I am looking for a schematic for a Stanley Garage door opener Model D1000.
The control board part # is 921-3316 or 921-3528 these are interchangeable parts.
I am having relay problems and really need this schematic in order to trouble shoot this board.
I have googled for 2 days with no luck.
If some has a copy or a link please e-mail me
Try this site http://owneriq.net/owneriqnetwork.html. I have found almost every manual I needed here. I doubt your going to find a schematic drawing for your circuit board. I would guess the board is considered a replacement part and can be ordered as is. If you need parts for the board and know how to perform this kind of work you can go to an electronics store and get components there.
