Sorry to hear you have had a problem with your hood. While we did experience issues with some early hoods (particularly timers sticking), we have had excellent reliability since the first batch. You have one of the newer Grasslin timers which are pretty much bullet proof. I suspect it is just a freak simple component failure somewhere inside the hood unless it is the lamps. Please feel free to email Pinky (pinky@redseafish.com) and we'll go in to more detail to confirm the issue. Rest assured we will resolve it for you quickly.
