    Chamberlain 5200 HBC garage door opener schematic

    Post  lazerspot on Fri Nov 25, 2011 6:02 pm

    Greetings ... The problem I am having with my garage door opener is the door will not open or close with the remote but will open and close with the wall mounted key pad. My background is electronics and I know the remote is working and on the control circuit board I can follow the remote signal from the antenna/demodulator right up to the microprocessor. I'm not real happy with the level of the remote signal going to the microprocessor and would like to trace it through the demodulator and that is why I need the schematic. I emailed Chamberlain and got the propriety go jump in the lake which means my next garage door opener will not be a Chamberlain. The unit was manufactured in '99 and owes me nothing but the other unit I have had a problem in it also which turned out to be a relay driver transistor worth about 5 cents. So I hate to spend the bucks for a new one if this is solvable. I'm retired so I have lots of time and no money so I'm hell bent on fixing this one.
    Of all the things I've lost I miss my mind the most so any help would be greatly appreciated. Thanks in advance and take care ... Vic

    Is your wall button doorbell style 1 button, or does it have a lock button on it? Do you live in close proximity to a military base?

    The wall mount opener is actually three buttons, lock, light and a larger one to open the door. It also has a green led mounted behind the big "opener" button.
    We live in Canada and we don't have any military bases as we'd be afraid to offend anyone, besides we couldn't afford any type of fighter plane except a bi-plane, just kidding but no we don't live near any airports, towers nothing that could generate any kind of interference signal.

    thanks for the input though and take care, Vic

    I would imagine you've had your machine repaired since your original post, but if you havent, P.M. me and i can give you some good diagnostic troubleshooting.
