roof cap before blaming the fan. 03 If the hood was set by mistake, book a visit to talk through the duct and make-up air options, since XO says the setting cannot be undone. ### 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 Three blinks at setup are a confirmation, not a failure report. A hood at 395 CFM pulls less than the same model at 600 CFM, so a weaker draw after this change is expected. ## What you may notice with it.

Look for the 395 CFM sticker the installer was asked to apply. ### Can my XO hood be changed back to 600 CFM? No. XO states that once reconfigured for 395 CFM, the hood cannot be reset. ### Why did my XO hood blink three times after the power came back? The CCC setup is done within five seconds of restoring power; three blinks then mean it was set. If nobody pressed a combination, book a visit. ### Does 395 CFM mean my XO hood is broken? No, it is a deliberate cap for code compliance. --- **[Read on the site: XO control blinks three times: set to 395 CFM for good](https://rangehooderepair.center/error-codes/xo-control-blinks-3-times/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
