I took our Genie garage door opener apart [the light wasn't working and I read where that was probably caused by the 555 timer] and thought I'd carefully drawn a schematic before doing so, but I failed to label where the 3 wires from the receiver connect to the terminal block on the main unit, and also where the 3 wires from the main unit connect to the terminal block. Regardless, I have the unit back together and when the remote is pressed the receiver relay clicks, but that's the only thing that happens. I'm fairly certain the problem lies with a component on the internal motor controller board. And NO ONE gives out this kind of information. I can't even find it for sale !! But I'll be derned if I'm going to pay $50 for a new controller board when I'm almost 100% certain the problem is a $.59 diode or the like. Plus, I like a challenge and hate getting beat. Any and all help would be very much appreciated. Possibly I could find someone who has the same model unit and they could diagram theirs for me, possibly someone knows where to obtain the real thing. Thanks !!
