On ICON Touch LCD hoods the reminder comes after 60 hours of fan use. With the hood on, the LCD scrolls a message and FAN- blinks; with the hood off, only FAN- blinks. Zephyr's help center describes the same blinking down arrow on other models as a clean filter reminder. Zephyr range hood display · also shown as down arrow button flashing, scrolling filter text on ICON Touch LCD What to do when FAN- button slowly blinking shows on the range hood ### Kind of code Filter reminders The hood has counted enough hours of fan time to ask for its filters: the mesh or baffle grease filters want a wash, or on a recirculating hood the charcoal filters want replacing. Most hoods count hours rather than measure grease, so the light comes on whether the filters are clean or not, and it stays on until it is reset with the key the manual names. A reminder that returns straight after a reset, or a hood that still pulls weakly with fresh filters, is worth a visit. ### Usually leads to Range hood filter and baffle service Cleaning or replacing what catches grease and odor: mesh and baffle filters, charcoal pads on recirculating hoods, and the grease channel. ### 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 Zephyr Zephyr hoods with unresponsive touch controls, dim lamps or a fan that drifts on without being asked are checked at your home. ### Source Zephyr Siena Pro use, care and installation guide Siena Pro (ZSP-E36DS, ZSP-E42DS, ZSP-E48DS) and other ICON Touch LCD hoods at 60 hours; the Anzio and Savona ICON Touch hoods blink a button at 30 hours instead. ## Before you book, in this order. Each step comes from Zephyr's own guidance for FAN- button slowly blinking on its range hoods. Follow it to the end: the last card says whether this is a visit. 01 Wash the grease filters with the hood off and cool. 02 With the entire hood off, press and hold FAN- to reset the reminder; a short press only shows the reset instructions. 03 If FAN- keeps blinking after a proper reset, book a visit to check the keypad and board. ### Still there?

Wash the grease filters with the hood off and cool. If it comes back, it needs a visit. ### Why is the down arrow flashing on my Zephyr hood? Zephyr uses that blink as its clean filter reminder. Clean the filters and do the reset from your manual. ### I pressed FAN- and the Zephyr still blinks. Why? A short press with the hood off just shows how to reset. Hold FAN- with the whole hood off until the reminder clears. ### How often does a Zephyr Siena Pro remind me about filters? Every 60 hours of fan use. --- **[Read on the site: Zephyr FAN- button blinking slowly: the grease filter reminder](https://rangehooderepair.center/error-codes/zephyr-fan-minus-blinking/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
