Question
My Hardie controller only flashes and will not work at all.  It keeps the current time and station times, but will not turn on manually. I've removed and replaced the battery, as well as disconnect, and still no change. Would it be a solonoid or the entire system? It's 15 years old. Thanks

Answer
sounds like it may be time for a new controller. One last thing - did you reset the controller? with the battery out hold the rest button in which i THINK is on the back of the panel on your model. If that does not work would you like any help finding where to buy another one?
