Fan and lights come on and go off all day long on their own
We installed our Broan-Allure range hood about ten years ago. On three seperate occasions since, the fan has randomly turned on and none of the control buttons would turn it off. After a while it turns itself off. During those same times, when you turned the lights on, they would blink before finally staying on. On each occasion, I have removed the screens and metal underpieces to gain access to the circut board. Once you can see the circut board, remove and replace the 3 Amp fuse that is mounted on the board. (Radio Shack part # 270-1054)...even if the fuse looks good, replace it. Each time this has work for about three years, then it acts up again..
