Product review (2 stars): irritating fan noise
We've now had this range hood for about 6 months and yes it's pretty to look at, nice halogen lights and all, and it seems generally functional, but the most annoying thing I must say is that the exhaust fan will turn on by itself when the Advance Heat Sentry Technology detects heat and it cannot be turned off manually AT ALL!  So this noisy fan must continually run in your kitchen until it decides it's safe to shut itself off, my god it's unbearable, my wife says it's like water torture.  It stays on for hours, it grates on you, and we absolutely hate it.  You can't even set it on a lower fan speed, nothing stops the incessant noise from the higher fan speed and you can't shut it off. If you buy this product beware- you have been forewarned.
