Range Hoods
Why does my range hood fan speed up when I'm cooking?
Depending upon your hood, you may have a model that features Advanced Heat Sentry™ or Heat Sentry™. This feature in your range hood detects excessive heat and automatically turns on the fan blower speed to the next highest setting or the highest setting. This prolongs the life of the hood by reducing damaging effects of high temperatures. Once the temperature has been reduced, the hood will turn off or return to the last setting used.
