Turn it back on if you still need it; the 4 hours start again from that press. ### Why did my Sirius hood turn off on its own? If it had been running about 4 hours since the last button press, the automatic shutoff did it. ### Can I disable the Sirius 4-hour shutoff? The manuals do not give a way to switch it off. ### Why did my Sirius downdraft close by itself? The same 4-hour shutoff also retracts the downdraft. --- **[Read on the site: Sirius hood switching itself off after hours of running: the 4-hour limit](https://rangehooderepair.center/error-codes/sirius-4-hour-shutoff/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
