The downdraft protects its own electronics. When the sensor reads too much heat, AUTO blinks three times and the fan speeds up; the lower speeds light and cannot be chosen until things cool. When the temperature drops, the hood holds its current speed and goes back to normal use. Thermador range hood display · also shown as Auto icon blinks three times What to do when AUTO blinks 3 times shows on the range hood ### Kind of code Heat and grease sensors A sensor inside the canopy has stopped telling the control a believable story: the heat sensor that starts the fan when the air above the burners gets hot, or on some hoods a sensor that reads grease or steam to set the speed. One that reads hot all the time keeps the blower running with the burners long cold; one that reads nothing leaves the automatic mode doing nothing. The sensor, its wiring and the canopy around it are checked at the visit. ### Usually leads to Range hood heat sensor repair Testing the sensor that starts the fan by itself when the burners get hot, so the hood starts when it should and stops when the heat is gone. ### 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 UCVP36XS. ## Before you book, in this order.

Let the blower run; it is clearing heat that could harm components. If it comes back, it needs a visit. ### Why can't I lower the fan on my Thermador downdraft after AUTO blinked? While the sensor still reads high heat, the lower speeds are locked out. Once the intake cools, the hood lets you choose them again. ### Is AUTO blinking on a Thermador downdraft dangerous? It is a protective reaction, not a breakdown. If there is flame or smoke coming from the vent itself, turn the burners off and treat it as a fire, not a code. ### What makes a Thermador downdraft overheat? Very high heat right next to the intake, such as a wide pan searing on the rear burner, is the usual cause. If it happens with gentle cooking, the sensor or its wiring needs a look. --- **[Read on the site: Thermador downdraft AUTO blinks three times: too much heat at the intake](https://rangehooderepair.center/error-codes/thermador-downdraft-auto-blinks/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
