Switch the hood off at the keypad and let the filters and LED strip cool, so the grease firms up. If it comes back, it needs a visit. ### My Dacor hood's Low button blinks but the fan runs fine. Is it broken? No. That blink is the filter alarm after 50 hours of use. Clean the filters and hold Power for 3 seconds. ### Can I still use Low speed while the button blinks on my Dacor hood? Yes. The blink is only a reminder, and every speed keeps working until you reset it. ### How often does the Dacor filter alarm come on? Every 50 hours of fan use, counted by the hood itself whether or not the filters look dirty. --- **[Read on the site: Dacor wall hood Low button blinking: filter alarm](https://rangehooderepair.center/error-codes/dacor-low-button-blinking/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
