Hi, we just redid our kitchen. When the Broan was first installed, all was fine with it. Over the course of the next few days, we noticed (on separate occasions) that the halogen lamps were flickering very faintly. The fan is off when this happens (turning the fan on does not make a difference). The strange thing is, when we open our oven door or turn the oven light on, the flickering stops. The oven and hood are wired on separate circuits. Our electrician took a look and all looks to be fine. Any ideas what could be causing these problems? I was thinking the possibly a diode or some other component could be bad on the control board? The good thing is that the hood is still under warranty, and I am going to call Broan support next week, I just wanted to see if anyone had any input. Thanks!
