Thermador range hood display · also shown as FILTER icon blinks continuously What to do when FILTER blinking (downdraft) 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 Thermador Thermador hoods, inserts and downdraft vents are repaired on a home visit that begins by watching the owner run the fan. ### Source Thermador Masterpiece Series Downdraft Hood Use and Care Guide (UCVM30XS, UCVM36XS) Masterpiece Series downdraft hoods UCVM30XS, UCVM36XS and the deluxe UCVP36XS. ## Before you book, in this order.

Lower the intake, switch the hood off and let the parts cool. If it comes back, it needs a visit. ### Why does my Thermador downdraft ask for filter cleaning every 30 hours? It pulls smoke and grease from right beside the burners, so its filters load faster than those in a hood overhead. Thermador shortens the interval to match. ### Can I stop the blinking on my Thermador downdraft without cleaning the filters? Holding FILTER will stop it, but the grease stays behind and cuts airflow. Thermador also warns against running the vent with grease-laden filters. ### Does it matter which way the Thermador downdraft filters go back in? Yes. Thermador shows them refitted with the half-moon openings facing out for best performance. --- **[Read on the site: Thermador downdraft FILTER blinking: the Masterpiece pop-up vent wants clean filters](https://rangehooderepair.center/error-codes/thermador-downdraft-filter-blinking/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
