Summary: I bought this range hood about 2 years ago and for the most part I love it. EXCEPT this one really annoying thing. One of the knobs that turns the fan on/off broke within the first few months I owned it. No problem, I called Broan and they sent me two new ones for free. Only one was broken so I saved the other spare. A few months later another knob broke and then another. Now I have two more broken ones.
